1. Improper design or installation location of cooling system: Some cooling systems may have improper design or installation location, resulting in water leakage.
2. Gasket aging or cracking: Loose fastening nuts or aging, deformation, and corrosion of gaskets can lead to seal failure, which is one of the main causes of water leakage in diesel generator sets.
3. Poor installation quality of water tank: Poor installation quality or improper protection of water tank may lead to water leakage.
4. Corrosion of water tank: Quality problems or improper daily maintenance of the water tank can cause corrosion, leading to water leakage.
5. Use corrosive coolant: Operators add corrosive coolant or seawater to the water radiator of the diesel engine, causing damage to the internal water channels and external interfaces of the diesel engine.
6. Aging or damage of cylinder liner sealing ring: The cylinder liner sealing ring gradually loses its elasticity and sealing performance due to high temperature, high pressure, as well as erosion from engine oil and coolant during long-term use.
7. Cracks or sand holes in the body: Cracks or sand holes in the body itself may be caused by defects in the manufacturing process or severe vibrations, impacts, etc. during use.
8. Cylinder head bolts not tightened: The cylinder head bolts are not tightened or the tightening torque is uneven, resulting in poor sealing between the cylinder head and the engine body, and coolant leakage.
9. Malfunction of radiator: The rupture of radiator core tube and poor sealing of water tank cover can also cause water leakage in the body.
10. Damaged water pump seals: Damaged water pump seals can cause coolant to leak from the water pump, which may then flow onto the body.
