1955 Buick Owners Guide

1955 Buick Owners Guide

The 1955 Buick Owners Guide is compiled by the Buick Engineering and Service Departments to assist 1955 Buick Owners in obtaining the utmost pleasure and satisfaction from their car.
It is urged that 1955 Buick Owners follow instructions and recommendations closely.



1955 Buick Keys and Locks

1955 Buick Keys and Locks

Identical keys operate all the locks on your Buick. Re­ move the “Knock-out” num­ ber and keep it in a safe place, to be used if your keys are lost or mislaid and duplicates are required. To lock the ignition, turn the key to “lock”; to shut off the ignition but still leave it operative with the key removed, turn the key to “off.” The car may then be operated yet the privacy of the glove and trunk compartments retained.

Lock the ignition and the doors of your car when leaving it unattended. Over 75 % of the vehicles stolen have been left either with the key in the ignition lock or unlocked.



When the engine is cold, depress the accelerator pedal just far enough to engage the starter. If the engine is warm, hot, or partially Flooded, and does not start readily, depress the accelerator pedal to the floor and hold it there until the engine Fires regularly. Always, in starting, be sure the shift lever is in “neutral.” On Dynaflow Drive cars, starter will not operate unless control lever is in “N” or “P.”

CAUTION: It is possible to damage certain parts of the radio if the starter is engaged while the radio is on. As an added precaution, do not attempt to start the engine unless the radio is off. The radio switch may be turned on after the engine is running.



No “break-in” is necessary for your Buick providing it is not abused. However, longer life and better performance can be obtained by avoiding speeds above 50 miles per hour for the First 500 miles and not above 70 miles per hour for the next 500 miles. In all cases, allow time for the engine to warm up properly after a cold start and do not accelerate more rapidly than necessary.

Observance of these precautions allows gears and other moving parts to wear in uniformly. Also, at lower speeds, during this period, the brake surfaces wear in smoothly and equally insuring uniform braking on all four wheels.



1955 Buick Light Switch

1955 Buick Light Switch

Headlights, parking lights, ignition key light, instrument lights, and map lights are controlled from a single four-way switch marked “LIGHTS ” located at the left o f the instrument panel. There are two “out ” positions in the switch obtained by pulling the knob. The first step turns on the parking lights and tail lights, and the second step controls the headlights with the tail lights remaining on. Instrument lights and map lights may be turned on in either step by simply turning the knob. In the extreme left position, both instrument and map light s are “off .” By turning the knob to the right one step the map lights are “on.” The next step to the right illuminates the instrument panel . Continued turning to the right diminishes the intensity of the instrument panel lights. All lights may be turned “off” by simply pushing the control knob all the way in. It is not necessary to turn the knob in either direction before pushing in the knob. When pulled out again, instrument or map lights will be illuminated as previously.

The lower and upper beams o f the headlights are controlled for city and country driving by a foot-operated switch located on the car floor adjacent to the position of the left foot. When the upper beam is in use, a small red light is illuminated on the speedometer just to the right of the trip mileage on Series 50-70 cars and in the center of the turn indicator emblem between the two instrument clusters on Series 40-60.



1955 Buick Windshield Wipers

1955 Buick Windshield Wipers

Vacuum-operated wipers are used for cleaning a large vision area on windshield glasses.

Adjustable speed control is had by turning a knob located on lower edge of instrument panel at left of steering column.



SELECTION – Engine crankcase oils have a definite effect on ease of starting, oil economy, combustion chamber deposits and engine wear. In selecting a specific brand of oil it is essential to consider the reputation of the refiner or marketer. See Page 22 for detailed information on selection of engine crankcase oils.

MAINTAINING PROPER OIL LEVEL – The oil gauge rod is marked with one quart and two quart lines to indicate the amount of oil which must be added to maintain proper level. DO NOT OVERFILL. It is desirable that between changes the same brand of oil be used for additions. See Page 22 for detailed information on crankcase oils.



1955 Buick Fuel

1955 Buick Fuel

As in your selection of motor oil, consider the refinery or marketer in choosing the gasoline for your Buick. Most gasolines will perform satisfactorily but in some cases such as high temperatures or carbon accumulations, a premium gasoline will produce less detonation or “spark rap. ” Normal detonation or “spark rap” is not harmful.

Series 40 Buicks equipped with Synchro-Mesh transmission may use REGULAR fuel, while compression ratios in Series 40 cars equipped with Dynaflow Drive and in Series 50, 60, and 70 cars are sufficiently high to fully utilize PRE­ MIUM fuels, and the most satisfactory performance will be obtained through their use.



Washer is operated by pressing and holding, for a few seconds, the small button on the center of the windshield wiper knob on Series 50 and 70 cars, and by pressing the wiper knob on Series 40-60 cars. Release button, start wiper arms by turning control knob to “ON.” Washer will operate for several seconds before shutting off automatically.

Keep the glass jar filled with water. In freezing weather use Buick windshield washer solvent part No. 980807. Do not use water containing alcohol or other anti-freeze as it will damage car finish.



