Cooling System Notes
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows
no evidence of radiator or hose leaks, the vehicle may
be safely driven. The vapor will soon dissipate.
•
Do not overfill the coolant expansion bottle.
•
Check the freezing point of the coolant in the radia-
tor and in the coolant expansion bottle. If deter-
mined that more engine coolant needs to be added
to the radiator, the contents of the coolant expan-
sion bottle must also be protected against freezing.
•
If frequent engine coolant additions are required,
the cooling system should be pressure tested for
leaks.
•
Maintain engine coolant concentration at a mini-
mum 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 over-
flow hoses are not kinked or obstructed.
•
Keep the front of the radiator clean. With air condi-
tioning, 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 thermostat. Other designs
may result in unsatisfactory engine system perfor-
mance, poor gas mileage, and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically.
For the proper maintenance intervals
page 247.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high
brake temperatures, excessive lining wear, and pos-
sible brake damage. You would not have your full
braking capacity in an emergency.
Fluid Level Check — Brake Master
Cylinder
The fluid level of the 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.
For further information
page 297.
WARNING!
•
Use only manufacturer recommended brake fluid.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its per-
formance. 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 pro-
longed 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.
•
Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake fail-
ure. This could result in a collision.
