1994 BUICK PARK AVENUE cooling

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
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, belts, 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.

If the coolant inside the coolant recovery tank is boiling,
don’t do anything else
until it cools down.
P
The coolant level should be at or above “FULL COLD.”
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
I NOTICE:
I
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, check to see if the electric
engine fans are running.
If the engine is overheating,
both
fans should be running. If they aren’t, your vehicle
needs service.

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.
