cooling BUICK PARK AVENUE 1994 User Guide

When the coolant in the coolant recovery tank is at or
above 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 mix
directly to the radiator but be sure the cooling system
is
cool before you do it.

How to Add Coolant to the Radiator
1
"I
1. You can remove the radiator pressure cap when the
cooling system, including
the radiator pressure cap
and upper radiator hose,
is no longer hot. Turn the
pressure cap slowly to the left
until it first stops.
(Don't press down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
I 3. Fill the radiator
with the proper
mix, up
to the base
of the filler neck.

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 Buick will:
0 Give freezing protection down to -34°F (-37 “C).
0 Give boiling protection up to 262°F (128 “C).
0 Protect against rust and corrosion.
0 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.
I 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.

In most cases, you will not need to have your wheels
aligned again. However, if you notice unusual tire wear
or your vehicle pulling one way or the other,
the
alignment may need to be reset. If you notice your
vehicle vibrating when driving on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted.
If wheel nuts keep coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If the wheel leaks
air, replace
it (except some aluminum wheels, which can
sometimes be repaired). See your Buick dealer if any
of
these conditions exist.
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 Buick
model.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometerlodometer calibration, headlight
aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.

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. 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” or
“SH,
SG, CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE
5W-30 or SAE low-30), see “Engine Oil” in
the Index.
If your vehicle has an Engine Oil Life Monitor, the
monitor will show you when to change the oil. See
“Engine Oil Life Monitor”
in the Index. 2.
Chassis Lubrication -- Lubricate
the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped
with grease fittings, lubricate the
suspension and steering linkage.
3. 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.
4. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
5. 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
protection, corrosion inhibitor level and engine
operating temperature.

ProCarManuals.com

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.
6.
Transaxle Service -- Change both the fluid and filter
every
15,000 miles (25 000 km) if the vehicle is
mainly driven under one or more
of these conditions:
In heavy city traffic where the outside
temperature regularly reaches
90°F (32°C) or
higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing. (With some
models, you shouldn’t ever tow a trailer. See
“Towing a Trailer”
in the Index.)
0 Uses such as found in taxi, police car or delivery
service.
If you do not use your vehicle under any of these
conditions, change both the fluid and filter every
100,000 miles ( 160 000 km).
7. Spark Plug Replacement* -- Replace spark plugs
with the proper type. See “Specifications Chart”
in
the Index.
8. Spark Plug Wire Inspection*-f -- Inspect for burns,
cracks or other damage. Check the boot
fit at the
distributor and at the spark plugs. Replace wires as
needed.
9. Supercharger Oil Check--Check oil every 30,000
(50 000km) or 36 months. Check oil level only on
cold engine. Add the proper synthetic oil. See
“Recommended Fluids and Lubricants” in the Index.
10. Air Cleaner Filter Replacement* -- Replace every
30,000 miles (50 000 km) or more often under dusty
conditions. Ask your dealer for the proper
replacement intervals for your driving conditions.
1 1. Fuel Tank, Cap and Lines Inspection*? -- Inspect
fuel tank, cap and lines (including fuel rails and
injection assembly) for damage or leaks. Inspect fuel
cap gasket for an even filler neck imprint or any
damage. Replace parts as needed. Periodic
replacement
of the fuel filter is not required.
* An Emission Control Service.
-f The US. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the
emission warranty or limit recall liability prior to the completion of vehicle useful life. General Motors. however. urges that all recommended maintenance services be
performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”.
