"Boiling" refers to the phenomenon that the temperature of the diesel engine is too high and the coolant is boiling and steaming in the water tank. The main reasons and prevention and elimination methods of diesel engine "boiling" are as follows:1. The inner wall of the radiator heat pipe (core) is too thick, which affects heat dissipation. Pay attention to adding clean cooling water during use; and regularly remove the scale in the water tank;2. The radiator or cooling system leaks water, resulting in insufficient coolant. Check the cause of water leakage, and add enough cooling water after troubleshooting;3. The cylinder head gasket or the cylinder liner is damaged, and the high-pressure gas in the cylinder enters the water cooling system, causing the water tank to "foam" and "boiling" (in this case, it is often accompanied by diesel engine oil emulsification). Check whether the cylinder head gasket or cylinder liner is damaged, and replace it if necessary.
