pressure cap. At
any time during
this procedure
if
coolant begins to
flow out of the
filler neck,
reinstall the
pressure cap. Be
sure the arrows on
the pressure cap
line up like this.
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, 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 section shows how to use your jacking equipment
to change a flat tire safely.

Downloaded from www.Manualslib.com manuals search engine 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.
NOTICE:
Fuel that is more than 5% methanol is bad for your vehicle.
Don’t use it. It can corrode metal parts in your fuel syst\
em and
also damage plastic and rubber parts. That damage wouldn’t b\
e
covered under your warranty. And even at
5% or less, there
must be “cosolvents” and corrosion preventers in this fuel\
to
help avoid these problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control 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 oxygenates. General Motors
recommends that you use gasolines
with these blending materials, 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 gasoline.
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
deposit control additives and oxygenates, and
if they have been
reformulated to reduce vehicle emissions.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system, starting a fire. Be sure to get
an accurate reading if you check
your transmission fluid.
Wait at least 30 minutes before checking the transmission fluid level if you
have been driving:
0 When outside temperatures are above 90°F (32 ” C).
0 At high speed for quite a while.
0 In heavy traffic - especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should 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 than
50°F (IOOC), drive the vehicle in “D” (3rd Gear) until the
engine 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 (IOOC), you may have to
idle the engine longer. Should the fluid level be low during a cold check,
you must perform a hot check before adding fluid. This will give you a
more accurate reading
of the fluid level.
To check the fluid hot or cold
Park your vehicle on a level place.
With the parking brake applied, place the shift lever in “P” (Park).
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in
“P” (Park).
0 Let the engine run at idle for three minutes or more.

is in the
acceptable range,
push the dipstick
back in all the
way.
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
check. It doesn’t take much fluid, generally less than
a pint. Don’t overfill.
We recommend you use only fluid labeled DEXRON@-I11 or
DEXRON@-IIE, because fluids with that label are made especially for our
automatic transmission. Damage caused by fluid other than DEXRON
-111
or DEXRON@-IIE is not covered by your new vehicle warranty.
d
After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back in all
the way.

Downloaded from www.Manualslib.com manuals search engine Inflation - Tire Pressure
The Certificatioflire label which is on the rear edge of the driver’s door,
shows the correct inflation pressures for your tires, when they’re cold.
“Cold” means your vehicle has been sitting for at least three hours or driven
no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right.
It’s not. If your tires don’t have enough air
(underinflation) you can get:
0 Too much flexing
Too much heat
Tire overloading
0 Bad wear
0 Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation), you can get:
@ Unusual wear
0 Bad handling
6 Rough ride
6 Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire pressure. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflate\
d.
If your tires have valve caps, be sure to put them back
on. They help prevent
leaks by keeping out dirt and moisture.

Downloaded from www.Manualslib.com manuals search engine Temperature - A, By C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laborat\
ory test
wheel. Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead to
sudden tire 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, underinflation, 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 tires.
While the tires available as standard or optional equipment on General
Motors vehicles may vary with respect to these grades, all suc\
h 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 at \
the
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, 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.
