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.

Use only engine oil with the American Petroleum Institute
Certified For Gasoline Engines “Starburst” symbol. Failure \

GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:

Most trips include extensive idling (such as frequent driving in stop and

when outside temperatures are below freezing.
go traffic).
0 You operate your vehicle in dusty areas or off-road frequently.
0 You frequently tow a trailer or use a carrier on top of your vehicle.
If any one of these is true for your vehicle, then you need to change your oil
and filter every
3,000 miles (5 000 km) or 3 months - whichever comes
first.
If none of them is true, change the oil and filter every 7,500 miles (12 500
km) or 12 months - whichever comes first.

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
To remove the rectangular air cleaner filter for the 4.3L (VIN W) engine,
open both clamps and push the rear
of the air cleaner back toward the rear
of the engine compartment to change the filter.
6-13

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
-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 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.
6- 14

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 parts, starting a fire. Be \
sure
to get an accurate reading if you check your transmission flui\
d.
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.
0 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 transmissionfluid 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 ( lO"C), drive the vehicle in THIRD GEAR (D) until
the engine temperature gage moves and then remains steady for ten minutes.
Then follow the hot check procedures.
To check transmissionfluid cold: A cold check is rnaae 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. 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. Keep the engine running.
0 With the parking brake applied, place the shift lever in Park (P).
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 Park (P).
Let the engine run at idle for three minutes or more.

1. Flip the handle
up and then pull out the dipstick
and wipe it with a
clean rag
or paper
towel.
2. Push it back in all the way, wait three seconds and then pul\
l it back out
again.
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 in the acceptable range, push the dipstick back in all
the way; then flip the handle down to lock the dipstick in place.
