Fuels, Lubricants, and Coolant
IMPORTANT: NEVER overfill the system. A
pressurized system needs space for
heat expansion without overflowing at
the top of the radiator. Coolant level
should be at bottom of radiator filler
neck.
Air must be expelled from cooling
system when system is refilled. Loosen
temperature sending unit fitting at rear
of cylinder head or plug in thermostat
housing to allow air to escape when
filling system. Retighten fitting or plug
when all the air has been expelled.
After adding new coolant solution, run engine until it
reaches operating temperature. This mixes the coolant
solution uniformly and circulates it through the entire
system. After running engine, check coolant level and
entire cooling system for leaks.
Contact your authorized servicing dealer or engine
distributor, if there are further questions.
