REPOSITIONING CLOCK RESET KNOB
1954 SERIES 50 & 70 CLOCKS
In cases where the clock reset knob is difficult to grasp and tum, remove the clock and file the holes in the mounting brackets upward 1/16″ so that the clock when reinstalled will be 1/16″ lower. This will give sufficient finger room between the knob and the clock bezel.
An after-jobs change has lengthened the reset knob 1/8″ to compensate for the variations in the location of the instrument trim panel relative to the clock location.

HIGH HEATER TEMPERATURE
1954 ALL SERIES
Some complaints have been received concerning uncomfortably high heater temperatures, when the left control lever is in the low winter range position. The condition may be corrected as follows:
- Remove temperature control valve without disconnecting water hoses as follows:
- Disconnect control wire from temperature control valve.
- Disconnect temperature control valve capillary coil from right kick pad over Auxiliary Heater Outlet Deflector.
(Note: Care should be taken to prevent kinking of heater hoses or damage to temperature control valve capillary coil.)
- Adjust temperature control valve setting as follows:
- Use screw driver to rotate cross recess screw 7/8 tum in counter -clockwise direction as shown in Figure 61.
(Mark original position of screw first.)
- Solder the head of cross recess screw to lock screw in new position. (This adjustment changes low automatic controlled temperature 10 degrees F. lower.)
- 3 Reinstall valve, connect capillary coil and control wire. Make certain that temperature control lever and wire are properly adjusted. When the left control lever on instrument panel is in “off ” position, the cam on the temperature control valve must be in the locked off position. (Extreme clockwise direction.)
A foreign particle may lodge in temperature control valve thereby resulting in improper heat control. To remedy this condition, lock valve wide open (push left lever to extreme up position) and rev up engine a number of times to flush out foreign particles.
HEATER HOSE IMPROPERLY POSITIONED
1954 SERIES 40 & 60
Figure 62 illustrates a condition that occurred on some of the very early production Series 40-60 Buicks. As shown, the heater hose (underseat heater core to ranco valve) was improperly positioned thus causing the hose to lay over the exhaust pipe mounting bracket. (See Fig. 62) This condition, if not corrected, will lead to early failure of the heater hose with subsequent loss of engine coolent. Figure 63 illustrates the corrected position of the heater hose and right ventilator drain hose.
Following is the recommended procedure for correcting the position of the heater hose, drain hose and their retaining clips.
Most of these jobs will already have a hole drilled into the floor pan for the correct position of the heater hose clamp. (See Fig. 63) If this hole is present, remove the No. 1 hose clamp as shown in Figure 62 and move to correct position as shown in Figure 63 .Move drain hose clamp No. 2 as shown in Figure 62 to proper position as illustrated in Figure 63.
If there is not a hole present for the correct position of the No. 1 heater hose clip, See Fig. 62) this hole must be drilled. This drilling procedure is given below. Check for proper position of the No. 3 heater hose clamp under the floor pan. (See Fig 64) This check can be made by lifting the right front seat carpet as illustrated in Figure 64. If there is not a hose clamp in this position, one must be installed. This drilling procedure is given below.
DRILLING OF NO.1 & NO.3 HOSE CLAMP HOLES
- If there is not a hole for the No. 1 heater hose clamp (proper position shown in Figure 63) observe the measuring procedure as given in Figure 64 to locate the hole for the heater hose clamp No. 1. Use 5/32 drill.
- If the lower heater hose clip (No. 3) is not present, drill a 5/32 hole in the position as illustrated in Figure 64
- Seal up unused heater hose clamp hole. (See Figure 64)
- Position the heater hose and drain hose.
- Replace carpet and door cell.
Heater hose should now appear as illustrated in Fig. 63 with adequate clearance between the heater hose and exhaust pipe bracket.
FLAT RATE TIME HEATER HOSE CHANGE.
When necessary to drill both holes .7 hr.
When necessary to drill one hole .6 hr.
When not necessary to drill .5 hr.
1954 REGULATOR INTERFERENCE ON ALL SERIES
An objectionable regulator noise is sometimes present in the radio reception on 1954 models. This regulator interference may be identified as a dull irregular clicking noise present on weak stations, mostly on the low frequency end of the dial. The interference will not appear during idle but at low car speeds – between 20-30 M.P.H.
To check car for regulator interference, tune radio to a weak station at low frequency end of dial. With car standing still, accelerate engine slowly until regulator starts to operate, which will be indicated by a slight flicker of the ammeter pointer. Interference in the radio reception will be heard at this time if it is caused by the regulator.
To correct the above condition connect an additional capacitor, Part No. 1917580, (available only at United Motor Service Station) between ground and battery terminal of the regulator as shown by the arrow in Figure 65.
