Cooling System
Coolant Level Check
WARNING
To prevent personal injury or death from
hot coolant or steam, use only the following
procedure to remove the pressure cap from the
radiator or expansion tank. Allow the engine to
cool first. Wrap a thick, heavy cloth around the
cap. Unscrew the cap slowly to allow pressure
to release from under the cap. After the pressure
has been released, the pressure cap may be
removed.
WARNING
Do not exceed the pressure rating on the
de-aeration tank cap. Ensure that the pressure
rating of the de-aeration tank cap matches that
listed on the side of the tank, or the tank may
burst, causing property damage, personal injury,
or death.
CAUTION
If the coolant should get extremely low and
the engine very hot, let the engine cool for
approximately 15 minutes before adding coolant;
then, with the engine running, add coolant slowly.
Adding cold coolant to a hot engine may crack
the cylinder head or crankcase. Never use water
alone.
Filling Instructions
NOTE: If system has been drained, fill with fresh 50/50 diluted
concentrate coolant or 50/50 pre-mixed coolant. If the system
has been flushed with water, a significant amount of the
freshwater flush will remain in the system. In this case refilling
with a mixture with a higher percentage (75%) of coolant
concentrate is advised in order to achieve a final mixture close
to 50/50.
