1970 plymouth roadrunner water temp sending units sensor is on the water channel and water tank of the car. The interior of the vehicle water temperature sensor is the vehicle water temp sending units . The lower the temperature, the greater the resistance . On the contrary , the smaller the resistance is, it is installed on the water jacket of the engine cylinder block or cylinder head , contacted with the cooling water, and then the temperature of the engine cooling water is measured . The electronic control unit measures the temperature of engine cooling water according to this change . The lower the temperature, the greater the resistance. On the contrary, the smaller the resistance . The electronic control unit measures the temperature of engine cooling water according to this change as the timing adjustment number of fuel injection and ignition. Know the current running condition of the vehicle , its termination or movement , or how long it lasts through the engine water temperature .

1970 plymouth roadrunner water temp gauge is also an important indicator to reflect the engine power condition. The 1970 plymouth roadrunner engine water temperature is also the engine coolant temperature . If the water temperature is high or low, and the pointer is unstable, it indicates that there is abnormal condition in the vehicle cooling system. Because the 1970 plymouth roadrunner water temp sending unit is installed on the water jacket of the engine block or cylinder head and directly contacts with the cooling water to measure the temperature of the engine cooling water. If the 1970 plymouth roadrunner water temp sending unit fails or fails, and the engine ECU detects that the output signal of the water temperature sensor is not credible, it will intervene in the use of alternative values, which is also for the purpose of protecting the engine , resulting in the unstable pointer of the vehicle water temperature gauge, At the same time , it will also be accompanied by difficulties in cold start and speed increase. The thermostat and the electromagnetic fan control the temperature , the water temperature sensor sends the signal to the computer, and the computer controls the electromagnetic fan . Generally , the high water temperature alarm lamp installed on the water temperature gauge is judged and controlled by the water temperature sensor.
