12. COOLING SYSTEM

SERVICE INFORMATION

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.