On the lower roll of the instrument panel just to the right of the ignition switch are three knobs and two switches which control the heating, defrosting, and ventilation of the car.

HEATER AND DEFROSTER OPERATION The operation of the heater and defroster controls is relatively simple by just remembering, heat goes up and cold goes down. Control up, maximum heat. Controls down, maximum outside air. The blowers are boosters under either set of conditions.

1955 Buick Right Hand Control

1955 Buick Right Hand Control

Left Hand Control

Up, regulates thermostat, the higher the warmer in-car temperature.

Down, outside air for ventilation. The farther down the greater the amount of air.

Switch (at top) operates underseat heater. Heats floor, particularly rear. Air circulation in summer. Has high and low position.

Center Control

Up, regulates amount of air to windshield for defrosting or cooling. For maximum defrosting winter range control should be in full up position. Switch, above Auxiliary Vent Co trol (R. H. knob) acts as booster for low car speeds, or when parked.

Right Hand Control

Up, allows outside air to enter through auxiliary heater, mounted at right hand kick pad, onto front Floor. May be used for heating and de-fogging in winter. Must be down when defroster (center control) is up. However, may be used proportionately with defroster.

Down -Outside air for ventilation . The farther down the greater the amount of air. May also be used in winter to provide air For defrosting when outside air intake is plugged with ice or snow .

Switch (at top) operates auxiliary heater for motor. Provides air flow when parked or at low car speeds to defroster, lower Floor level or both depending on position of center and right hand controls.



Should 1955 Buick Owners contemplate hauling a house trailer with their Buick, it is advisable that 1955 Buick Owners follow our instructions covering weight limits, springs, tires, and hitch specifications. To obtain this information, write Buick Motor Division, Service Department, Flint, Mich.


Control of the Variable Pitch Dynaflow Drive is obtained by positioning the control lever mounted directly below the steering wheel. Variable Pitch Dynaflow-equipped cars do not have a clutch pedal and lever may be placed in any position when engine is idling by merely moving the lever. Stops have been placed at certain points in the lever travel so that it is necessary to raise the lever to place it in certain positions. After a little experience driving the car, 1955 Buick Owners will find that it is possible to select a range merely by “feel” and visual reference to the dial will not be necessary. However, the dial is illuminated for night driving and is controlled by the instrument panel lighting circuit.

When required, additional engine “braking” can be obtained by placing lever in “L.”

NOTE: The starting motor circuit on cars equipped with the Dynaflow Drive is so wired that the engine will not start unless the control lever is in either “P” or “N” positions.

There are five positions indicated:

1955 Buick Dynaflow in P

1955 Buick Dynaflow in P


This is a Parking Lock and is to be used in conjunction with the foot operated “Step-on” parking brake. THIS PARKING LOCK MUST NEVER BE APPLIED WHEN CAR IS IN MOTION. Control lever must be raised to be placed in or out of this position. Parking the car with the control lever in “D,” “L,” or “R” positions will not partially brake the car as it does when 1955 Buick Owners leave a conventional transmission “in gear”.

1955 Buick Dynaflow in N

1955 Buick Dynaflow in N


This is neutral and is to be used when towing the car and may be used instead of “P” when car is standing still and engine is running. Control lever must be raised when moving it from “D” to “N” position.

1955 Buick Dynaflow in D

1955 Buick Dynaflow in D


This range is used for all normal forward driving. After the engine has been started, place Control Lever in “D” position and depress accelerator pedal. Nothing more need be done.

The new converter with Variable Pitch Stator Blades enables the driver to select the efficient cruising position or the greater performance position by the normal operation of the accelerator pedal. An added resistance to the accelerator pedal operation is provided near the end of its travel. By fully depressing the pedal through this point the higher performance setting is achieved.

1955 Buick Dynaflow in L

1955 Buick Dynaflow in L


This range is to be used when the “going” is particularly tough, such as deep snow, or sand, or on long steep grades. To operate in this range, simply move the control lever to “L” position and drive as before. This range may also be used for “braking ‘ the car speed on long or steep down grades .

Maximum acceleration from a standing start is obtained by starting in “L” and shifting to “D” at 35 M.P.H. (*ECONOMY NOTE: When driving Dynaflow cars, Buick owners have a choice of good performance with economy or superb performance. Good fuel economy may be obtained by making normal starts and not attempting to obtain maximum acceleration at all times. If, however, 1955 Buick Owners desire maximum performance on every start, 1955 Buick Owners must expect less fuel economy.)

The shift from “L” to “D” or vice versa may be made while the car is in forward motion by merely Ripping the lever. These shifts should not be made at speeds over 40 M.P.H.

1955 Buick Dynaflow in R

1955 Buick Dynaflow in R


This position reverses the car motion. To operate with car standing, raise and move control lever to stop at bottom of lever travel. Depress accelerator pedal for backing car.

Pushing or Towing Car to Start Engine – If it becomes necessary to push a Dynaflow Drive car to start the engine, place shift control lever in Neutral (N) until car speed reaches approximately 15 MPH, then shift into Low (L). Continue to increase car speed until engine cranks (approx. 25 MPH). After engine starts, return control lever to Neutral (N) for engine warm up. It is safer to push car than tow it.




