oil temp gauge keeps dropping while stopping

1. Parking problem. Not to mention the problem of car parts, it may be because the parking position is an uphill or downhill, resulting in the car is not in a stable state. Then the fuel tank will naturally tilt. The tilt of the fuel tank will cause the data of the oil gauge to change. The real value of the oil gauge is to look at the change of the oil gauge when the car stops on the flat ground.

2.The oil tank leaks oil. It may be due to the low chassis of the car, which is scratched to the fuel tank by stones or roadblocks when driving on the road. Even if there was no problem at that time, gasoline would slowly seep from the scraped hole under the fuel tank when the car was parked smoothly. After a night, the value of the oil gauge will naturally decrease. In this case, we must pay close attention to the inspection and solve it in time to avoid potential safety hazards.

3. Even in cold winter, as long as the engine temperature rises, it will stabilize at a certain value and will not continue to decrease.

4. The normal working temperature of the engine is 86 degrees, and the temperature in the cylinder is as high as thousands of degrees. The surrounding air temperature has little effect on the engine temperature, and the instrument will not return to zero due to a few degrees below zero.

5. You can find the fault of the water temperature sensor. If the sensor is damaged, replace it directly.

How:

1. Warning signs must be placed after parking

2. Do not shut down the engine immediately if the water temperature is too high

Many drivers will shut down the engine immediately when the engine temperature is too high. In fact, this is wrong, because the water cooling system needs to be driven by the engine. Once the engine is shut down, the water pump has no power, and the coolant cannot be recycled, and all parts of the engine are in a high-temperature working environment, which can not play the role of cooling, and may damage the engine parts.
