The slow temperature rise of automobile water is generally caused by the failure of the cooling fan, because the cooling fan rotates the electronic fan according to the circuit control. If the cooling fan fails, the fan will continue to rotate, causing the temperature of water to rise slowly.
After finding out the reason for the slow temperature rise of vehicle water, we can raise the water temperature faster and save the time for hot vehicle. However, it should be noted that the lower the water temperature, the better, or the higher the better, and the water temperature also has a normal range; Generally, the water temperature is controlled at about 90 degrees, so you can check the temperature on the water thermometer.
