I A Rust or dirt on the wheel, or on the parts to which it is fastened,
4 can make the wheel nub become loose after a time. The wheel
could come off and cause an accident. When you change a wheel,
remove any rust or dirt from the places where the wheel attaches to
the vehicle.
In an emergency, you can use a doth or a paper towel
to
do this; but be sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off.

Remove any rust or dirt from the wheel bolts, mounting surface\
s or spare
wheel. Place the spare on the wheel mounting surface.
I Never use oil or grease on studs or nuts. If you do, the nuts might
L come loose. Your wheel could fall off, causing a serious accident.

Oils with these words on the container will help you save fuel.
This doughnut-shaped logo (symbol) is used
on most oil containers to help
you select the correct oil.
You should look for this on the oil container, and use
only those oils that
display the logo.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives:
Don’t add anything to your oil. Your GM dealer is ready to advise if you think
something should be added.
When to Change Engine c)k
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less than 10 miles
(16 km).
The engine is at low speed most of the time (as in door-to-door delivery,
You tow a trailer often.
or in stop-and-go traffic).
Most trips are through dusty places.
The vehicle is frequently operated off-road.
If any one of these is true for your vehicle, you need to chang\
e your oil and
filter every 3,000 miles (5000 km) or 3 months-whichever comes first.
If none of them are true, change the oil every 7,500 miles (12 500 km) or
12 months-whichever comes first. Change the filter at the first oil change
and at every other oil change after that.
If your vehicle has 4-wheel drive, you ,will have a remote oil filter located
under the hood.
It is mounted to the front left inner fender, behind the
headlights.
Engine Block Heater:
An engine block 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 Block Heater” in the Index.

What to Do with Used Oil:
I A Used engine oil contains things that have caused skin cancer in
- laboratory animals. 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
I used engine oil. I
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 disposing of your used oil, ask
your dealer, a service station
or a local recycling center for help.

To remove the round air cleaner filter for the 2.5L (VIN A), 2.8L (VIN R), and
4.3L (VIN
Z) engines, turn the wing nut counterclockwise. Remove the cover
and change the filter. Care should be taken during reassembly to ensure that
the cover is on straight and the wingnut properly tightened.
To remove the square air cleaner filter for the 4.3L (VIN W) high performance
engine, loosen both wingnuts (one on the duct and one on the\
cover).

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 de\
termine 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 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.
I NOTICE
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.
To get the right reading, the fluid must 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 then 50°F (IO’C), drive the vehicle in D (3rd gear) until the
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 eight hours or more with the engine off and is used
only
as a reference. Let the engine run at idle for five minutes if outside
temperatures are
50°F (10°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.

What to Use:
Use a mixture of clean water (preferably distilled) and antifreeze that meets
“GM Specification 6038-M,” which won’t damage aluminum parts. Also use
GM Engine Coolant Supplement (sealer) with
a complete coolant change. If
you use these, you don’t need to add anything else.
I
Adding only plain water to your cooling system can be dangerous.
proper coolant mix will. Your vehicle’s coolant warning system is set
for the proper coolant mix. With plain water or the wrong mix, your
engine could get
too hot but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others could be burned. Use
- Plain water, or some other liquid like alcohol, can boil before the
II a 50/50 mix of clean water and a proper antifreeze.
NOTICE
J use an improper coolant mix, your engine could overheat and be
badly damaged. The repair cost wouldn’t be covered by your warrant\
y
much water
in the mix can freeze and crack the engine, radiator, hea
core and other
part
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when th\
e engine is cold
and follow the steps under “Adding Coolant” for the prope\
r way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
’‘ you use the proper coolant, you don’t have to add extra inhibitors c-
auditives which claim to improve the system. These can be harmful. ~ ~~~~~

To Check Brake Fluid:
You can check the brake fluid without taking off the cap. Just look at the
windows on the brake fluid reservoir. The fluid levels should be above
MIN. If
they aren’t, have your brake system checked to see if there is a leak.
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.
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.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
