aftermarket water temp gauge
Our auto gauge aftermarket water temp gauge has good quality and good price . During vehicle driving , the change of engine water temperature is directly related to vehicle speed , load and road conditions . The abnormal water temperature is directly related to the working condition of the electronic fan of the thermostat . In addition , if the water tank is blocked externally , the water temperature will be too high due to poor ventilation and heat dissipation .
In addition , if the pointer of the water temperature gauge is high or low , the problem of temperature display will not be ruled out , which is directly related to the working conditions of the water temperature sensor , water temperature gauge and related connecting circuits .
The indicator of the automobile water temperature gauge may be up and down due to thermostat failure. Just replace it . The water temperature can't rise to the middle line during driving . It can rise when there is traffic jam or idling , but it drops again when running . This is also a fault . The thermostat must be replaced . The function of the thermostat is to automatically adjust the amount of water entering the radiator according to the temperature of the cooling water , change the water circulation range , so as to adjust the cooling capacity of the cooling system and ensure that the engine works within the appropriate temperature range .
The water temperature indicator is one of the indicators on the automobile dashboard . This indicator lamp is used to display the temperature of the coolant in the engine . When the key door is opened , it will turn on for several seconds and then turn off during vehicle self inspection .
Its working principle is that a bimetal sensor switch is screwed into the cylinder water jacket , and this switch controls the red indicator light (water temperature indicator light) on the instrument panel . Within the normal operating temperature range , the switch arm contact is always open , and the indicator is not lit . When the water temperature exceeds the normal value , the switch arm contacts are closed to make the red light on . So , can add an aftermarket water temp gauge to check the water temp . It is more exactly.
