1994 BUICK PARK AVENUE warning light

Engine Overheating
You will find a warning light about a hot engine on your
Buick instrument panel and if you have the optional
gage cluster, a coolant temperature gage. You will also
find a low coolant warning light.
If Steam Is Coming From Your Engine
NOTICE:
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.
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:
Climb a long hill on a hot day.
Stop after high speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.

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.

Brakes
Brake Master Cylinder
Your brake master cylinder is here. It is filled with
DOT-3 brake fluid. fluid is leaking
out of the brake system. If it is, you
should have your brake system fixed, since a leak means
that sooner or later your brakes won’t work well, or
won’t work at all.
So, it isn’t a good idea to “top off’
your brake fluid. Adding brake fluid won’t correct a
leak. If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake
linings.
You should add (or remove) brake fluid, as
necessary, only when work is done on the brake
hydraulic system.
There are only two reasons why the brake fluid level
in
your master cylinder might go down. The first is that the
brake fluid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the fluid level goes back up. The other reason is that When
your brake fluid falls to a low level, your brake
warning light will come on. A chime will sound if you
try to drive with this warning light on. See “Brake
System Warning Light” in the Index.

INSPECTION
OR SERVICE
Brake System
[nspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake
lines and hoses for proper
hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition.
Also inspect drum brake linings for
wear and cracks. Inspect other brake
parts, including drums, wheel
cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You
may need
to have your brakes inspected
more often if your driving habits or
conditions result
in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced, Also,
if the
brake system warning light stays on or
comes
on, something may be wrong
with the brake system. See ”Brake
System Warning Light”
in the Index. If
your anti-lock brake system warning
light stays on, comes on or flashes,
something may
be wrong with the
anti-lock brake system. See “Anti-Lock
Brake System Warning Light”
in the
Index.
