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 out any pressure from cooling system, then remove
cap. Failure to follow this warning may cause serious
burns.

handling coolants. Failure to do so may cause injury to
personnel.

Do not add water to pre-mixed antifreeze. If water is added
to pre-mixed antifreeze, it will be diluted and will not pro-
vide proper engine protection and engine and/or cooling
system damage may occur.

engine and/or cooling system damage may occur.
