Adding Coolant
If you need more coolant, add the proper mix ut the
coolcrnt mcoveq* tmk.
A CAUTION:
Tbrning the radiator pressure cap when the
engine and radiator are hot can allow steam and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little
-- when the engine and radiator are hot.
Add coolant mix at the recovery tank. but be careful
not
to spill it.
A CAUTION:
You can be burned if' you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it
will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
Radiator Pressure Cap
The radiator pressure cap nust be tightly installed with
the arrows
on the cap lined up with the overflow tube on
the radiator filler neck.
NOTICE:
Your radiator cap is a pressure-type cap and
must be tightly installed to prevent coolant
loss
and possible engine damage from overheating. Be
sure the arrows on the cap line up with the
overflow tube on the radiator filler neck.

Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine cooling system. The thermoskt stops the
tlow 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
tluid 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, 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 FULL COLD mark. If
necessary, add only enough fluid to bring
the level up to
the mark.
To prevent brake fluid contamination, never check or
fill
the power steering reservoir with the master cylinder
cover off.
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.

Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.
There
are only two reasons why the brake fluid level in the
reservoir might
go down. The first is that the brake fluid
lining wear. When new linings are put in, thc tluid levcl
2 wes down to an acceptable level during nonnal brake
c qoes back up. The other reason is that 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 tluid.
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.
A CAUTION
If you have too much brake fluid, it can spill on the
engine. The fluid
will burn if the engine is hot
enough. You
or others could be burned, and your
vehicle could
be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See "Periodic Maintenance
Inspections"
in the Index.

Brake Wear
NOTICE:
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged.
Be careful not to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn
and new pads are needed.
The sound may come and go or
be heard all the time
your vehicle is moving (except when
you
are pushing on the brake pedal firmly).
L
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your vehicle serviced.
I NOTICE: I
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
