Downloaded from www.Manualslib.com manuals search engine Used oil can De 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.

wing nuts to the left. Remove the cover and change the filter\
. Care should be
taken during reassembly to ensure that the cover is on straigh\
t and the
wingnuts properly tightened.
To remove the square air cleaner filter for the 2.2L (VnV.4) and the 4.3L
(VIN W) engines, open both clamps and push the rear of the air cleaner
back toward the rear of the engine compartment to change the filter.

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 and the
PCV air tube is properly seated in the left hand valve cover.
Refer to
the Maintenance Schedule to determine when to replace 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 damage
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 a
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.
