Points to Remember
NOTE:
When the vehicle is stopped after a few miles of
operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulat-
ing on the radiator and being vaporized when the
thermostat opens, allowing hot water to enter the radia-
tor.
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 bottle.
•
Check coolant freeze point in the system.
•
If frequent coolant additions are required, or if the
level in the recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
•
Maintain coolant concentration of a minimum of 50%
ethylene glycol and high quality water with recom-
mended antifreeze for proper corrosion protection of
your engine cooling system that contains aluminum
components.
•
Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
•
Keep the front of the radiator and air conditioning
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 cooling performance,
poor gas mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.
