chevy water temp gauge sending unit

The pointer of the Chevy water temperature gauge is inside the water temperature gauge. The scale unit of the water temperature gauge is centigrade. When the engine starts, the indication of the water temperature gauge shall not be lower than 50 ° C. when the vehicle runs normally, the normal indication of the water temperature gauge shall be between 70 ° C and 90 ° C. The effects of high water temperature on the engine are as follows: 1. The expansion of engine parts will reduce the clearance between the parts and aggravate the engine wear; 2. The viscosity of the engine oil will be reduced, which will lead to the aggravation of the wear of various components and the reduction of the service life of the engine; 3. If the cylinder gasket is damaged, it may cause the mutual flow of the water channel, oil channel and air channel on the cylinder gasket. The oil will flow into the water tank and the water will flow into the engine oil.

Chevy water temp gauge sending unit sensor is installed on the water channel and water tank of the car. 1. First, pull the wrench in front of the engine compartment cover of Chevrolet le to open the engine compartment cover of Chevrolet le. 2. After opening the engine compartment cover of Chevrolet Le wind, use the bracket to support the engine compartment cover. 3. After opening the engine compartment cover, the engine compartment water temperature sensor can be found at the position shown in the engine compartment.

As for the temperature sensor, the main function is to detect the temperature. When the vehicle has faults such as excessive load, water shortage, wrong ignition time, and the fan does not rotate, or the coolant temperature is too high due to long-term exposure in summer, the vehicle owner can know the temperature rise of the engine through this sensor.

The water temperature sensor of the car is broken, and the indicator needle of the water temperature gauge does not move and points to the highest position. It is difficult to start the cold car because the water temperature sensor is faulty. When the cold car is started, the temperature signal of the hot car is still displayed. The ECU can not get the signal of the rich mixture, and can only provide the lean mixture of the engine. Increased fuel consumption and unstable idle speed; It is difficult to accelerate. The accelerator is pressed to the bottom, and the engine speed cannot be increased.
