Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more
on this. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. Each of these is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.
Trailer Lighting Systems Wiring

gently
until it snaps into place.
7. Reconnect the electrical connector for the cigarette lighter.
8. Grasp the bottom of the instrument panel extension and install the top
into the groove first. Then, push the bottom
of the extension into place.
9. Install the two nuts and two screws on the extension.
Air Cleaner
If you have the 4.3L engine (VIN Code W) with the rectangular 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.
Make sure the fresh air hose is
still attached after the filter is changed.
Refer to the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services”
in the Index.

Downloaded from www.Manualslib.com manuals search engine 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 your
GM dealer 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.
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 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).
0 At high speed for quite a while.
0 In heavy traffic - especially in hot weather.
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).

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.
How 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.
Add fluid only after checking the transmission fluid
HOT. (A COLD check
is used only’ as a reference.) If the fluid level is low, add only enough of the
proper fluid to bring the level up to the
HOT area for a hot check. It doesn’t
take much fluid, generally less than a int.
Don ’t overjill. We recommend
you use only fluid labeled DEXRON
8 -111, because fluid with that label is
made especially for your automatic transmission. Damage caused by fluid
other than DEXRON@-I11 is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”
0 When the correct fluid level is obtained, push the dipstick back in all
the way; then flip the handle down to lock the dipstick in place.

that need lubrication.
Transfer Case
When to Check Lubricant
Refer to the Maintenance Schedule to determine how often to check the
lubricant. See “Periodic Maintenance Inspections’’ in the Index.
How to Check Lubricant
If the level is below
the bottom
of the filler
plug hole, you’ll need
to add some lubricant.
Add enough lubricant
to raise the level
to the
bottom
of the filler
plug hole.
What to Use

Engine Coolant
The following explains your cooling system and how to add coolant when it
is low. If you have a problem with engine overheating, see “Engine
Overheating”
in the Index.
The proper coolant
for your vehicle will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 1 28 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean wafer (preferably distilled) and one-half
antifreeze that meets
“GM Specification 6038-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to “GM
Specification 6038-M. Use
GM Coolant Supplement (Sealer) with a
complete coolant flush and refill.
If you use this mixture, you don’t need to
add anything else.

How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap and wipe the
dipstick with a clean rag. Replace the cap and completely tighten it. Then
remove the cap again and look at the fluid level on the dipstick.
The level should be at the FULL
COLD mark. Add enough fluid to bring
the level up to the mark.
A fluid loss in this system could indicate a problem. Have the system
inspected and repaired.
What to Add
Refer to the Maintenance Schedule to determine what kind of fluid to use.
See “Recommended Fluids and Lubricants” in the Index.
NOTICE:
When adding power steering fluid or making a complete fluid
change, always use the proper fluid. Failure to use the proper\

fluid can cause leaks and damage hoses and seals.

Downloaded from www.Manualslib.com manuals search engine Brakes
Brake Master Cylinder
Your brake master cylinder is here. It is filled with DOT-3 brake fluid.
There are only two reasons why the brake fluid level in your master cylinder
might
go down. The first is that the brake fluid goes down to an acceptable
level during normal brake lining wear. When new linings are put in, the
fluid level goes back up. The other reason is that fluid
is leaking out of the
brake system.
If it is, you should have your brake system fixed, since a leak
means that sooner or later your brakes won’t work well, or won’t work at
all.
So, it isn’t a good idea to “top off’ your brake fluid. Adding brake fluid
won’t correct a leak.
If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is done on the brake
hydraulic system.
A CAUTION:
If you have too much brake fluid, it can spill on the engine. The
fluid will burn
if the engine is hot enough. You or others could
be burned, and your vehicle could be damaged. Add brake fluid \
only
when work is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to check your brake
fluid. See “Periodic Maintenance Inspections” in the Index.