1955 Buick Adjustable Front Seat

1955 Buick Adjustable Front Seat

The front sea t on all Buick models is easily adjusted to any posit ion forward or backward to provide maximum driving comfort.

Manually-operated seats may be adjusted by merely pressing the control lever at the driver’s end of the seat and exerting slight body pressure either forward or backward. When in the desired position, the sea t adjuster mechanism will automatically lock to prevent movement.

Forward or backward movement of power­ operated seats is controlled by a button on the driver’s end of the seat which is pressed in the direction of desired travel. The seat is automatically locked when the control button is released.

Easier rear sea t entrance can be made on all two-door models due to the angular tilting split seat backs.



The steering wheel on your Buick is adjustable “up” and “down” within certain limits. If the location of the wheel does not Fit your particular needs, ask your dealer about changing it for you.



1955 Buick Parking Brake

1955 Buick Parking Brake

This is a mechanically operated brake which locks both rear wheel s. This brake is operated with t he foot and is located on the left side under the instrument panel.

This brake is self-locking and will remain applied until the knob marked “Brake” located at lower left Flange of instrument panel, is pulled out to release. This brake should always be released before the car is driven.

A warning light in the instrument panel lights if the ignition is turned on and the brake is not released. (Standard on Roadmaster, Optional on Series 40, 50, and 60.)



Power brakes operate in the same manner as conventional Buick hydraulic brakes, except that about a third of the effort required to apply the brakes is furnished by the power cylinder. In addition to the reduced effort required, the travel of the brake pedal is reduced by about one third.

The source of power to operate power brakes is furnished by the normal vacuum which is present in the intake manifold of the engine. A vacuum reservoir is provided in the pipe line from the power cylinder to the engine manifold. This tank insures instant response o f the power cylinder when the brake pedal is depressed and also stores sufficient vacuum for 2 or 3 power stops after the engine stops.

After the supply of vacuum in the reservoir has been ex­ pended, the brakes will function unassisted by power but will require higher pressure of the foot on the pedal.




1955 Buick Jack

1955 Buick Jack

(1) Set parking brake, remove hub cap, and loosen wheel bolts.

(2) Place jack directly back of rear wheel in line with bumper bolt head with jack arm hooked in notch in bracket on inside of bumper and raise car until tire clears ground.



1955 Buick Tire Change

1955 Buick Tire Change

(1) Set parking brake and remove hub cap.

(2) Loosen all wheel bolts.

(3) Place jack just outside bumper guard under lower rail in hole provided.

INSTRUCTIONS TO OPERATE DOUBLE ACTION “V” SECTION CAR JACK TO RAISE CAR – With trip lever on side of housing in a horizontal position, and a firm grip on the jack handle, press down or lift up slowly the full travel of the handle. As the ratchet or pawl releases from the rack bar, a distinct click can be heard. Continue the up and down movement of jack handle until car is raised to height desired.

TO LOWER CAR – The trip lever should be in the down or vertical position. To lower the car, operate the jack handle the same as for raising the car.

INSTRUCTIONS TO OPERATE SINGLE ACTION RECTANGULAR SECTION JACK With the trip lever in the horizontal position, the jack will raise the car with a downward movement of jack handle. There is no load on the jack handle during the upward movement of handle.



1955 Buick Hood Operation

1955 Buick Hood Operation

The Buick hood is a conventional front-opening, spring counterbalanced hood of the so-called “alligator” type.

The hood latch is controlled from the front of the car by a lift lever located between the radiator grille and the radiator grille header bar. To open the hood, locate the lever by placing the fingers under the header bar, slightly to the right of center. Lift or push upward firmly and the hood latch will release the hood so that the fingers may be placed between the top of the header bar and bottom Range of the hood. To Iift the hood place fingers between the header and hood at the center and locate the safety latch. Pull forward as far as possible and then raise hood by lifting upward. The hinge design makes it advantageous to pull forward as well as upward for easy raising of hood.

To close the hood, lower it to a near-closed position, then push firmly downward until the latch is fully engaged and the hood cannot be raised even slightly. If not properly locked, the hood will remain partly opened held only by the safety latch.



To operate the turn signals, the ignition switch must first be turned on. The switch l ever on the left of the steering column should then be pushed up for a right turn and down for a left turn. This action causes the front lamp and the stop light mounted at the extremity o f the rear fender to Rash on that side of the car in which direction the turn is to be made. If stop lights are applied at the same time a turn is indicated, the opposite stop light will remain solid.

Verification of the proper functioning of both front and rear lamps is indicated by a flashing of one of the illuminated green arrows, located at the ends of the speedometer on Series 50 and 70 cars and to the right or left of the light indicator emblem, located between the two instruments on Series 40-60.

If the arrow does not light and Rash, after movement of the turn signal lever, it indicates that the signal system is not functioning properly and should be checked for burned out bulbs in either front or rear signal lamps or the bulb which illuminates the green arrows.

