Dodge Challenger Cooling System Switches, Sensors & Relays

While you are enjoying driving your Dodge Challenger, its engine works hard to generate hundreds of horsepower. In case it is not properly cooled, it will overheat leaving you stuck somewhere in the middle of nowhere. In fact, reliable operation of a number of your Dodge Challenger’s systems depends on engine coolant temperature. This makes switches and sensors of the cooling system very important components. These parts are threaded into coolant passages in which they are exposed to coolant and provide an input to the ECM (Engine Control Module) that in turn regulates the temperature of the engine coolant. Basing on the input received from other sensors, the ECM also regulates ignition, fuel, and other functions of a vehicle.

Coolant switches are applied when a simple on/off signal is required, but when the whole range of coolant temperature data is needed, coolant temperature sensors enter the game. A cooling relay is installed in carburetor vehicles. It supplies power to the heater grid, when a vehicle is cold, and is deactivated, when the engine reaches proper operating temperature. If your cooling switch, sensor, or relay is malfunction, don’t’ wait too long to replace it.
