water temp gauge bad warning light

The water temp gauge bad warning list is very practical. Once the water circulation system is short of water, the temperature sensor is faulty, the antifreeze is too little, the water leaks, and the temperature is too high, the water temperature lamp will also start the alarm state and directly light the red light on the instrument panel. In this way, the driver does not have to go to the repair shop to check inside and outside. He can directly run to the water circulation system to find out the problem. Although there is no temperature prompt, the function of the water temperature lamp is significantly higher than that of the water temperature gauge .

When the water temperature indicator is on, first drive the vehicle to the roadside, and don't turn off the engine at this time, because the temperature of the piston, steel wall, cylinder, crankshaft and other parts will be too high, and the engine oil will become thin and lose its lubricating effect. If the engine shuts down at this time, the parts are in an expanded state, and the gap between parts is very small, some soft metals will fall off after shutdown, and some will even stick to the cylinder. The correct way is to keep idling, and then find a way to cool down. You can unscrew the water tank cover by a small crack, and then add cold water or antifreeze after the water vapor is slowly discharged and the pressure of the water tank is reduced .

The reason for the alarm of the automobile water temperature gauge is lack of antifreeze. The thermostat cannot be opened normally or is stuck. Or the pumping capacity of the water pump becomes poor, resulting in poor water circulation .

After the vehicle runs normally, the water temperature indicator is usually a blue light, and the blue light disappears. The surface water temperature is normal . The water temperature indicator turns red bad warning light , yellow or flashes to indicate that the water temperature is high. If the water temperature indicator still shows blue light, it indicates that the water temperature is low . Different models have different performance modes. The water temperature warning light can illuminate when the coolant temperature rises close to the boiling point (for example, 95-98 ℃) to attract the attention of the driver.
