EID E361Conditions Which Generate This Code:The Electronic Control Module (ECM) detects a problem with the engine's coolant temperature. Information on default settings and ranges for this event code can be found in Troubleshooting, "Event Codes".System Response:The event code will be logged.Possible Performance Effect:361-1NoneTroubleshooting:There may be a problem with the engine's cooling system.Test Step 1. Check the Engine's Cooling System
Verify that the cooling system is filled to the proper level. If the coolant level is too low, air will get into the cooling system. Air in the cooling system will cause a reduction in coolant flow.
Check the radiator or the heat exchanger for an obstruction.
Check for debris or damage between the fins of the radiator core. Debris between the fins of the radiator core restricts air flow through the radiator core.
Check internally for debris, dirt, or deposits on the radiator core. Debris, dirt, or deposits will restrict the flow of coolant through the radiator. Check the filler cap. The inability of the cooling system to sustain a constant pressure in the radiator will cause the boiling point of the coolant to be lower. This will cause cavitation.
Check the mixture of antifreeze and water. Make sure that the recommendations in the Operation and Maintenance Manual are followed.
Check the water temperature regulators. A water temperature regulator that does not open, or a water temperature regulator that partially opens will cause overheating.
Check the water pump. A water pump with a damaged impeller does not pump enough coolant. Remove the water pump and check for damage to the impeller.
If the cooling system for this application is equipped with a fan, check the operation of the fan. A fan that is not turning at the correct speed can cause improper air speed across the radiator core. The lack of proper air flow across the radiator core can cause the coolant not to cool to the proper temperature differential. A loose fan drive belt could limit the operation of the fan.
Check for air in the cooling system. Air can enter the cooling system in different ways. The most common causes of air in the cooling system are the incorrect filling of the cooling system and combustion gas leakage into the cooling system. Combustion gas can get into the system through internal cracks, a damaged cylinder head, or a leaking cylinder head gasket.
Check the cooling system hoses and clamps. Damaged hoses with leaks can normally be seen. Also, hoses can soften during operation. The soft areas of the hose can become kinked or crushed during operation. These areas of the hose may collapse during engine operation. This will restrict the flow of coolant. Hoses become soft and/or get cracks after a period of time. The inside of a hose can also deteriorate, and the loose particles of the hose can become a restriction in the cooling system.
If the cooling system for this application is equipped with an expansion tank, check the shunt line for the expansion tank. The shunt line must be submerged in the
