1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and
upper radiator hose, is
no longer hot. Turn the pressure
cap slowly counterclockwise until
it first stops. (Don't
press down while
turning the pressure cap.)
If
you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.

Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise
This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air
to cool the engine. In most every day driving
conditions the clutch is not engaged. This improves fuel
economy and reduces fan noise. Under heavy vehicle
loading, trailer towing and/or high outside temperatures,
the fan speed increases when the clutch engages.
So
you may hear an increase in fan noise. This is normal
and should not be mistaken as
the transmission
slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan will slow
down when additional cooling
is not required and the
clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away as the fan clutch disengages.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if
you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if
you should ever have a “blowout,” here are a few
tips about what
to expect and what to do:
If a front tire fails,
the flat tire will create a drag that
pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer
to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d
use in a
skid.
In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to
go. It may be
very bumpy and noisy, but
you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment
to change a flat tire safely.

Downloaded from www.Manualslib.com manuals search engine How to Check Lubricant
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.
6-24

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.
6-25

Downloaded from www.Manualslib.com manuals search engine NOTICE:
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.

Downloaded from www.Manualslib.com manuals search engine Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset and be mounted the same way as the one it replaces.
If you need
to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure
to have the
right wheel, wheel bolts and wheel nuts for your model.
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling
of your
vehicle, make your tires lose air and make
you lose control.
You could have a collision in
which you or others could be injured. Always
use the correct wheel, wheel bolts and wheel
nuts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance and tire or tire chain clearance
to the body and chassis,
See “Changing a Flat Tire” in the Index for more
information.

Putting
a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how many miles it’s been driven, It could fail
suddenly and cause an accident.
If you have to
replace a wheel, use
a new GM original
equipment wheel.
