Tips: Reasons for the high temperature of electric diaphragm pump
- Water leakage or insufficient cooling water in the cooling system.
- Inaccurate or malfunctioning water temperature indicator.
- Too much scale in the cooling system and poor heat dissipation effect.
- The radiator shield net or the radiator core air passage is blocked by debris, resulting in poor heat dissipation.
- The belts of the water pump and fan are too loose or broken.
- The electric diaphragm pump is damaged, the fan blades are reversed or deformed, and the wind ring is damaged.
- The thermostat is damaged in the closed position of the main valve.
- Long-term overload operation of the engine and late fuel supply time, etc.
- Check whether a valve is installed at the outlet.
