Flushing Cooling System
Before filling, flush out the system
thoroughly with clean water. Before flushing
out the radiator, remove the lower radiator
hose to allow a quicker and more efficient
draining.
When flushing the radiator, keep the water
pressure low so the radiator tubes are not
damaged.

Filling Cooling System
Always use a pre-mixed solution of 50/50
clean water and antifreeze. DO NOT fill
system with water and then add antifreeze.
A mixture with less than 40% antifreeze
does not give adequate corrosion protection.
Concentrations of antifreeze above 60% does
not give added freeze protection. The system
is self-venting.
1 Fill the system with clean coolant
through the fill neck in the middle of
the surge tank. The fill rate is not to
exceed 2 gpm (8 L/min.). The engine
should not be running and the heater
control should be on WARM.
2 Fill up to the top of the surge tank.
3 Check the level after running the engine
at high idle for approximately five
minutes. Add coolant as required.
