• The water pump must be serviced after removing the engine.  Other cooling system service can be

done with the engine installed in the frame.

• The engine must be cool before servicing the cooling system.

When the coolant temperature is over 100℃ , never remove the radiator cap to release the

pressure because the boiling coolant may cause danger.

• Avoid spilling coolant on painted surfaces because the coolant will corrode the painted surfaces.

Wash off any spilled coolant with fresh water as soon as possible.

• After servicing the system, check for leaks with a cooling system tester.
