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.
