What To Do If The Cooling Water Temperature of The Diesel Engine Is Too High

Fault phenomenon: The water temperature is too high during the operation of the diesel engine. When the diesel engine is working at full load for a long time, the water temperature is too high and an alarm occurs.

Failure analysis: Factors causing high water temperature in diesel engines include: 1. Lack of coolant in the water tank; 2. Loose or broken fan belt; 3. Damage to the fan; 4. Damage to the water pump and no coolant circulation; 5. Failure of the thermostat; 6. , The external heat sink of the water tank is clogged; 7. The inside of the water tank is clogged or calcified.

Troubleshooting methods: 1. Add enough coolant and check for leakage points; 2. Tension or replace the belt; 3. Replace the fan; 4. Check the water pump and replace it if necessary; 5. Replace the thermostat; 6. Clean the heat sink dust in the room; 7. Replace the water tank.

Maintenance suggestions: Check the coolant level in the water tank frequently to prevent leakage in the cooling system. At the same time, the quality of the coolant must be ensured to reduce the possibility of scaling in the water tank. It is prohibited to use untreated heavy water such as river and lake water instead of coolant. In special circumstances, soft water such as distilled water can be used instead of coolant.
