Points To Remember
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 coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
•
If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•
Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to MS-12106)
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 thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
