Air Cleaner
To Remove the Air CIeaner Filter:
If you have the 4.3L engine (VIN Code Z) with the round air cleaner, you
must first remove the engine cover before changing the filter. \
(See “Engine
Cover” earlier in this section.) After removing the engine cover, unscrew the
wing nut to take the cover off the air cleaner. After changing the filter,\
put
the cover back on and be sure the wing nut is properly tight\
ened. Be sure air cleaner lid is correctly positioned to seal out dust and contaminants that
are harmful to your engine.
If you have the
4.3L engine (VIN Code W) with the square air cleaner, you
can change the air cleaner filter without removing the engine cover. Just lift
the hood, unsnap both clips and remove the top. After changing the filter,
snap both clips to secure the air cleaner. Be sure air cleaner lid
is correctly
positioned to seal out dust and contaminants that are harmful to your engine.
Refer to the Maintenance Schedule to determine when to replace the air
cleaner filter. See “Scheduled Maintenance Services” in the Index.

Automatic Transmission Nuid
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 choo\
se 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.
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 part-
starting a fire. Be sure to get an accurate reading
if you check your
transmission fluid.
I
I
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.
While pulling a trailer.
6-20

Downloaded from www.Manualslib.com manuals search engine 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 (lO'C), drive the vehicle in D (Third 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
8 hours or more with the engine off and is used only as
a reference. Let the engine run at idle for
5 minutes if outside temperatures
are
50°F (1 0°C) or more. If it's colder than 50°F (lO"C), you may have to
idle the engine longer.
A hot check must follow when fluid is added during a
cold check.
To check the fluid hot or cold:
Park your vehicle on a level place.
Place the shift lever in P (Park) with the parking brake applied.
With your foot on the brake pedal, move the shift lever throu\
gh each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in
P (Park).
Let the engine run at idle for three minutes or more.
Then, without shutting off the engine, follow these steps:

2. Push it back in all the way, wait 3 seconds and then pull it back out
again.

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 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@IIE, because fluids with that label are ma\

for your automatic transmission. Damage caused by other fluid t\

is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check”.
When the correct fiuid level is obtained, push the dipstick back in all the
