1998 PONTIAC GRAND AM hood open

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
A CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong 110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on
the outside temperature, the
kind
of oil you have, and some other things. Instead of
, trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking
your
vehicle. The dealer can give you the best advice for that
particular area.

Low Coolant Warning Light
If this light comes on and
stays on, the vehicle should
be promptly pulled
off the
road and the coolant level checked. See “Engine
Coolant”
in the Index.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
If there are visible signs of steam see “Engine
Overheating’’
in the Index before opening the hood.
Have your vehicle serviced as soon
as you can.
This system is called OBD 11 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate that there is a problem
and service is required.
Malfunctions often will be indicated by the system
before any problem
is apparent. This may prevent more
serious damage to
your vehicle. This system is also
designed to assist your service technician
in correctly
diagnosing
any malfunction.

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.

Engine Overheating
You will find a coolant temperature gage and a low
cooIant warning light
on your vehicle’s instrument
panel. See “Engine Coolant Temperature Gage”
and
“Low Coolant Warning Light” in the Index.
If Steam Is Coming From Your Engine
A CAUTION:
Steam from an overheated engine can burn you
badly, even
if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it
cools down. Wait until
there
is no sign of steam or coolant before you
open the
hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine
if
it overheats, and get out of the vehicle until the
engine
is cool.
I NOTICE: I
If your engine catches fire because you keep
driving
with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered
by your warranty.
5-14

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:
0 Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
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.
?. 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 (a) or
THIRD (3) for automatic transaxles.
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, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then, if you still have the
warning,
turn o@the 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.

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label),
it is designed to operate on fuels that meet
California specifications.
If such fuels are not available
in states adopting California emissions standards, your
vehicle
will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle
may fail a smog-check test. If this occurs, return
to your authorized Pontiac dealer for diagnosis to
determine the cause of failure.
In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be aEected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Pontiac dealer
for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming
in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have
to add
anything to the fuel.
In addition, gasolines containing
oxygenates, such
as ethers and ethanol, and
reformulated gasolines may be available
in your area to
help clean the
air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
I NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't
use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn't
be covered
under your warranty.

Filling a Portable Fuel Container
Checking Things Under the Hood
I A CAUTION:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You
can
be badly burned and your vehicle damaged if this
occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup
bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline.
‘ A CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned.
Be careful not to drop or spill
things that
will burn onto a hot engine.
