my oil temp gauge reads high when idle

• 2022-07-27

When parking, the car is stationary, the heat dissipation of the engine is not good, the oil temperature will be high, and the heat dissipation is good because of the air flow during driving. In this case, you'd better check whether the radiator fan of the engine water tank works normally, because the heat dissipation is not good at idle speed, so the engine temperature will be high.

Reasons for high idle temperature of the car:

1.Lack of coolant or leakage of coolant;
2.The outer surface of the water tank is dirty or the inside is dirty and blocked;
3.The thermostat is damaged;
4.The water pump is damaged;
5.The cooling fan and control system are damaged.

Solution:

1.Supplement the coolant;
2.When the water tank is dirty and blocked, it is recommended to replace it with a new one;
3.It is recommended to replace the thermostat with a new one;
4.It is recommended to replace the cylinder gasket with a new one. Idling is a kind of working condition of automobile, which refers to the engine running in neutral gear. The idle speed of the engine is called idle speed. The idle speed can be adjusted by adjusting the size of the damper. Idle speed means that the engine output does not work.

The normal oil temperature of a car is 70-90 ℃. The normal working temperature of the engine oil is mostly 70-90 degrees celsius, which will be higher in some parts, but most of it will not exceed the water temperature. And the speed is fast. The temperature will be higher than last year, reaching 100 degrees- 110 degrees; Up and down, but if it exceeds 120 degrees for a long time; You need to be aware of trends. The fault of high engine oil temperature is a comprehensive fault.There is scale or dirt in the engine block. The cylinder head and cylinder seat are damaged, connecting the cylinder with the water channel. At this time, not only the temperature is high, but also the antifreeze is accompanied by bubbles. Seriously, it will cause & ldquo; against water & rdquo; failure. Insufficient engine power
