-37C (-34F).
NOTICE:
If necessary to test the freeze protection of a cooling system, a refractometer should be used.
COOLANT SPECIFICATIONS
GM Part Number 1052753 or coolant meeting GM specification 1825-M mixed 50/50 with clear water.
Antifreeze can be added to raise the boiling point of the coolant, but too much will affect the freezing point. Do not use a solution stronger than 70
percent antifreeze, as the freeze level rises rapidly after this point. Pure antifreeze will freeze at +11 F (-11.5 C)
BRAKE SYSTEM FLUID
Many vehicles are currently equipped with see-through master cylinder fluid reservoirs, allowing a visual inspection of the brake fluid. The fluid level
should be within 3 mm (1/8") of the full indicator on the side of the reservoir. If within specification, do not add additional fluid. If the brake fluid level
is below this range, add sufficient fluid to raise the level equal to the full indicator.
NOTICE:
On vehicles equipped with an Antilock Brake System (ABS), the ABS unit hydraulic accumulator must be completely depressurized to properly check
the brake fluid level. Procedures for depressurizing the ABS hydraulic accumulator are included in Section 5E of the Chassis Service Manual. Failure to
fully depressurize the ABS system per service manual procedure could result in overfilling the brake fluid reservoir.
On vehicles that do not allow a visual inspection, thoroughly clean the reservoir cap or cover to avoid brake fluid contamination. Remove the reservoir
cap or cover (compress the rubber boots on reservoir cover diaphragm).
-
On vehicles equipped with compact master cylinders (A, J, N, W body vehicles), brake fluid should be between the minimum and maximum
indicator levels in the opening on top of the reservoir (see service manual for additional information).
-
On vehicles equipped with diagonal split master cylinder, the brake fluid should be within 6 mm (1/4") from the top of the reservoir.
If the fluid level is within specifications, do not add additional fluid. If the fluid level is below the specified level, add sufficient fluid to bring the fluid
level within specification.
BRAKE FLUID REQUIREMENTS
GM Part Number 1052535, Delco Supreme No. 11, or DOT-3 Fluid.
AUTOMATIC TRANSAXLE FLUID - FRONT WHEEL DRIVE
Transaxle Fluid Level Information
When adding or charging fluid, use only DEXRON II. Refer to Section 0B of the Service Manual for maintenance information and servicing intervals.
^
Fluid level should be checked when it reaches normal operating temperatures of 190-200 F (88-93 C). This temperature is reached after
approximately 15 miles (24 km) of highway driving.
^
Fluid color will be red when new.
IMPORTANT:
When new, automatic transmission fluid is red in color. The red dye is to distinguish it from engine oil or antifreeze. The red dye is not an
indicator of fluid quality and is not permanent. As the vehicle is driven the transmission fluid will begin to look darker in color. The color may
eventually appear light brown.
NOTICE:
Do not overfill. Overfilling will cause foaming, loss of fluid and possible damage to the transaxle.
^
Inaccurate fluid level readings will result if checked immediately after the vehicle has been operated:
-
In high ambient temperatures above 90 F (32 C)
-
At sustained high speeds
-
In heavy city traffic during hot weather
-
As a towing vehicle
-
In commercial service (taxi or police use)
