1958 Buick Engine Maintenance

1958 Buick Engine Specifications

2-1 TRANSMISSION AND ENGINE MOUNTINGS

The Flight Pitch Dynaflow will utilize a new mounting system. This mounting system incorporates a support and two angular mounts which are located toward the front and on the sides of the transmission case. See Figure 2-1.

The new mounting will reduce engine and transmission vibration as well as road noises. Mountings on the Variable Pitch Dynaflow will be identical to those used in 1957 except that the transmission support will bolt directly to the frame, with the frame boxes eliminated. Proper alignment of the power plant in the frame, without undue strain on the mounts, is as important with our 1958 mounting system as in the past.

The engine mountings for 1958 will remain the same as in 1957.

2-2 COOLING SYSTEM

Radiator

To improve engine cooling for 1958, the radiator width has been increased from 21.9 to 25.2 inches. Along with this improvement, a full shroud will replace the ring-type used in 1957. In addition, the new fan drive incorporated on 1957 air conditioned after model jobs will continue to be used on all models equipped with air conditioning.

NOTE: In 1958 there are five different sized radiators used, depending upon the type of transmission and whether or not air conditioning is present. Care should be taken when R & R work is involved to make certain the correct sized radiator is used.

NOTE: Due to the construction of the radiator support, caution should be taken when the front of the car is raised to be certain that only the front cross member is contacted. Damage will occur to the radiator support if it is used to raise the front of the car.

The Variable Pitch Dynaflow transmission cooler will use 3/8″ pipes and the Flight Pitch Dynaflow transmission will utilize 7/16″ cooler pipes.

Water Pump

In 1958 all series will utilize an aluminum water pump cover. The cover weighs 1.2 pounds. This is 3.2 pounds lighter than the 1957 cast iron cover.
