autometer sport comp electric water temp gauge sender

The water temperature sensor is installed on the water channel and water tank of the vehicle. The autometer water temp gauge must work with sport comp electric water temp gauge sender unit . If the temperature sensor is broken, the indicator needle of the water temperature gauge will not move, and it is difficult to start the cold vehicle. The indicator needle of the water temperature gauge does not move and points to the highest position. Because the water temperature sensor is faulty, it still shows that the temperature signal of the hot vehicle is not indicated when the cold vehicle is started, and only the thinner mixture of the engine can be provided. 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.

A car with a thermal switch does not pass through the computer board, and the fan is directly driven by the thermal switch control relay. For vehicles without thermal switch, the temperature signal is transmitted to the computer board through the water temperature sensing plug, and the computer board controls the relay to turn on the fan . The connection of the thermal switch is very simple. It is equivalent to a switch, three wire plugs and one power cord. Some are positive stage control and some are negative stage control. When the temperature reaches 85 ℃, turn on the low-speed plug, and when the temperature reaches 93 ℃, turn on the high-speed plug.

After the water temperature sensor sender is broken, the indication of the water temperature gauge is abnormal and there is a phenomenon of swinging back and forth; In the winter morning, the pointer will respond after starting for a while (it used to be about 20 degrees below zero outside, and it takes 10 minutes to reach the engine operating temperature). Fuel consumption is significantly increased. There are two reasons for the low indication of the water temperature gauge. One is that the thermostat is damaged and keeps a large cycle. You can open the water tank cover of the cold car and start the motor car to observe the cycle speed. If the cycle speed is fast, the thermostat will fail. The other is that the water temperature gauge or the water temperature sensing plug is damaged. Can use our autometer sport comp electric water temp gauge sender for replacing.
