- Low coolant level
- Radiator
- Coolant leak
- Faulty radiator cooling fan (if applicable)
- Faulty pressure relief valve
- Faulty temperature regulator
- Faulty jacket water coolant pump
- Excessive load on the engine
Inspect the coolant level. If necessary, add coolant.
Check the cooling fins on the radiator for dirt and/or for debris. Remove the dirt and/or debris.
- Check the cooling fins on the radiator for damage. Refer to the Systems Operation/Testing and Adjusting manual for instructions for testing and inspecting the cooling system.
- Check the radiator for internal blockage. Check the temperature difference between the inlet and the outlet of the radiator.
Check the cooling system for leaks.
- Inspect the coolant for presence of bubbles.
- Check the cooling system for combustion gases. Inspect the cylinder liners for cracks.
Faulty Engine Cooling Fan (if applicable)
Check for proper operation of the cooling fan.
Check operation of the pressure relief valve and the radiator cap. If necessary, clean the pressure relief valve and/or the radiator cap. Check that the seating surface of the valve is clean and undamaged. If necessary, install new parts.
Check the water temperature regulators for correct operation.
Faulty Jacket Water Coolant Pump
Inspect the impeller vanes at the jacket water pump for damage and/or for erosion. Repair impeller vanes and/or replace the impeller vanes.
Check that the engine is not loaded beyond design.
