1997 PONTIAC GRAND AM check engine

When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the
fluid level in your clutch
master cylinder reservoir
and for the proper fluid. See
“Owner Checks and
Services” and
“Recommended Fluids and
Lubricants” in the Index.
., , I . ...
How to Check
The proper fluid should be added if the level is at or
below the STEP mark on the reservoir cap. See the
instructions on the reservoir cap.
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL
J engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 krn) whichever occurs first, if you add only
DEX-COOLd 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 the proper coolant for
your Pontiac will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF (1 29 O C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
6-24

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered
by your
warranty. Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
~ ~~
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The coolant surge tank is located on the passenger’s side
of the engine compartment.
6-26

Surge Tank Pressure Cap
NOTICE:
Your pressure cap is an 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.
When you replace your surge tank pressure cap, a GM
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.
Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system
or
you hear an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.

How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then remove the cap again and
look at the fluid level on the dipstick.
The level should be at the
C mark. If necessary, add only
enough fluid to bring the level up
to the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Index. Always use the proper fluid. Failure to use the proper fluid can cause leaks and
damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is
full.

bd SAMPLE4UXVM072675 bd
This is the legal identifier for your Pontiac. It appears on
a plate in the front corner of the instrument panel, on the
driver’s side. You can see it if you
look through the
windshield from outside your vehicle. The
VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You’ll find this label on your spare tire cover. It’s very
helpful
if you ever need to order parts. On this label is:
your VIN,
0 the model designation,
paint information and
0 a list of all production options and
special equipment.
Be sure that this label is not removed from the vehicle.
Electrical System
Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Pontiac
unless you check with your dealer
first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Pontiac, see “Servicing
Your Air Bag-Equipped Pontiac” in the Index.

Headlamp Wiring
The headlamp wiring is protected by a circuit breaker
located in the instrument panel fuse block. An electrical
overload will cause the headlamps to go on and off, or
in
some cases to remain off. If this happens, have your
headlamp system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible links. This greatly reduces the chance of
damage caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure to
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have a
spare fuse, you can “borrow” one that has the same
amperage. Just pick a feature of your vehicle that you
can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine compartment
fuse block.
