t do anything
else until
it cools down.
The coolant level should be at the
ADD mark. If it isn’t, you may have a
leak in the radiator hoses, heater hoses, radiator, water
pump or somewhere
else in the cooling system.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered
by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed is doubled
by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn off the engine.

Your use of gasoline with deposit control additives will help preven\
t
deposits from forming in your engine and fuel system. That hel\
ps 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.
Fuels in Foreign Countries
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode,
and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us where
you’re going and give your Vehicle Identification Number (VI\
N).

Engine Oil
It’s a good idea to check your engine oil every time you get fuel. In order to
get
an accurate reading, the oil must be warm and the vehicle must be on
level ground.
Turn
off the engine
and give the oil a few
minutes to drain back
into the oil pan.
If you
don’t, the oil dipstick
might not show the
actual level.

Pull out the dipstick and clean it with a paper towel or cloth, then push it
back in all the way. Remove it again, keeping the tip down.
When to Add Oil
If the oil is at or below the ADD line, then you’ll need to add some oil. But
you must use the right kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications” in the Index.\

NOTICE:
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the cross-hatched area that shows the pro\
per
operating range, your engine could be damaged.
The engine oil filler cap is located on the driver’s side engine valve cover.
Just fill it enough to put the level somewhere in the proper operating range.
Push the dipstick all the way back in when you’re through. \

Downloaded from www.Manualslib.com manuals search engine What Kind of Oil fo Use
Oils of the proper quality for your vehicle can be identified by looking for
the “Starburst” symbol. The “Starburst” symbol indicates that the oil has
been certified by the American Petroleum Institute (API), and
is preferred
for use in your gasoline engine.
If you change your own oil, be sure you use oil that has the “Starburst”
symbol on the front
of the oil container. If you have your oil changed for
you, be sure the oil put into your engine is American Petroleum Institute
certified for gasoline engines.

If your vehicle has four-wheel drive, you will have a remote oil filter. There
is a special access door in the steering linkage shield assembly located under
the radiator support. Twist the screw to lock or unlock the door.
Engine Coolant Heater
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0°F (-18 “C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in
the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
Used oil can be a real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t
ever dispose of oil by putting it in the trash, pouring
it on the ground, into
sewers, or into streams or bodies of water. Instead, recycle it by taking
it to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station or a local recycling center
for help.
Air Cleaner

Downloaded from www.Manualslib.com manuals search engine While reassembling the air cleaner assembly, ensure that the air cleaner
cover tabs are fully inserted into the slots in the air cleaner housing. On the
4.3L (VIN W) engine, also make certain that the PCV air tube is properly
seated in the left hand valve cover.
Refer to the Maintenance Schedule to determine
when to redace the air
filter.
See “Scheduled Maintenance Services” in the Index.
NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt can easily get into your engine, which will d\
amage
it. Always have the air cleaner in place when you’re driving.
Automatic Transmission Fluid

A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
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 choose to have this
done at your GM 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.

Downloaded from www.Manualslib.com manuals search engine 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.
Add fluid only after checking the transmission fluid
HOT. (A COLD check
is used only
as a reference.) If the fluid level is low, add only enough of the
proper fluid to bring the level up to the
HOT area for a hot check. It doesn’t
take much fluid, generally less than a int.
Don ’t overfill. We recommend
you use only fluid labeled DEXRON -111, because fluid with that label is
made especially for your automatic transmission. Damage caused by fluid
other than DEXRON@-I11 is not covered by your new vehicle warranty. 8
After adding fluid, recheck the fluid level as described under “How to
Check.”
0 When the correct fluid level is obtained, push the dipstick back in all
the way; then flip the handle down to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid in your manual transmission doesn’t require changin\

How to Check
Because this operation can be a little difficult, you may choose to have this
done at your GM dealership Service Department.
If you do it yourself, be sure
to follow all the instructions here, or you could
get a false reading.
I 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 parts, starting
a fire. Be sure
to get an accurate reading if you check your transmission fluid.
Check the fluid level only when your engine is off, the vehicle is parked on
a level place and the transmission is cool enough for you to rest your fingers
on the transmission case.
