See your authorized dealer if the coolant level drops

quickly.

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 coolant 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 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 at 50% ethylene glycol

antifreeze (minimum) in water for proper corrosion

protection of your engine that contains aluminum

components.

•

Make sure that the radiator and coolant bottle hoses

are not kinked or obstructed.

•

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 cooling performance, poor gas

mileage, and increased emissions.
