Downloaded from www.Manualslib.com manuals search engine If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” in the Index
If
you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed
and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (,@)
or DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, push the accelerator until
the engine speed is about twice
as fast as normal idle
speed. Bring the engine speed back to normal idle speed
after two or three minutes. Now see
if the warning stops.
But then, if you still have the .warning, turn ofthe
engine
and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get service
help right
away.

Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise
This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air
to cool the engine. In most every day driving
conditions the clutch is not engaged. This improves fuel
economy and reduces fan noise. Under heavy vehicle
loading, trailer towing and/or high outside temperatures,
the fan speed increases when the clutch engages.
So
you may hear an increase in fan noise. This is normal
and should not be mistaken as
the transmission
slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan will slow
down when additional cooling
is not required and the
clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away as the fan clutch disengages.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if
you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if
you should ever have a “blowout,” here are a few
tips about what
to expect and what to do:
If a front tire fails,
the flat tire will create a drag that
pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer
to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d
use in a
skid.
In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to
go. It may be
very bumpy and noisy, but
you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment
to change a flat tire safely.

The jacking equipment you’ll need is stored inside the
plastic jack cover which is behind the front seats, either
on the center of the wall (extended cab) or on the
passenger’s side
of the wall (regular cab). Turn the wing nut
counterclockwise and remove
the
wheel blocks, jack and wheel wrench.
Your spare tire is stored underneath the rear
of your
vehicle. See “Compact Spare Tire’’ later
in this section
for more information about the compact spare.

NOTICE:
Never remove or restow a tire frodto a stowage
position under the vehicle while the vehicle is
supported by a jack. Always tighten the tire
fully against the underside of the vehicle when restowing.
This is the jack cover for the extended cab. The
cover for the regular cab
is similar. To remove it, turn
the plastic wing
nut counterclockwise. Remove the
jack cover.

from the wheel bolts,
mounting surfaces and spare wheel.

A CAUTION:
Rust or dirt on the wheel, or on the parts to
which it
is fastened, can make the wheel nuts
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 cloth 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.

Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.
7. Place the spare on the wheel mounting surface.
8. Put the nuts on by
hand. Make sure the
cone-shaped end is
toward the wheel.
Tighten each nut by
’ hand until the wheel is
held against the hub.
If a nut can’t be turned
by hand, use the wheel wrench and
see your dealer as
soon as possible.

Downloaded from www.Manualslib.com manuals search engine Rocking your vehicle to get it out: Using the Recovery Hooks
First, turn your steering wheel left and right. That will
clear
the area around your front wheels. Then shift back
and forth between REVERSE
(R) and a forward gear
(or with a manual transmission, between FIRST
(1) or
SECOND
(2) and REVERSE(R)), spinning the wheels
as little
as possible. Release the accelerator pedal while
you shift, and press lightly
on the accelerator pedal
when the transmission is in gear. If that doesn’t get you
out after
a few tries, you may need to be towed out. Or,
you can use your recovery hooks if your vehicle has
them.
If you do need to be towed out, see “Towing Your
Vehicle” in
the Index.
Your vehicle may be equipped with recovery hooks. The
recovery hooks are provided at the front
of your vehicle.
You may need
to use them if you’re stuck off-road
and need
to be pulled to some place where you can
continue driving.

Downloaded from www.Manualslib.com manuals search engine The recovery hooks, when used, are under a lot of
force. Always pull the vehicle straight out. Never
pull on the hooks at
a sideways angle. The hooks
could break
off and you or others could be
injured from the chain or cable snapping back.
I
NOTICE:
Never use the recovery hooks to tow the vehicle.
Your vehicle could be damaged and it would not
be covered by warranty.

Downloaded from www.Manualslib.com manuals search engine Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood to relieve pressure on the
hood prop.
Remove the hood prop from the slot in the hood and
return the prop to its retainer.
Then pull the hood down firmly to close. It will latch
when dropped from
10 to 12 inches (25 to 30 cm)
without pressing on the hood.
Engine Oil
It’s a good idea to check your engine oil every time you
get fuel. In order
to get an accurate reading, the oil must
be warm and the vehicle must
be on level ground.
The oil dipstick on the 2.2L
engine is under the fill cap.
’* .d. L
The oil dipstick on the
“VORTEC” 4300 engine
is a yellow ring.
Turn
off the engine and give the oil a few minutes to
drain back into
the oil pan. If you don’t, the oil dipstick
might
not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth,
then push it back in all the way. Remove it again,
keeping
the tip down, and check the level.

Downloaded from www.Manualslib.com manuals search engine As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to be
0°F (- 18°C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 20W-50. 7
NOTICE:
Use only engine oil with the American
Petroleum Institute Certified For Gasoline
Engines “Starburst” symbol. Failure to use
the recommended oil can result in engine
damage not covered by your warranty.
GM Goodwrench’ 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.

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You operate your vehicle in dusty areas or off-road
frequently.
You frequently tow a trailer.
The vehicle is used for delivery service, police, taxi
or other commercial application. I
Driving under these conditions causes engine oil to
break down sooner.
If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles
(5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.

To remove this air cleaner, open both clamps and push
the rear of the air cleaner toward the rear of the engine
compartment.
Insert a new air filter. Then replace the air cleaner
assembly, making certain the
PCV air tube is properly
seated in the left hand valve cover and the clamps are
securely fastened.
Refer
to the Maintenance Schedule to determine when to
replace the air filter.
A CAUTION:
F
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,
you could be burned. Don’t drive with
it off, and
be careful working on the engine with the air
cleaner
off.
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.

Downloaded from www.Manualslib.com manuals search engine 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.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
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’s 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.
0 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).