Always indicate a turn at a reasonable distance before making the turn.



1955 Buick Trunk Handle

1955 Buick Trunk Handle

The compartment lid lock is located directly below the rear compartment ornament. Insert and turn the key and raise the compartment lid, using lower edge of ornament as a handle. To lock, firmly close lid.




Switch and Volume Control (Left Knob) – The first portion of rotation in a clockwise direction turns on the radio. Further rotation increases volume.

Tone Control (Chrome Plated Lever Behind the Volume Control Knob) – Control in extreme “treble” position gives brilliant reproduction of the full tone range. This position will reproduce speech very clearly and distinctly. Rotation counterclockwise (toward “bass “) diminishes brilliance and accentuates low notes.

Tuning Control (Right Knob) – When tuning manually, or when setting up a station on one of the buttons, remember ­ If the program sounds shrill or distorted, it is probably caused by improper tuning and can be corrected by adjust­ ing the tuning knob slightly. Since the low notes are more affected by tuning than the high tones, it is a good plan to tune the set to a point where the low notes are heard best and the high notes are clear but not shrill.


1955 Buick Sonomatic Radio

1955 Buick Sonomatic Radio

Setting the push buttons to tune to any desired station is a simple procedure requiring no tools or equipment.

Procedure is as follows:

  1. Turn on radio.
  2. Press button to right and at the same time pull it out as far as possible.
  3. With button out, tune in the desired station manually. (Do this very carefully as the push buttons will automatically repeat the tuning each time they are pushed. If incorrectly tuned when set up they will always be incorrect until setting is changed manually.)
  4. Push button in as far as possible. This automatically completes the button set-up and locks the mechanism in position.



1955 Buick Selectronic Radio

1955 Buick Selectronic Radio

Buick’s Selectronic Radio is an innovation in radio tuning and provides a simple method of station selection regardless of locality. Unlike the Sonomatic Buick Radio which automatically tunes known stations in a particular locality, the Selectronic set automatically and quickly tunes in stations all along the dial which fall within the signal strength set by the operator.

Signal strength selectivity may be set at any one of four positions by turning the sensitivity knob located behind the manual tuning knob to either “MORE” or “LESS.” Extreme movement of the knob toward “MORE” will include all available stations. By turning the knob to the extreme “LESS” position, nearly all stations are eliminated except strong local stations. Antenna should be “up” and fully extended.


After setting the sensitivity control knob at any one of the four positions, turn on the set and move the dial indicator by either pressing the foot switch or the selector bar on the front of the set. Touch either momentarily and the dial indicator will automatically move to the next station on the dial having sufficient signal strength to fall within the range for which the sensitivity control is set. By repeating this operation intermittently, the dial indicator will “search” the en­ tire width of the dial and automatically return to the low frequency end of the dial ready to “search” the entire dial again.

Volume is controlled by the knob at the left end of the dial. By simply turning the knob clockwise, volume may be in­ creased. Varying degrees of tone between treble and bass are obtained by turning the knob behind the volume control knob as indicated.

In some cases, when it is desirable to tune the set manually, simply operate the manual tuning knob at the right of the dial as with any conventional radio.

ANTENNA (Both radios) – The Buick radio antenna is located on the left front fender opposite the windshield. The “manually-operated” antenna must be raised and lowered by hand.

The “electrically operated” antenna (optional equipment on all models) may be raised or lowered from inside the car even while driving. A toggle switch mounted on the lower edge of the instrument panel to the left of the steering column raises the antenna when pulled toward the driver and lowers the antenna when pushed for­ ward. For satisfactory radio operation, the antenna should be fully extended.



1955 Buick Clock

1955 Buick Clock

To reset clock, pull knob “A” at top of clock out and turn in desired direction.

To regulate the clock for more accurate timekeeping, place small screwdriver or similar tool in slot in small knob “B” behind the reset knob and turn toward “F ” if clock is running slow, or toward “S” if clock is running fast. It is advisable to move the regulator only one division or graduation at a time. By following this procedure your clock may be regulated to keep exceptionally close time.

FAILURE OF CLOCK TO RUN-IMPORTANT – The electric clock requires special attention when reconnecting a battery that has been disconnected for any reason, a clock that has been disconnected, or when replacing a blown fuse. IT IS VERY IMPORTANT THAT THE INI­ TIAL WIND BE FULLY MADE.

To be certain of this, proceed as follows:

(1) Make sure that all other instruments and lights are off.

(2) Connect one terminal of the battery first.

Before permanently connecting the other cable, touch the terminal to its post on the battery. Immediately afterward strike the terminal again to see if there is a spark. If there is, allow the clock to run down until it stops ticking and repeat as above until there is no spark. Then immediately make the permanent connection before the clock can again run down. The clock will run down in approximately 2 minutes.

The above procedure should also be followed when reconnecting the clock after connections have been removed, or when replacing a blown fuse. Be sure to disconnect the battery cable before installing new fuse.

