Hydraulic Clutch
The hydraulic clutch in your vehicle is
self-adjusting. The clutch master cylinder
reservoir is filled with hydraulic clutch
fluid.
It isn’t a good idea to “top
off’ your
clutch fluid. Adding fluid won’t correct a
leak.
A fluid loss in this system could indicate
a problem. Have the system inspected and
repaired.
When to Check and What to Use:
Refer to the Maintenance Schedule to
determine how often you should check
the fluid level in your clutch master
cylinder reservoir and for the proper fluid.
See “Owner Checks and Services” and
“Recommended Fluids and Lubricants”
in the Index.
How to Check:
The proper fluid should be added if the
level
is below the “STEP’ mark on the
reservoir. See the instructions on the
reservoir cap.
Rear Axle
When to Check and Change Lubricant:
Refer to the Maintenance Schedule to
determine how often to check the
lubricant and when to change
it. See
“Periodic Maintenance Inspections” in
the Index.
How to Check Lubricant:
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant. Add enough lubricant to raise
the level to the bottom of the filler plug
hole.
What to Use
Standard Differential
Use Axle Lubricant (GM Part No.
1052271) or SAE 80W-90 GL-5 gear
lubricant.
Limited-Slip Differential
To add lubricant when the.leve1 is
low, use Axle Lubricant (GM Part
No.
105227 1) or SAE 8OW-90 GL-5 gear
lubricant. To completely refill after
draining, add
4 ounces ( 1 18 ml) of
Limited-Slip Differential Lubricant
Additive (GM
Part No. 1052358). Then
fill to the bottom of the filler plug hole
with Axle Lubricant (GM
Part No.
12345977) or SAE 8OW-90 GL-5 gear
lubricant.
Engine Coolant
The following explains your cooling system and how to add coolant when
it is low. If you have a problem with
engine overheating or if you need to add
coolant to your radiator, see “Engine Overheating” in the Index.
