COOLING SYSTEM
SERVICE INFORMATION
GENERAL
Using coolant with silicate 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 services can be done with the engine installed in the frame.
• Avoid spilling coolant on painted surfaces.
• After servicing the system, check for leaks with a cooling system tester.
• Refer to the ECT sensor inspection (page 22-18).
SPECIFICATIONS
TORQUE VALUES
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.
