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 fue\
l economy and
reduces fan noise. Under heavy vehicle loading, trailer towing andlor high
outside temperatures, the fan speed increases when the clutch e\
ngages.
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 whe\
n 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 “blowout” while you’re d\
riving, 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 pu\
lls the vehicle toward
that side. Take your foot off the accelerator pedal and grip the steering wheel
firmly. Steer to maintain lane position, then gently brake to \
a stop well out of
the traffic lane.

Downloaded from www.Manualslib.com manuals search engine If you’re using fuel rated at 91 octane or higher and you still hear heavy
knocking, your engine needs service. But don’t worry
if you hear a little
pinging noise when you’re accelerating or driving up a hill. That’s nor\
mal, and
you don’t have to buy a higher octane fuel to get rid of pinging. It’s the
heavy, constant knock that means you have a problem.
What about gasoline with blending materials that contain oxygen,\
such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no more than
15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
-uel that is more than
5% methanol is bad for your vehicle. Don’t use il
’ an corrode metal parts in your fuel system and also damage plastic
ma rubber parts. That damage wouldn’t be covered under your Wa-
Znd even at
5% or less, there must be “cosolvent! “ and corrosion
Ireventers
in this fuel to help avoid these problem! I
Gasolines for Cleaner Air
Your use of gasoline with detergent additives will help prevent deposits from
forming in your engine and fuel system. That helps keep your engine in tune
and your emission control system working properly. It’s good \
for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are now blended with materials called oxygenates. General
Motors recommends that you use gasolines with these blending ma\
terials,
such as MTBE and ethanol. By doing
so, you can help clean the air,
especially in those parts
of the country that have high carbon monoxide
levels.
In addition, some gasoline suppliers are now producing reformulated \
gasolines. These gasolines are specially designed to reduce vehicle
emissions. General Motors recommends that you use reformulated g\
asoline. By doing
so, you can help clean the air, especially in those parts of the
country that have high ozone levels.
You should ask your service station operators
if their gasolines contain
detergents and oxygenates, and
if they have been reformulated to reduce
vehicle emissions.

Automatic Transmission Fluid
When to Check and Change:
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to de\
termine when
to change your fluid. See “Scheduled Maintenance Services” \
in the Index.
How to Check:
Because this operation can be a little difficult, you may choo\
se to have this
done at a dealership Service Department.
If you
do it yourself, be sure to follow all the instructions here, or \
you could
get a false reading on the dipstick.
I NOTICE
Wait at least 30 minutes before checking the transmission fluid level if you
have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic-especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid must be at normal operating \
temperature,
which is 180°F to 200°F (82°C to 93°C).
To check transmission fluid hot: Get the vehicle warmed up by driving
about
15 miles (24 km) when outside temperatures are above 50°F (10°C). If
it’s colder then 50°F (IO’C), drive the vehicle in D (3rd gear) until the
temperature gage moves and then remains steady for ten minutes.\
Then
follow the hot check procedures.
To check transmission fluid cold: A cold check is made after the vehicle
has been sitting for eight hours or more with the engine off and is used
only
as a reference. Let the engine run at idle for five minutes if outside
temperatures are
50°F (10°C) or more. If it’s colder than 50°F (lO°C), you
may have to idle the engine longer. A hot check must follow when fluid is
added during a cold check.

If you have a 4.3L engine, you will have a flip-top handle. Flip\
the
handle up and then pull out the dipstick and wipe it clean with a rag or
paper towel.
2. Push it back in all the way, wait three seconds and then pull it back out
again. Flip top handle should remain in open position.

PO1 65
3. Check both sides of the dipstick, and read the lower level. The fluid
level must be in the COLD area for a cold check or in the HOT area or
cross-hatched area for a hot check.
4.
If the fluid. level is where it should be, push the dipstick bac\
k in all the
way.
If you have a flip-top handle, flip the handle down to lock it in place.
How To Add Fluid:
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants” in \
the Index.
If the fluid level is low, add only enough of the proper fluid to bring the level
up to the COLD area for a cold check or the HOT area for a hot c\
heck. It
doesn’t take much fluid, generally less than a pint. Don’\
t overfill. We
recommend you use only fluid labeled DEXRON@lIE, because fluids \
with that
label are made especially for your automatic transmission. Damag\
e caused by
fluid other than DEXRON@IIE is not covered by your new vehicle\
warranty.
After adding fluid, recheck the fluid level as described under \
“How To
Check”.
When the correct fluid level is obtained, push the dipstick ba\
ck in all the
way. Flip the handle down
if you have a flip-top handle.

failure. The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle \
Safety
Standard
No. 109. Grades B and A represent higher levels of performance on
the laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is established for\
a tire that is
properly inflated and not overloaded. Excessive speed, underinfla\
tion, or
excessive loading, either separately or in combination, can cause heat buildup
and possible tire failure.
These grades are molded on the sidewalls of passenger car tire\
s.
While the tires available as standard or optional equipment on \
General Motors
vehicles may vary with respect
to these grades, all such tires meet General
Motors performance standards and have been approved for use on \
General
Motors vehicles.
All passenger type (P Metric) tires must conform to Federal
safety requirements in addition
to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully \
ar IT.-
factory to give you the longest tire life and best overall performance.
In most cases, you will not need
to have your wheels aligned again.
However,
if you notice unusual tire wear or your vehicle pulling one way \
or
the other, the alignment may need
to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels may need
to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts, and wheel nuts should be\
replaced. If
the wheel leaks air out, replace it (except some aluminum wheels, which can
sometimes be repaired). See your GM dealer
if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying capacity, di\
ameter,
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 you have the right wheel, wheel bolts, and wheel nuts\
for your
vehicle.
