WARN I N G
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.
Wear effective eye, hand, and skin protection when
handling coolants.
Failure to follow these warnin s may result in injury or
g
death to personnel.
C AU T I O N
Do not add water to pre-mixed antifreeze. If water is
added to pre-mixed antifreeze, it will be diluted and will not
provide proper engine protection. Engine and/or cooling
system damage may occur.
Be sure to identify the type of antifreeze being added, or
engine and/or cooling system damage may occur.
N OT E
Some antifreeze is pre-mixed and requires no water.
Traditional antifreeze requires mixing with an equal
amount of water. Mix antifreeze and water before adding
to machine cooling system to ensure proper 1:1 ratio is
used.
It is allowable to mix traditional and pre-mix antifreeze types in
the same cooling system.
