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.