Failure of clock to run may be caused by any of the following:

Blown fuse-discharged battery-corroded battery terminals-wire improperly connected to light switch, fuse block or terminal connection to back of clock-or defective clock.

In replacing fuse, use only 2-ampere AGA fuse on all Series.



For maximum tire service-keep tires properly inflated -use an accurate gauge-after inflating, be sure valve caps are in place and screwed down finger­ tight.


Use air pressure as indicated below for checking proper inflation.

1955 Buick Tire Over Inflation

1955 Buick Tire Over Inflation

1955 Buick Tire Under Inflation

1955 Buick Tire Proper Inflation

1955 Buick Tire Proper Inflation

24 Lbs. (starting pressure) AFTER the car has been standing for three hours or driven less than a mile.

26 Lbs. (city pressure) AFTER driving the car three miles or more BELOW 40 miles per hour.

28 Lbs. (highway pressure) AFTER driving the car three miles or more ABOVE 40 miles per hour.

It is normal for air pressure to build up in a tire due to driving conditions.




1955 Buick Tire Wear

1955 Buick Tire Wear


This change of position helps out uneven wear on front tires and distributes the faster wear on the rear tires over all five tires.



Use soap, warm water, and stiff brush to remove road grime and curb dirt from white sidewall tires.

Use medium or fine steel wool for severe cases.

Do not use gasoline, kerosene, or any oil product that will discolor the sidewalls and rot the rubber.

By comparing air pressure in all tires, any variation in pressures will be evident. To prevent flat tires, investigate and correct a continued loss of air in any tire.



The power operating switch for raising or lowering top is located on lower Flange of instrument panel at right of steering column.

1955 Buick Convertible Top Release

1955 Buick Convertible Top Release



  1. Stop car.
  2. Release catch above windshield.

CAUTION: Before operating power top control button make certain that the top directly above the windshield is raised slightly in order to clear wind­ shield dowels. Close catch.

  1. With ignition switch on, pull control knob away from panel and hold until top is completely lowered.
  2. After top is lowered, raise it slightly by hand and pull the top material and padding out from under the roof bow so that it lays in position shown.
1955 Buick Convertible Top Cover

1955 Buick Convertible Top Cover

  • Fold corners of top material as shown in Fig. 3, roll top material up and tuck down into top compartment, fasten hold down strap.
  • 1955 Buick Raise Convertible Top

    1955 Buick Raise Convertible Top

  • Tuck in surplus top material at sides and install top boot.


    1. Stop car.
    2. Remove top boot and unfasten hold down strap.
    3. Push top control knob forward and hold until top is fully raised.
    4. Draw top down over windshield header dowels and fasten catch to lock top.

    To keep mechanism in good condition the top should be operated at least once a month. CAUTION: DO NOT OPERATE EITHER UP OR DOWN WHILE CAR IS IN MOTION.

    If top is to be left folded for any length of time it should be securely strapped down to prevent chafing of top material. Also, boot should be installed to keep top clean and dry.

    Wiring for power-operated top, side windows and front seat is protected by a 30 ampere circuit breaker having automatic reset.

    CARE OF CONVERTIBLE MODEL TOPS – The ONLY METHOD RECOMMENDED for cleaning convertible top material is the use of lukewarm (not hot) water, and a mild (not caustic) soap. The top should be cleaned carefully from end to end using a medium stiff brush or sponge. Do not saturate at any point. Do not fold top when wet. Frequent brushing with an ordinary upholstery brush or stiff whisk broom is helpful in preventing dust and dirt from imbedding itself in the fabric.

    CARE OF PLASTIC BACK WINDOW – To avoid scratches to which the back window is susceptible, use only a soft cotton cloth moistened with tepid (not hot) water and mild (not caustic) soap. Rinse with clear water and dry with a slightly moistened soft, clean cloth. NO OTHER CLEANING METHOD IS RECOMMENDED.



    1955 Buick Power Windows

    1955 Buick Power Windows

    Each panel is equipped with an operating button which is pushed down to lower the window, and pushed up to raise the window.




    Adjust front seat forward and open each rear door before folding rear seat cushion and back. This will prevent scuffing the seat back.



    There are two numbers which identify your car. They are recorded by the License Bureau of the state in which your car is licensed.

    Serial Number-All Series

    The serial number is located on a plate affixed to the left front pillar post below the belt molding line and is visible by opening the left front door.

    1955 Buick Serial Number Location

    1955 Buick Serial Number Location

    Engine Number

    The engine number is located on the outside of the left bank of cylinders on an extension of the top face of the block, halfway back.

    1955 Buick Engine Number Location

    1955 Buick Engine Number Location

    The 264 engines are further identified by a cast groove approximately Ys” wide on the side of the ex tension which was provided for stamping the serial number.



    1955 Buick Battery

    1955 Buick Battery

    CAUTION-Electric storage batteries give off highly inflammable hydrogen gas when charging and continue to do so for some time after receiving a steady charge.

    Under no condition should an electric spark or an open Flame be allowed near the battery, particularly in the vicinity of the vent caps.

    Batteries in all series are 12-volt.

