GENERAL INSTRUCTIONS
• 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.
