I CAUTION
I 10 Operating the engine with the air cleaner off can cause you or others
to be burned. The air cleaner not only cleans the air, it
stops flame
if the engine backfires.
If it isn’t there, and the engine backfires, y(--
could be burned. Don’t drive with it
off, and be cr-ful working on
the engine with the air cleaner
off.
~
NOTICE I
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.
Ib remove the air cleaner filter on a gas engine, turn the wing nuts
counterclockwise. Remove the cover and change the filter.

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 General Motors dealership Sewice Department.
If you do it yourself, be sure to follow all the instructions here, or you could
get
a false reading on the dipstick.
NOTICE I
I
Too much or too little fluid can damage your transmission. Too much can
mean that some of the fluid could come out and fail
on hot engine parts,
I
starting a fire. Be sure to get an accurate reading if you check-your
transmission fluid.
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.

After work is done on the brake hydraulic system, make sure t\
he levels are
above
MIN and below the top of each window.
What To Add:
When you do need brake fluid, use only DOT-3 brake fluid-such \
as Delco
Supreme 11
@ (GM Part No. 1052535). Use new brake fluid from a sealed
container only.
NOTICE
DOT-5 silicone brake fluid can damage your vehicle. Don’t use it.
Don’t let someone put in the wrong kind of fluid. For example, just a
few drops
of mineral-based oil, such as engine oil, in your brake
-]stem can damaae brake svstem parts
so badlv that 1 fll have to
be replaced.
Brake fluid can damage paint, so be careful nor IO spit1 Drake fluid on
your vehicle.
Hydro-Boost Brake System (Hydraulic Pump)
The power steering pump is also used as the Hydro-boost pump. \
Refer to “Power Steering System” in this section when checking flui\
d level
or adding fluid.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together
if the vehicle is to have really good
braking. Vehicles we design and test have top-quality
GM brake parts in
them, as your vehicle does when
it is new. When you replace parts of your
braking system-for example, when your brake linings wear down and you
have to have new ones put in-be sure you get new genuine
GM
replacement parts. If you don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change, for the\
worse. The
braking performance you’ve come to expect can change in many other ways
if someone puts in the wrong replacement brake parts.