    Before doing any work around a battery a metallic con­ tact between the car bumper and the ground should be made to remove the possibility of a static charge causing a spark in the vicinity of the battery. A long metal bar or a metal chain of sufficient length will accomplish this.



    1955 Buick Radiator

    1955 Buick Radiator

    The Buick cooling system is a sealed pressure type which raises the coolant boiling point. There is no need to check coolant level as long as the operating temperature remains normal. Never check level until the engine has been stopped for several minutes. When checking level, always remove cap slowly to be sure the engine has cooled enough to remove the pressure even at normal temperatures.

    The system should be drained twice a year. It is important that a rust preventive be added when refilling. Proper coolant level is stamped on the radiator tank as shown­ DO NOT FILL ABOVE THIS LINE.

    CAUTION -When installing anti-freeze, do not use solutions that contain salt, oils, kerosene, glucose or honey.

    The cooling system has been treated at the factory with a special patented stop leak and inhibitor.

    If, for any reason, the system is ever completely drained, “Buick Radiator Stop Leak and Cooling System Conditioner,” Part No. 981441, should be added for maximum protection.



    (Synchro-Mesh Transmission)

    There should be 3/4 of an inch to 1 inch “lash ” or free movement in the clutch pedal at all times. Unless some “lash ” is maintained the clutch may slip, necessitating replacement of clutch parts due to excessive heat and wear.



    The parts of the car that have been chrome plated can best be preserved by frequent washing and waxing. The chlorides now being used by most city and state highway departments for melting ice and snow in winter and laying dust in summer are very harmful to chrome plated parts.



    1955 Buick Speedometer Trip Mileage

    1955 Buick Speedometer Trip Mileage

    The Buick speedometer on the 50-70 series only, is equipped with a reset knob so that the trip mileage dial can be set to zero at the start of a trip. To reset to zero, merely push in knob and turn in clockwise direction until all digits read zero. To adjust forward, push in knob and turn in counter­ clockwise direction. This resets reading forward by tenths of a mile.



    1955 Buick Lamp Bulbs

    1955 Buick Lamp Bulbs



    The rear door locks on four-door sedans are designed and are set so that the inside handles “free-wheel” when the locking button is pushed down into lock position. This prevents children from accidentally opening the rear doors. The feature can be changed by any Buick Dealer if it is not desired. When lock is set for free-wheeling it is necessary to raise the lock button before either the inside or outside handles will open the door.



    1955 Buick Fuses

    1955 Buick Fuses

    *THERMAL RELAY-There are no fuses in the headlamp, tail lamp, parking lamp or instrument lamp circuits.

    Protection for these circuits is through a thermostatically controlled current limit relay attached to light switch. When the current load is too heavy, due to a short circuit, the relay opens and closes rapidly thus reducing current sufficiently to protect the wiring from damage. This action continues until the cause is eliminated.



    1955 Buick Specifications and Data

    1955 Buick Specifications and Data



    ENGINE OIL -For instructions on maintaining proper oil level see Page 4.

    The crankcase oil put in at the factory is a high quality Service M.S. oil (see below) with special break-in additives; so should be left in for the first 1,000 miles.

    Ordinarily, no further break-in oils or additives are needed. However, under some adverse driving conditions if such additives are necessary, your Buick dealer has available Buick Engineer-approved products for your use.

    Oil should be normally changed after the first 1,000 miles (see Page 26 for filter service) and every 2,000 to 3,000 miles thereafter. Certain types o f operation however, such as short run, low speed operation in cold weather or in metropolitan areas where driving is limited to ten to twenty miles per day, or in extremely dusty territory, calls for more frequent changing. If there is any question about the change interval best suited for your type of driving, please consult your Buick dealer.

    There are several types of oils manufactured for use in internal combustion engines. For use in the Buick engine we recommend that an oil marked ” for Service M.S.” or ” for Service D.G.” be used for maximum protection under all driving conditions. If Service M.S. or D.G. lore not available, those marked ” for Service M.M.” may be used. Oils marked ” for Service M.L.” are not recommended for use in any Buick engine.

    The following chart will serve as a guide for the selection of the correct SAE viscosity number oil to use under specified atmospheric temperature ranges:

    Chassis – Wipe dirt from lubrication fittings, then apply a good grade of water-resistant chassis lubricant, under pres­ sure, at the following points: (1) Lower Control Arms, inner and outer ends, (2) Upper Control Arms, (3) Steering Knuckles, (4) Tie Rods and Intermediate Rod, Steering link­ age idler arm bushing, (5) Broke and Clutch Pedal Shaft, (6) Clutch Release Equalizer, (7) Brake Pedal (lower end at push rod clevis), (8) Clutch and Brake Linkage may be lubricated with engine oil.

    Synchromesh Transmission and Rear Axle – Check level at filler plug. Maintain level using SAE 90 Multi-Purpose Gear Lubricant (U. S. Army Spec. 2-105B) for temperatures not lower than 10°F below zero. In temperatures continuously below -10°F, use SAE 80. Seasonal or periodic draining and flushing is not required. When complete refilling is required, however, use above lubricant in transmission but use only Factory Hypoid Lubricant in rear axle.

