1998 PONTIAC GRAND AM check engine

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
A CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see it or smell it, so you might not
know it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially
any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep CO out.
You can run the engine to keep warm, but be careful.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
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 transaxle fluid (don’t overfill),
engine oil, 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.
Engine Cooling When mailer Towing
Your cooling system may temporarily overheat during
severe operating conditions.
See “Engine Overheating’’
in the Index.
Towing A Trailer
(Except
3100 V6 Engine)
Your vehicle is neither designed nor intended to tow
a trailer.

i . Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
I NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want.
You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the
possibility
of the vehicles rolling, set the parking
brake firmly
on both vehicles involved in the jump
start procedure.
Put an automatic transaxle in
PARK (P) or a manual transaxle in NEUTRAL (N)
before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter.
Turn off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries.
In addition, it could save your radio!
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
A CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

4. Open the hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
A CAUTION:
5. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a shock.
The vehicles could be damaged, too.
Before you connect the cables, here are some basic
things you should know. Positive
(+) will go to
positive
(+) and negative (-) will go to a metal
engine part.
Using a match near
a battery can cause battery
gas to explode. People have been hurt doing this,
and
some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough
water. You don’t
need to add
water to the AC Delco Freedom@
battery
installed in every new GM vehicle. But
if a battery has ffler caps, be sure the right
amount
of fluid is there. If it is low, add water to
take care of that
first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get it
on you. If you accidentally get it in
your eyes
or on your skin, flush the place with
water and get medical help immediately. Don’t connect positive
(+) to negative (-) or
you’ll
get a short that would damage the battery and maybe
other parts,
too.

Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.

LA CAUTION: I
-1 -
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the
engine, it could lose all coolant. That could
cause an engine
fire, and you could be burned.
Get
any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fan is running. If the
engine is overheating, the fan should be running. If it
isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above FULL COLD, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge
tank pressure cap, is
cool before you do it. (See “Engine Coolant” in the
Index for more information.)
’ /$ CAUTION:
-
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 coolant
surge
tank pressure cap -- even a little -- they
can come out
at high speed. Never turn the cap
when the cooling system, including the coolant
surge
tank pressure cap, is hot. Wait for the
cooling system and coolant surge
tank pressure
cap to cool if you ever have to turn the
pressure cap.
5-18

4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can
feel the upper
radiator hose getting hot. Watch out for the engine
cooling
fan.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more
of the proper mixture to the coolant surge tank
until the level reaches
FULL COLD, or just above
the small cylinder
at the base of the opening.
5. Then replace the pressure cap. Be sure the pressure
cap is tight.
Check the level in the surge
tank when the cooling
system has cooled down.
If the coolant isn’t at the
proper level, repeat Steps
1 to 3 and reinstall the
pressure cap or see your dealer.

A CAUTION: nl
You can be injured and your vehicle could be
damaged
if you try to do service work on a
vehicle without knowing enough about
it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance
task.
0 Be sure to use the proper nuts, bolts and
other fasteners. “English”
and “metric”
fasteners can be easily confused.
If you use
the
wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around
it. This may cause wind noise
and affect windshield washer performance. Check with your dealer before adding equipment to
the outside of
your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM
D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the
AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.
Be sure the posted octane is at least
87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough,
it can damage your engine.
If you’re using fuel rated at
87 octane or higher and you
hear heavy knocking, your engine needs service. But
don’t worry if you hear a
little pinging noise when
you’re accelerating or driving up a
hill. That’s normal,
and you don’t have to buy
a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
