Diesel Generator Radiator Boiling And Water Overflow

Aug. 08, 2025

The phenomenon of diesel generator set water tank boiling and water overflow refers to the violent water splashing and steam overflow from the radiator or expansion tank. This phenomenon is generally caused by the damage of the cylinder head gasket near the cylinder water jacket hole, which connects the combustion chamber with the water channel. When the piston moves upward for compression or combustion, the high-pressure gas in the cylinder escapes into the water channel from the damaged part of the cylinder gasket, causing a large amount of water and gas to overflow from the overflow pipe and ventilation valve of the filler cap. In severe cases, water is sucked into the cylinder during the intake stroke, causing the engine to stop working.

Causes of Diesel Generator Radiator Boiling and Water Overflow

 

1.Overheating Boiling: Excessively high water temperature exceeding the warning temperature causes water overflow, which is commonly known as boiling.

 

2.Blockage Boiling: Blockages in the cooling system pipelines lead to poor circulation, resulting in water overflow.

 

3.Air Mixture Boiling: Air entering the system, usually caused by incomplete air discharge after replacing the coolant, leads to water overflow.

 

4.Insufficient Coolant Boiling: Operating the engine with insufficient coolant causes water overflow.

 

5.Oil Contamination Boiling: Mechanical failures or other reasons cause engine oil to mix into the coolant, emulsifying and deteriorating the coolant, reducing heat dissipation performance and resulting in water overflow.