    Dynaflow – Drive-Check Transmission oil level, with trans­ mission oil warm, transmission in Parking and engine idling. If level is more than one inch below “FULL” mark on gauge rod, add oil but do not fill above the “FULL” mark. Distance between “FULL” and “ADD OIL” marks on rod represents one pint. Use oil specified under “Every 25,000 Miles.”

    Steering Gear – Check level at filler plug. Maintain level using Multi-Purpose Gear Lubricant as recommended for rear axle. Do not use pressure when filling. Seasonal or periodic change of lubricant is unnecessary. With power gears, turn wheels to full left turn before filling.

    Power Steering Gear – All models use a pump having an integral reservoir. To check oil level, remove cover from top of reservoir and see if oil comes to specified level. Add oil specified for Dynaflow Drive to maintain level.

    Cranking Motor (Starter) – Apply a few drops of engine oil to the link pins and fulcrum stud of shift yoke.

    Battery – Add distilled water to bring level to ledge a t bottom of slot in well. WARNING: DO NOT FILL ABOVE LEDGE.

    Air Cleaner – Normally serviced every 5000 miles. If car is operating in dusty territory, however, check condition of air cleaner and clean it if dirty. See cleaning and filling instructions under “Every 5000 Miles. ”

    Radiator – Check coolant level only when radiator is cold. Maintain level at line on tank marked, “Filling Level ­ Cold,” using water. Filling above level line or when radiator is hot will cause loss of coolant. CAUTION: Do not remove cap when radiator is hot because coolant will boil and overflow when pressure is released. When refilling cooling system after draining, “Heat Control” lever must be moved to high position. See Page 5.

    NOTE: If cooling system is being drained for storage where freezing is likely to occur, it is necessary to disconnect heater and defroster hoses to thoroughly drain them. If car is Dynaflow equipped, disconnect lower hose at transmission oil cooler.

    Manifold Valve Shaft – Place a few drops of graphited kerosene on shaft at each end and rotate shaft to work lubricant into bearings. If shaft is frozen, free up by tapping ends of shaft lightly with hammer.

    Throttle Control Linkage – Place a few drops of engine oil at connections. Work Lubriplate into Equalizer Shaft bearings and wipe off surplus lubricant.

    Generator – Place a few drops of engine oil in cups at both ends of generator. Avoid excessive oiling which may affect brushes and windings. Do not lubricate while generator is in operation.

    Master Brake Cylinder – Thoroughly clean filler cap nut before removal to avoid getting dirt into reservoir. Add fluid as required to bring level to 1/2″ to 1″ below top of filler opening. Use G.M. or Delco Super No. 11 Hydraulic Brake Fluid. NEVER USE RECLAIMED FLUID OR ANY MINERAL 0IL.

    Tires – Inflate all tires to pressures given on page 14.

    WARNING: It is not possible to inflate tires correctly when they are hot.

    Hood Fastener Mechanism – Lightly coat latch lever and pilot with Lubriplate.

    Door Locks and Strikers – On Series 40-60 apply G.M. Door-Ease Lubricant at the following points: (1) Top of bolt housing; (2) Gear teeth on striker. On Series 50-70 apply G.M. Door-Ease Lubricant on (1) Wedge plate on lock; (2) Wedge contact surface on striker. Use only S. A.E. 10 engine oil on lock bolt roller.

    Door Checks and Hinges – On Series 40-60, 50-70, apply Lubriplate or chassis lubricant to hold-open springs in front door hinges. Use same lubricant sparingly on lugs of all rear door check links. On check link pins of rear doors use Lubriplate. No lubricant required on hinge pins.

    Dome Lamp Door Switches – Apply G.M. Door-Ease Lubricant to end of switch plunger and point of contact on door hinge pillar.

    Glove Box Door – Apply a few drops of light engine oil to glove box door hinges -wipe off surplus oil. Sparingly coat lock striker with G.M. Door-Ease Lubricant.

    Windshield Wiper Cables – Wipe a few drops of light engine oil on cables where they pass over tensioner pulleys. CAUTION: WINDSHIELD WIPER BLADES MUST NOT BE ROTATED BY HAND FOR ANY REASON AS THIS PLACES AN UNDUE STRAIN ON CABLE FASTENINGS.

    Gas Tank Filler Door – Apply a few drops of light engine or penetrating oil on the hinge pins. Wipe off excess to prevent accumulation of fine dust and dirt .

    Rear Compartment Lid Lock – Lightly coat lock latch and lock striker with Lubriplate.

    Lock Cylinders – If key operates roughly in lock cylinder, blow powdered graphite into key slot. DO NOT USE OIL.


    FIRST 2000 MILES

    Lights – Check all lights and aiming of headlamps.


