How to Check Limited-Slip Differential
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
“Scheduled Maintenance Services” 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 SAE 75W-90 Synthetic Gear Lubricant (GM Part
No. 12378261) or equivalent meeting GM
Specification
9986 1 15.
To add lubricant when the level is low, use SAE 75W-90
Synthetic Gear Lubricant (GM Part No. 12378261) or
equivalent meeting
GM Specification 99861 15. To
completely refill after draining, add
4 ounces (1 18 ml)
of Limited-Slip Differential Lubricant Additive (GM
Part No. 1052358) or equivalent. Then fill to the bottom
of the filler plug hole with Synthetic Gear Lubricant.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL
8 engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 kmb whichever occurs first, if you add only
DEX-COOL extended life 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.

Radiator Pressure Cap (All Engines)
I NOTICE:
Your radiator cap is an 18 psi (124 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap, a GM cap
is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, a GM thermostat
is
recommended.
Power Steering Fluid
The power steering fluid
reseivoir is locatei toward
the back
of the engine on
the driver’s side.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or you hear
an unusual noise. A fluid loss in this system could indicate
a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace
the cap and
completely tighten it. Then remove the cap again and
look at the fluid level on the dipstick.

NOTICE:
When using concentrated washer fluid,
follow the manufacturer’s instructions
for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean as well as washer fluid.
three-quarters full when it’s
very cold.
This allows for expansion if freezing occurs,
which could damage the tank if
it is
completely full.
Don’t use engine coolant (antifreeze) in
your windshield washer.
It can damage
your washer system and paint.