On all 1954 Buicks built prior to serial numbers as listed below, objectionable ignition noise in the radios is sometimes present. In order to correct this condition it will be necessary to remove the radio from the cars and forward them to your local U.M.S. station for a correction. This is not a campaign, but a correction when necessary. Upon receipt of this Bulletin estimate the approximate number of radio noise complaints received to date and contact your zone office informing them of the number of radios that will require rework from your Dealership. A service package has been made available to your zone office for order by the dealers at no charge to them. Upon receipt of the repair package mail or take the radio (s) to be reworked and the service kit (s) to your local U.M.S. station. The repair package will include the parts necessary to repair the radio as well as a shielded “A” lead (light switch to radio feed wire). The reworked radio when returned from the U .M.S. Service Station will be equipped with this shielded “A” lead cable. When installing the reworked radio the shielded “A” lead must replace the present un shielded “A” lead and be installed with proper ground connections on the auxiliary heater control bracket and radio mounting bolt as shown in Fig.66.
A hood ground clip Part No. 555348, should be placed on the left front fender flange one inch forward of the hood rear rubber bumper on all radio equipped jobs. (See Fig.67)
At this time it would be advisable to check your present inventory and if necessary order through your Buick Parts Department this clip Group No. 9.651 Part No. 555348.
Slight Metallic Rattle in Radio:
On some jobs there is an objectionable metallic rattle caused by the radio buffer condenser striking against the hash compartment cover. This noise can best be identified and located by gently striking the radio grille area of the instrument panel, or if the radio has been removed by striking the left side of front cover when holding the radio. This rattle will be corrected by the U.M.S, Service man, when called to his attention, on all radios forwarded to him for ignition noise corrections.
The first serial numbers of Buick cars with corrected radios are as follows:
South Gate Not Available
Kansas City A-4002330
Arlington. Change in effect at start of 1954 production.
AFA’s may be submitted to Buick for the removal and installation time of the radio. No charge will be made by the U.M.S. Service Stations for this radio rework. Attach the U.M.S. Service Station’s invoice to your A.F.A. for radio R&R and forward to the zone office in the usual manner. More than one car serial number may be listed on an AFA. When this is done the car serial number, model, and repair order number must be listed in the body of the AFA.
Flat rate for R&R which includes installation of new “A” lead are:
Remove & Replace Radio. 4 hr.
Remove & Replace” A” Lead. 1 hr.
Figure 68 illustrates the installation of the 1954 Buick radio receiver and controls. The changes over 1953 procedure that should be noted in Figure 68 are the Allen head screws which now hold the volume and station selector knobs to the radio chassis. The cut-a-way side view of the radio mounted in the dash shows the position of the antenna lead-in cable, trimmer screw, selectronic foot control switch wire, radio “A” lead, and fuse clip. Method of assembling radio chassis under dash is similar to past model Buicks with two 1/4″ bolts clamping the radio between steel braces.
REAR SEAT SPEAKER
The 1953 R ear Seat Radio Speaker Package Group 9.665, Part No. 981335 has been released for use on 1954 Models 41D-46R -48D-52-56R-61-66R-72R-76R.
When using this Package on 1954 Models, there are a few changes in the installation procedure which must be made as follows:
1954 MODELS WITHOUT AIR CONDITIONING Install Speaker Selector S itch and Bracl5et on the Instrument Panel Flange, using the two (2) holes in flange directly below Center Heater Control Escutcheon, with the screws furnished in packaged envelopes. These two (2) holes will have to be drilled out with a 7/32 drill.
The two (2) wire cables from the switch should be inserted thru hole in radio back cover instead of bottom using grommet furnished.
Attach speaker ground wire to reinforcement panel directly below rear compartment front panel, instead of to hinge box as in 1953.
1954 MODELS WITH AIR CONDITIONING OR KLEENEX DISPENSER
Since the 1954 cars with Air Conditioning or a Kleenex Dispenser use the two (2) holes mentioned above, it will be necessary to relocate the switch on these models.
Position switch to the left of the Parking Brake Release Knob on extreme left side of instrument panel flange and drill the switch mounting holes using a 7/32 drill.
Lengthen both wires of the two wire cables by inserting 18 inches of No. 18 wire at switch end of wire, making sure joints are securely soldered and joints of the two wires are taped.
Run wire behind Instrument Panel and insert thru back of radio as listed above. Attach Speaker Ground Wire as mentioned above.
On Air Conditioning Jobs only, it will be necessary to eliminate Gasket No. 7258129 between speaker and rear shelf due to insufficient clearance between air conditioning evaporator and rear shelf.
Figure 69 illustrates the installation of the manually operated antenna for the 1954 Buick models.

AUXILIARY HEATER DEFLECTOR WHISTLE
1954 ALL SERIES
The field has reported that in some of the 1954 jobs, a whistle can be heard when the auxiliary heater is on. This whistle is usually caused by the leading edge of the auxiliary heater deflector lower louvre. The deflector is located at the right kick pad and may be replaced (Deflector, defroster core inner housing air, Gr. 9.779 No. 1163839) First style deflectors may be reworked by cutting down the leading edge of the lower louvre approximately 1/4”:
