1. Low Cooling Efficiency: Excessive inlet water temperature or scale and oil buildup in the cooler reduces heat dissipation.
2. Coolant Circulation Problems: Damaged intermediate baffles in the cooler, cracked or frozen water pipes can cause reduced water flow or leaks. A malfunctioning thermostat, slipping water pump belt, or a damaged fan can also affect circulation.
3. Coolant Contamination: Poor sealing or cracking of the oil cooler or hydraulic transmission oil cooler can allow engine oil to mix with the coolant, forming an oil-water mixture.
4. System Leaks: Cracked radiators, broken water pipes, or faulty switches can all cause coolant leaks.
5. Other Malfunctions: Blocked radiator core tubes, a malfunctioning fan clutch, or poor ventilation in the working environment can also prevent the cooling system from functioning properly.
Regularly checking water quality, removing scale, checking pipe seals, and ensuring the proper functioning of components such as the fan and water pump can effectively prevent these malfunctions.
