How to Add Coolant to the
Coolant Surge Tank
(CONK)
1. You can remove the coolant surge
tank pressure cap when the cooling
system, including the coolant surge
tank pressure cap and upper radiator
hose, is no longer hot. Turn the
pressure cap slowly about one-quarter
turn to the left and then stop.
If you hear a hiss, wait for that to stop.
A hiss means there is still some
pressure left.
2. Then keep turning the pressure cap
slowly, and remove it.
. Once the pressure cap is off, look
inside the surge tank opening and look
for a small cylinder at the base
of the
opening. This should be covered with
coolant. If the cylinder
is uncovered,
the coolant
in your system is low.
Fill the coolant surge tank with the
proper mix, up to FULL COLD, or
just above the small cylinder at the
base
of the opening.

Service & Appearance Care
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 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,
The proper coolant for your Pontiac will:
Give freezing protection down to
-34°F (-37°C).
Give boiling protection up to 262°F
( 128 “C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.
What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to GM Specification 1825-M
with a complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else. 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.

Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way as
the one
it replaces.
If you need to replace any of your wheels,
wheel bolts, or wheel nuts, replace them
only
with new GM original equipment
parts. This way, you
will be sure to have
the right wheel, wheel bolts, and wheel
nuts for your Pontiac model.
NOTICE:
The wrong wheel can also cause
problems
with bearing life, brake
cooling, speedometer/odometer
calibration, headlight aim, bumper
height, vehicle ground clearance,
and tire or tire chain clearance to the
body and chassis.
Used Replacement Wheels
‘ire Chains
NOTICE:
If your Pontiac has P195/70R14,
P2 15/60VR 14, P195/65R 15 or
P205/55R16 size tires, don’t use tire
chains; they can damage your
vehicle.
If you have other tires, use tire
chains only where legal and on
when you must. Use only
SAE
Class “S” type chains that are the
proper size for your tires. Install
them on the front tires and tighten
them as tightly
as possible with the
ends securely fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you
can hear the chains contacting your
vehicle, stop and retighten them. If
the contact continues, slow down
until- it stops. Driving too fast with
chains on will damage your vehicle.

Maintenance Schedule
Explanation of Scheduled Maintenance
Services
Following are explanations of the services listed in Schedule I
and Schedule 11.
The proper fluids and lubricants to use are listed in Section D.
Make sure whoever services your vehicle uses these. All parts
should be replaced and all necessary repairs done before you or
anyone else drives the vehicle.
NOTE: To determine your engine’s displacement and code, see
“Engine Identification”
in the Index.
1.
2.
Engine Oil and Filter Change* -- Always use SH or SG
Energy Conserving I1 oils of proper viscosity. The “SH” or
“SG” designation may be shown alone or in combination
with others, such as “SH/CD,” “SH, SG, CD,” “SG/CD,”
etc. To determine the preferred viscosity for your vehicle’s
engine (e.g., SAE 5W-30 or SAE 10W-30), see “Engine
Oil”
in the Index.
Chassis Lubrication -- Lubricate suspension and steering
linkage. Lubricate the transaxle shift linkage, underbody
contact points and linkage.
3.
4.
5.
Tire and Wheel Rotation and Inspection -- For proper
wear and maximum tire life, rotate your tires following the
instructions
in this manual. See “Tires, Inspection &
Rotation” in the Index. Check the tires for uneven wear or
damage. If you see irregular or premature wear, check the
wheel alignment, Check for damaged wheels also.
Engine Accessory Drive Belt(s) Inspection -- Inspect the
belt(s) for cracks, fraying, wear and proper tension. Replace
as needed. (Belts can have many small cracks
in individual
ribs without affecting performance.)
Cooling System Service* -- Drain, flush and refill the
system with new or approved recycled coolant conforming
to
GM Specification 1825M. Keep coolant at the proper
mixture as specified. See “Coolant”
in the Index. This
provides proper freeze and boil protection, corrosion
inhibitor level and maintains proper engine operating
temperature.
Inspect hoses and replace if they are cracked, swollen or
deteriorated. Tighten screw-type hose clamps. Clean the
outside of the radiator and air conditioning condenser. Wash
the pressure cap and neck.
To help ensure proper operation, we recommend a pressure
test of both the cooling system and the pressure cap.
