SERVICE INFORMATION
WORKING PRACTICE
To service the water pump seal, it is necessary to remove the rear engine cover. All the other cooling system services can be
made with the engine in the frame.
Do not remove the radiator c8p when the engine i s hot. The coolant is under pressure and severe scalding could result. The
engine must be cool before servicing the cooling system.
Avoid spilling coolant on painted surfaces. After servicing the system, check for leaks with a radiator tester.
