If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant.
If the differential is at operating temperature (warm),
add enough lubricant
to raise the level to the bottom of
the filler plug hole. If
the differential is cold, add enough lubricant to raise
the level
to 1/2 inch (12 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids
and
Lubricants’’ in the Index.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL R’l (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles ( 166 000 km),
whichever occurs first.
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.

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and the proper coolant for
your vehicle will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
~~ ~~~~ ~ ~~
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. What to
Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half DEX-COOL (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M’ which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and
DEX-COOL (orange-colored,
silicate-free) antifreeze.

r
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair
cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE: I
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
When your engine is cold, the coolant level should be at
ADD, or a little higher. When your engine is warm, the
level should be
LID to FULL HOT, or a little higher.

If you need more coolant, add the proper mix at the
coolant recovery tank.
1 A CAUTION:
Add coolant mix at the recovery tank, but be careful not
to spill
it.
Tbrning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little
-- when the engine and radiator are hot.
A CAUTION:
+-
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

NOTICE: - ~ I
Your radiator cap is a 15 psi (105 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.
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.
