Check coolant level
The cooling system must be filled with coolant and not leak to operate at maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the engine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Frequent removal may prevent
coolant circulation between the engine and the expansion tank during engine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, use the following
procedure:
1 Remove the expansion tank cap.
2 Move the temperature adjustment control to max. heat. Open the drain cocks at the rear left of the
engine block and at the bottom right corner of the radiator.
3 Disconnect the lower right radiator hose.
Filling:
4 Close the drain cocks and reconnect the hose.
5 Fill the expansion tank to the MAX mark or slightly above.
6 Run the engine until hot. Check the cooling system connections for tightness. Recheck the coolant
level.
