aftermarket 52mm water temp gauge with alarm

• 2023-08-22

We provide aftermarket 52mm water temp gauge with alarm. Just as the car started, the water temperature alarm light came on, which is a self checking function of the car and is normal. When the car starts, many sensor lights will light up, and the dashboard should be visible. These lights will turn off after a few seconds, and after a long stop, due to the normal water temperature in the water tank being between 60 and 80 degrees, when the blue light comes on, it indicates that the water temperature is low. 

Cold start precautions: If the first attempt is unsuccessful, it is recommended to step on the fuel door during the second attempt, as the vehicle's engines are now electronically controlled. The engine computer will inject excessively rich mixture into the combustion chamber during cold start at low temperatures. 

When the aftermarket 52mm water temp gauge alarms, check the antifreeze, water temperature sensor, and coolant fan. Firstly, check if the antifreeze is low. Generally, if the antifreeze water bottle has a scale, check if it is below the scale. Then, check if the two fans in the water tank cannot turn. Then, drive the sensor to the repair area for inspection. If the fan does not move, first rotate the fan blades to see if the fan motor is stuck. Normally, it can be easily rotated. If there are no problems with the motor, it is necessary to check the fan fuse, which is one of the common causes, especially during high power consumption in summer. The failure of the thermostat is also a common cause of high water temperature. Once it fails, it will cut off the cooling water circulation. When there is a significant temperature difference between the two thick glue pipes above and below the water tank, it is a damaged thermostat that needs to be removed and replaced. This is usually handled by professional personnel. If the water temperature is slightly high during normal driving, it is important to pay attention to whether there is too much mud, cotton wool, or gravel on the surface of the water tank, which can cause a decrease in the heat dissipation capacity of the water tank. It is best to clean it thoroughly when washing the car. For older models, the high water temperature may be caused by the deposition of scale inside the water tank and engine, so it is necessary to go to a professional store for cleaning.
