DO NOT service cooling system unless engine has been allowed
to cool down. This is a pressurized cooling system and escaping
steam or hot coolant will cause serious burns.
DO NOT remove cooling system radiator cap when engine is
hot. Allow engine to cool down. Loosen cap to first stop and let
any pressure out of cooling system, then remove cap. Failure to
follow this warning may cause serious burns.
Wear effective eye, glove, and skin protection when handling
coolants. Failure to do so may cause injury to personnel.

be within 1/2 in. (1.3 cm) of bottom

and water to bring level up to cor-
rect level (TB 750-651).
