Start and idle the engine for ap-
prox. 5 minutes. Then, check
coolant in the reservoir tank and
add more coolant as necessary.

ciently cooled down.

damaged.
Clean the radiator thoroughly
before adding antifreeze.

different by manufacturers and
temperature. Refer to the manu-
facturer's manual.
Mix antifreeze with water suffi-
ciently before adding it.

freeze and water with the same
mixture ratio.