    EVERY 5000 MILES

    Distributor – Remove distributor cap and rotor. Apply a few drops of light engine oil to felt wick in top of cam. Put 1 drop of oil on breaker arm pivot. Work a small amount of M-1172 ball bearing grease into a cloth, then hold cloth on distributor cam while engine is being cranked. CAUTION: AN EXCESSIVE AMOUNT OF GREASE WILL THROW OFF WHEN HOT AND INSULATE THE CONTACT POINTS, CAUSING IGNITION FAILURE.

    Air Cleaner – Every 5000 miles (more often under dusty operating conditions) disassemble air cleaner and wash cleaner element and oil sump with a non-inflammable solvent (kerosene is not recommended). Wipe sump dry and allow cleaner element to drain until dry. DO NOT USE AIR BLAST ON CLEANER ELEMENT. Fill sump to indicated level with one pint SAE 50 engine oil and assemble air cleaner. DO NOT OIL THE CLEANER ELEMENT BECAUSE OIL WILL DRAIN BACK INTO THE SUMP AND CAUSE SUMP TO BE OVERFULL.

    Fuel Filter – Drain to remove accumulated foreign matter. Refilling will be automatic as quickly as engine starts.

    Oil Filter -Change oil Filter element at First 1000 miles, then 5000 miles and each 5000 miles thereafter.* Remove old element, and wipe container out thoroughly with CLEAN cloths. Install new element and new cover gasket. Use only Buick Oil Filter Replacement Element Part No. 5572128 (AC PF-122), or equivalent.

    * In extremely dusty areas, more frequent change may be desirable.

    Pump Operating Countershaft – Carter Carburetor Only ­ Remove the two dust cover attaching screws and apply several drops of engine oil in screw holes above countershaft. Ins tall screws.

    Horn Cable Connector -Pull out plunger and apply a small amount of Lubriplate. Work plunger in and out.

    Lights – Check all lights and aiming of headlamps.


    EVERY 10,000 MILES

    Front Wheel Bearings-Wipe old grease out of hub and wash bearings. Work approximately one tablespoon of wheel bearing lubricant into each ball bearing. The oil seal packings should be examined f or wear or leaking and replaced if necessary.

    NOTE: Do not overfill bearings as excessive lubricant may be forced thru seals and get on brake lining.

    Bearing Adjustment – Take up spindle nut with 10″ wrench until bearings are preloaded at least 1 hex, then rotate wheel 1 revolution to make sure bearings are seated. Back off spindle nut until bearings are loose. Tighten nut until all bearing looseness is just removed, then line up nut to nearest cotter hole and install cotter pin. Do not mistake loose king pin bushing, etc., for wheel bearing looseness. CAUTION: BEARING PRELOAD MUST NOT EXCEED 1/12 TURN OF NUT.

    Rear Shock Absorbers – Inspect and fill to proper level using only Delco Shock Absorber fluid. For filling instructions consult Authorized Buick Dealer. Front shock absorbers are direct acting and cannot be refilled.


    EVERY 25000 MILES

    Dynaflow Transmission – At 25,000 mile intervals the oil pan and torque converter should be completely drained and re-filled with fresh oil. Transmission MUST NOT BE FLUSHED when oil is changed. Use Special Buick Oil for Dynaflow Drive or any Automatic Transmission Fluid, Type A, which has an AO-ATF identification number embossed in lid o f container.

    Put in 3 quarts of specified oil. With engine idling in Parking, complete the refilling to bring oil level to 1%” below “FULL” mark on gauge rod. When transmission oil is warmed up, the oil level should then be at “FULL” mark on gauge rod.



    Rear Wheel Bearings – Rear wheel bearings need not be lubricated more often than 20,000 miles. Whenever rear brakes are relined, or a x le shafts are removed for other work it is advisable to inspect rear wheel bearings and oil seals. Replace seals if leaking or worn. Fill rear wheel bearings and space between oil seals with wheel bearing lubricant. Coat leather edges of seals with lubricant before installation of axle shaft.

    Speedometer Cable – The speedometer cable is factory lubricated with special grease and normally requires no further service unless it becomes noisy. In extremely hot climates, or where considerable dust and water is encountered it may be necessary to lubricate the cable at intervals of approximately 20,000 miles or every two years. It is advisable to have this service performed by an Authorized Buick Dealer to insure use of the special grease in proper quantity.

    Sunshade – If sunshade rod turns hard in support, remove retainer screw, pull. rod from support and apply G.M. Door-Ease Lubricant.

    Do not use oil which may soil trim. Install rod in support and adjust retainer screw t o proper tension.

    Cleaning Leather – (1) Apply a damp (not wet) cloth t o mild soap and rub surface of leather briskly. (2) Wipe with moist cloth without soap. (3) Rub dry with clean, soft cloth.

    “Avoid inhaling exhaust gases when any concentration of these is present in the air, i.e., in a garage, in congested traffic, or when stopped closely behind a vehicle with its motor running. Exhaust gases may have strong odors which normally should give warning of their presence. However, the exhaust gases from some vehicles may not be noticeable under certain conditions and the senses of people react differently. Exhaust gases contain a percentage of carbon monoxide which is a poisonous gas that, by itself, is tasteless, colorless, and odorless.”
