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
To add lubricant when the level is low, use Axle
Lubricant (GM Part
No.
12345977)
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 cooling
s
stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5
years or
150,000
miles
(240
000
km)
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, see “Engine Overheating” in
the Index.
A
50/50
mixture of water and DEX-COOL@
