COOLING SYSTEM
SERVICE INFORMATION
GENERAL
Removing the radiator cap while the engine is hot can allow the coolant to spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator cap.
I
NOTICE
I
Using coolant with silicate corrosion inhibitors may cause premature wear of water pump seals or blockage of radiator
passages. Using tap water may cause engine damage.
• Add coolant at the reserve tank. Do not remove the radiator cap except to refill or drain the system.
• All cooling system service can be done with the engine in the frame.
• Avoid spilling coolant on painted surfaces.
• After servicing the system, check for leaks with a coaling system tester.
• For the ECT sensor switch (coolant temperature indicator) inspection (page 21-12).
• For fan motor switch inspection (page 21-14).
