how to install water temp gauge

• 2022-09-29

The automobile water temp gauge is installed on the instrument panel in the cab, and the live wire is connected to the water temperature sensing plug on the engine body. In this way, the engine temperature can be displayed in time. Installation of water temperature gauge for vehicle. Install the sensing plug in the upper water tank of the tractor, and then install the meter on the instrument panel in the cab of the vehicle.

There are generally two water temperature sensors, one is the sensor of the water temperature gauge, and the other is a wire, which is used to display the temperature of the cooling water or coolant on the water temperature gauge and adjust the oil supply during startup. The other is a sensor for cooling water or coolant, which is a two-wire sensor. The coolant sensor is used to control the electronic fan. The electronic fan will work when the temperature is high. The connection method of the water temperature sensor of Dongfanghong engine There are three lines of the water temperature gauge, including the main line and the auxiliary line, as well as a signal line. The signal line controls the grounding wire. After the power supply line of the water temperature gauge is connected, the signal line grounding meter will rise.

In general, except for some more advanced models, the thermometer can be said to be indicative, (such as blue and red) for example, only blue can be seen at 80 ° C and 90 ° C, while the added water temperature gauge can more accurately grasp the temperature of the cooling water in the water tank, which is directly indicated by a pointer or a number.

The water temperature indicator can not accurately display the engine temperature, which will make the driver judge the engine working condition incorrectly, which is not conducive to the correct use and maintenance of the engine. If there is a water temperature gauge, it can accurately display the engine water temperature, so that the driver can accurately judge the working state of the engine according to the change of the engine water temperature and make timely treatment. For example, if the engine is often at a high temperature, the driver will check whether there is a lack of coolant and whether the water tank is dirty. If you wait until the water temperature indicator is red, it will be too late. The engine is already in a boiling state, which has actually caused damage to the engine. So the water temp gauge is necessary to install.
