water temp gauge 1995 gmc sierra

When the water temperature gauge of 1995 GMC Sierra pickup truck turns blue, it means that the water temperature is low. When the water temperature reaches above 40 ℃, the blue light automatically goes out. During cold start-up, the water temperature gauge will light blue, indicating that the optimal operating temperature has not been reached. When the water temperature rises after driving, the blue light will automatically turn off. It is recommended to warm up the vehicle for a few minutes when the blue light is on before driving, and turn off the blue light before driving. As long as the water temp gauge 1995 gmc sierra is normal within the normal scale range, the pointer enters the red area because the water temperature is too high. If the water temperature is too high for a long time, it will cause "boiling", that is, if the engine coolant boils, the water tank will expand and crack, and the engine will overheat and be damaged. However, generally speaking, the coolant (antifreeze) specified by the manufacturer can be used. Do not add water to the water tank casually.

If the water temp gauge 1995 gmc sierra shows that the water temperature is high, first check whether the water tank and condenser are too dirty so that the heat dissipation is poor. This phenomenon may also occur if the thermostat fails to open and close normally. If the water temperature sensor or the temperature control switch of the electronic fan fails, this phenomenon will occur. In addition, if the engine has too much carbon deposition or the air conditioning system pressure is too high, it may also lead to high water temperature when the air conditioning is turned on. Causes of high water temperature at high speed: it is caused by too much carbon deposits in the engine or early ignition time. When the engine has too much carbon deposits, the heat cannot be completely dissipated under high load and high speed, thus causing the water temperature to rise. An early ignition time will also cause the engine temperature to rise when running at a high speed. In addition, it may be caused by poor heat dissipation of the water tank. It is recommended that you check and clean the carbon deposits in the engine system, and pay attention to avoiding ultra-high speed and overload operation during driving; At the same time, correctly select the type of spark plug.
