GENERAL INFORMATION AND MAINTENANCE 23
AUTOMATIC TRANSMISSION FLUID
Run the engine until it reaches normal oper-
ating temperature. Park the car on a level
surface. With the transmission in Park and
the engine idling, the fluid level on the dip-
stick should be between the "foil" mark and
Vt
inch below "foil" mark. Repkce the dip-
stick making sure that it is pushed folly into
the filler tube.
CAUTION:
Do not overfill the automatic
transmission. Use Dexron® or Type A au-
tomatic transmission fluid or any other
equivalent fluid. One pint raises the level

BRAKE MASTER CYLINDER
Once every 6,000 miles or four months, check
the brake fluid level in the master cylinder.
The master cylinder is mounted on the fire-
wall and is divided into two reservoirs and
the fluid level in each reservoir must be
maintained at V4 inch below the top edge. Use
only heavy-duty brake fluid (DOT 3 or 4),
which is recommended for disc brake appli-
cations. See "Brakes" for details.
neck, or the line on expansion tank-equipped
models.
CAUTION:
Allow the engine to cool con-
siderably and then add water while the en-
gine is running.
STANDARD REAR AXLE
The rear axle oil level should be checked
when the chassis is lubricated. Remove the
plug from the side of the housing. The lubri-
cant level should be maintained at the bot-
tom of the filler plug hole. When repkcing
oil, use SAE 80 or 90 multipurpose hypoid
gear lubricant.
POSITRACTION REAR AXLE
Lubricant level should be checked at each
chassis lubrication and maintained at the bot-
tom of the filler plug hole. Special Positrac-
tion oil must be used in this differential.
CAUTION:
Never use standard differential
lubricant in a Positractton differential.
MANUAL STEERING GEAR
Check the lubricant by removing the center
bolt on the side cover of the steering gear.
Grease must be up to the level of this bolt
hole.
POWER STEERING RESERVOIR
Maintain the proper fluid level as indicated
on the cap of the reservoir. Check this level
with the engine off and warm. Use GM power
steering fluid or its equivalent. Note:
Avoid
using automatic transmission fluid in power
steering units except in an emergency.

COOLANT
Check the coolant level when the engine is
cold. The level of coolant should be main-
tained 2 in. below the bottom of the filler
