Trex Accessories TEREX Spare Parts Sharing Article: Troubleshooting and Prevention of Diesel Engine "Boiling" in Loaders. "Boiling" refers to the phenomenon where the temperature of the diesel engine is too high, and the coolant boils and emits steam in the water tank. The main reasons, prevention, and elimination methods for the "boiling" of diesel engines include:

1. The inner wall of the radiator cooling pipe (core) is too thick with scale, which affects heat dissipation. Pay attention to adding clean cooling water during use; And regularly remove scale from the water tank.

2. The radiator or cooling system leaks water, causing insufficient coolant. Check the cause of water leakage in the TEREX spare parts of the Terex accessory, and after troubleshooting, add enough cooling water.

3. The cylinder gasket or cylinder liner is damaged, and high-pressure gas inside the cylinder enters the water cooling system, causing the water tank to "bubble" or "boil" (in this case, it is often accompanied by diesel engine oil emulsification). The cylinder gasket or cylinder liner should be inspected for damage and replaced if necessary.

4. The water pump is damaged, and the cooling water does not circulate or the circulation strength is insufficient. The cause of damage to the water pump should be checked, and a new water pump should be replaced if necessary.

5. The machine can work under high load for a long time, and if the fan belt is too loose and the wind speed is not strong, it may also experience the phenomenon of boiling due to overheating. Reasonably arrange the workload to prevent overheating of the machine.

6. The thermostat is damaged, causing the main circulation to fail and causing the machine to overheat. The Terex spare parts should be replaced with a thermostat.

It should be noted that loaders working in high-altitude cold areas may also experience boiling, mainly due to the freezing inside the radiator and the inability of the coolant to circulate extensively. Therefore, when using loaders in high-altitude areas, attention should be paid to adding insulation devices at the front end of the TEREX spare radiator.
