water temp auto gauge

About the water temp auto gauge , let us talk about it . Sometimes , the water temperature of the car rises slowly. The reason is usually that the thermostat is damaged and the thermostat cannot be closed, or the cooling fan is in a normal running state due to failure. When the thermostat fails to close the valve, the coolant is always circulating, and the water temp auto gauge temperature of the car will drop quickly. If the cooling fan keeps running due to failure, the water temperature of the car will also be low.

The way to deal with the low water temp auto gauge temperature of the car is to first check whether there is a problem with the radiator, such as whether the shutter is blocked, whether the fan blade is deformed, and whether the water temp auto gauge sensor and circuit are short circuited. The thermostat can be disassembled and inspected, and put into water with different water temperatures to observe its opening. If it cannot be opened and closed normally, replace the thermostat.

Large circulation refers to the route of coolant flow when the thermostat is opened. Small cycle refers to the route of cooling flow when the thermostat is not opened. The low water temp auto gauge temperature of the car is also due to the failure of the cooling fan. For the electronic fan, the circuit fault causes the electronic fan to rotate normally . For silicon oil fan, the damage of silicon oil clutch will also cause the fan to rotate normally. These faults will cause low water temperature.

The thermostat is a component that automatically acts as a valve according to the engine water temperature. It is generally installed at the outlet of the radiator and the inlet of the water pump. When the coolant temperature is low, the thermostat blocks the low temperature cooling water from the radiator so that it cannot enter the engine water jacket, and the water temperature in the water jacket can rise quickly, which is often called a small cycle.

If the thermostat fails, the valve cannot be closed, and the coolant is always circulating, the engine water temperature may be too low. Or some cars simply remove the thermostat to reduce the temperature when the water temperature is high in summer, so the engine water temperature will be very low.
