WARN I N G
DO NOT service cooling system unless engine has been
allowed to cool down. This is a pressurized cooling sys-
tem and escaping steam or hot coolant will cause seri-
ous 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.
Use test strips (Item 17, WP 0027 00)
to test nitrites level in coolant. If test
strip indicates nitrites level is too low,
notify Unit Maintenance to replace
coolant.
