
Do not overfill the coolant expansion bottle.

Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of
the coolant expansion bottle must also be
protected against freezing.

If frequent engine coolant additions are
required, the cooling system should be pres -
sure tested for leaks.

Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper
corrosion protection of your engine which
contains aluminum components.

Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.

Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.

Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine cooling performance, poor gas
mileage, and increased emissions.

In order to ensure brake system performance,
all brake system components should be
inspected periodically
Ú
page 287.
Fluid Level Check — Brake Master Cylinder
The fluid level of the brake master cylinder
should be checked whenever the vehicle is
serviced, or immediately if the brake system
warning light is on. If necessary, add fluid to bring
level within the designated marks on the side of
the reservoir of the brake master cylinder. Be
sure to clean the top of the master cylinder area
before removing cap. With disc brakes, fluid level
can be expected to fall as the brake pads wear.
Brake fluid level should be checked when pads
are replaced. If the brake fluid is abnormally low,
check the system for leaks
Ú
page 355.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
WARNING!

Use only manufacturer's recommended
brake fluid
Ú
page 355. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its perfor -
mance. The proper type of brake fluid for
your vehicle is also identified on the original
factory installed hydraulic master cylinder
reservoir.

To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in a open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.

Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
