HIGH COOLANT TEMPERATURE SHUTDOWN
1. Check the coolant level in the overflow jug.
2. Restart the engine and read the coolant temperature to verify a high coolant temperature shutdown.
Stop the engine immediately if the coolant temperature is 210°F (99°C) or more.
3. Allow the engine to cool. Add coolant to the overflow jug if it is low and then check the level of coolant
in the radiator. To access the radiator cap, you must remove the access panel from the top of the enclosure
directly above the radiator. Add coolant until it is 3/4 in. (1.9 cm) below the filler neck. Secure the radiator
cap back into its original position.
4. Check the radiator shroud and ducting for blockage and remove any foreign matter.
5. Inspect coolant hoses, engine block and water pump for visible leaks.
6. Check the tension of the serpentine drive belt for the water pump.
7. If no other problems are found, remove the load on the generator and restart the engine. Check the
coolant temperature and shut the engine down immediately if it starts to overheat. Refer to the engine
operator's manual for additional information on engine overheating.
