engine water temp gauge

If the actual water temperature of the vehicle is normal, driving will not be greatly affected without an engine water temp gauge. However, in some cases, it is necessary to know the water temperature, so it is necessary to install the engine water temp gauge. The engine water temp gauge is convenient for the driver to make driving judgment. From the generation of actual engine water temperature to the display of instrument water temperature, the water temperature sensor plays a major role. The water temperature sensor monitors the water temperature condition of the engine in real time, then converts the temperature signal into an electrical signal and transmits it to the engine computer or the body computer through a wire. After the computer is processed, it transmits it to the digital instrument through a wire. This is the water temperature information we see when driving normally (water temperature signal transmission process: water temperature sensor → ECU → engine water temp gauge → driver).

Therefore, the water temperature gauge only displays the water temperature information, and canceling it will not affect the vehicle. However, if the actual water temperature of the engine is abnormal, and the water temperature gauge is canceled at this time, the driving will be affected. Because the driver cannot receive the signal of abnormal water temperature, and cannot make corresponding driving treatment according to the actual situation, continuing driving will lead to engine damage and vehicle breakdown. Conversely, if the vehicle water temperature is normal and the cooling system is normal, canceling the water temperature gauge will have no effect.

And canceling the water temperature sensor has a great impact! The water temperature sensor not only provides water temperature information, but also plays an indispensable role in correcting the fuel injection amount and ignition advance angle of the engine. The ECU uses the received water temperature information to correct the ignition advance angle and change the fuel injection volume, so that the engine always works close to the ideal state. In addition, there are many parts that need to collect water temperature information, including the operation of the refrigeration air conditioner. If the water temperature is abnormal, the refrigeration effect of the air conditioner will be directly affected.

In a word, on the premise of ensuring the normal water temperature, the absence of a water temperature gauge will not affect driving; However, if the water temperature is abnormal and there is no water temperature gauge, the vehicle will be damaged and driving will be affected. So we always advise customers install an engine water temp gauge.
