oil temp gauge reads high

• 2023-04-04

The reasons and solutions for the high oil temperature of the car are as follows:

1. The engine load is high: the waste heat generated is too much, which causes the oil temperature of the car to be too high. It may be due to improper use of gears or heavy load climbing of the vehicle, because the heat generated by the engine in a short period of time exceeds the heat dissipation capacity, resulting in an increase in oil temperature.

Solution: Cool down the engine.

2.The heat dissipation of the heat dissipation system is poor: the heat dissipation system fails, so that the excess heat cannot be dissipated. It may be due to the aging of the engine oil that the heat cannot be transferred out in time, or it may be that the cooling capacity is reduced due to insufficient coolant, or it may be that the vehicle speed is too low and the air volume through the radiator is insufficient, so that the heat cannot be diffused to the surrounding environment in time.

Solution: Go to a repair shop to repair the cooling system.

3. Insufficient or too much oil: This is a mistake that many drivers make when changing oil. Too much oil will cause greater resistance to the engine, and insufficient oil will affect lubrication and heat dissipation.

Solution: When changing oil, handle it strictly according to the scale of the oil gauge, and do not overdo it.

4. The piston ring is not tightly sealed: If the engine piston ring is not tightly sealed, the oil temperature will be too high. When the cylinders blow by, causing the crankcase to be over-ventilated, the oil is vented out of the engine.

Solution: Regularly check the tightness of the engine piston seals and cylinders.

5. The temperature of cooling water is too high: If the temperature of the water cooling system in the engine is too high, it cannot cool the engine parts in time and take away the heat, then the heated parts will indirectly cause the oil temperature to rise.
Solution: reduce the cooling water temperature.

6. Inferior engine oil: If you use engine oil that does not match the engine or inferior engine oil, it will also increase the internal friction coefficient of the engine, make the temperature rise more obvious, and cause the temperature of the engine oil to rise at the same time.

Solution: add better quality oil.

7. The cooling system leaks or the cooling water is insufficient, resulting in high oil temperature.

Solution: Go to a repair shop to repair the cooling system.

8. The indication of the water temperature gauge is inaccurate or out of order, resulting in high oil temperature.

Solution: Replace the water temperature gauge.

9. Radiator guard net or radiator core ventilation channel is blocked by debris, resulting in poor heat dissipation and high oil temperature.

Solution: Clean the radiator guard net or radiator core air duct.

10. The water pump and fan belt are too loose or broken, resulting in high oil temperature.

Solution: Replace the water pump and fan belt
