1998 CHEVROLET EXPRESS warning

Downloaded from www.Manualslib.com manuals search engine Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also
let police know you have a problem. Your front and
rear turn signal lamps will flash on and off. Push the button
at the
top of
the steering column all the
way down
to make your
front and rear turn signals
flash on and off.
Your hazard warning flashers work
no matter what
position your key is in, and even if the key isn’t in.
To turn off the flashers, push the button until the first
click and release.
When the hazard warning flashers are on, your turn
signals won’t work.
Other Warning Devices
If you carry reflective triangles, you can use them to
warn others. Set one up at the side of the road about
300 feet (100 m) behind your vehicle.

Towing Your Vehicle
Try to have your GM dealer or a professional towing
service tow your vehicle. They can provide the right
equipment and know-how to tow
it without damage. See
“Roadside Assistance” in your Index.
If your vehicle has been changed since it was
factory-new, by adding things like fog lamps, aero
skirting, or special tires and wheels, these things could
be damaged during towing.
Before you do anything, turn
on the hazard
warning flashers.
When
you call, tell the towing service:
0 That your vehicle has rear-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can move the shift lever for
the transmission.
0 If there was an accident, what was damaged.

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
-- DRIVE (D).
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 contikties, 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 ofSthe
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 How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
engine coolant at the coolant recovery tank. (See
“Engine Coolant’’
in the Index for more information.)
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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
a 50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

Downloaded from www.Manualslib.com manuals search engine I CAUTION: I
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
When the coolant in the coolant recovery tank
is at the
FULL COLD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing you can try. You can add the proper coolant
mixture directly
to the radiator, but be sure the cooling
system is cool before you do it,
Steam and scalding liquids from a hot cooling
system can blow out and burn
you badly. They
are under pressure, and
if you turn the radiator
CAUTION: (Continued pressure cap
-- even
a lit 0- ey can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool
if you ever have to
turn the pressure cap.

Downloaded from www.Manualslib.com manuals search engine Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
- -
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire.
To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Xhrn off the engine.
To be even more certain the vehicle won't move,
you can put blocks at the front and rear of the
tire farthest
away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end. The following
steps will tell you how
to use the jack and
change
a tire.

Downloaded from www.Manualslib.com manuals search engine If none of them is true, use the long trip/highway
maintenance schedule. 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.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your
skin and could
even cause cancer? 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 used engine oil. (See
the manufacturer's warnings about the use and disposal
of oil products.)
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 properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Air Cleaner (Gasoline Engines)
To remove the air cleaner filter:
1. Loosen the screw bolt to air induct hose.
2. Remove the three bolts holding the air cleaner
housing in place.
3. Remove the full air housing.
4. Unsnap the three clips.
Then tilt the top cover up and back to expose the
filter element.

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant and when to change it. See
“Scheduled Maintenance Services” 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. Refer
to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 kmg whichever occurs first, if you add only
DEX-COOL extended life 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.
A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (1 29” C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
