Causes of oil pump failure

1. Oil quality problems. One of the oil quality problems may be the quality of the oil. Sometimes some impurities will enter the fuel tank, and these impurities will enter the oil pipe after entering. It may cause damage to the oil pump.

2. It may be because the temperature is too low, causing the oil to be frozen. Cause the oil pump to be blocked and burned out. Therefore, it is recommended that you add oil with a low freezing point when you use the parking heater, so that the oil will not be frozen.

3. Circuit problems, various car driving conditions are complicated, which may cause damage to the oil pump wires.

4. The installation angle will cause damage to the oil pump or heater failure.
