Chrysler Pacifica Cooling System Switches, Sensors & Relays

All automobile systems that are responsible for energy transfer rely on switches, sensors, or relays, and the engine cooling system is no exception. Seemingly insignificant and sometimes overlooked, the switches and sensors it uses are actually crucial parts, as they are involved in system management. Coolant temperature sensors and switches are responsible for measuring the engine temperature: once the temperature reaches a specific threshold, the ECU gets this information and activates the radiator fan , which continues to run till the engine cools down and its temperature drops to a predetermined level. Without the data that the switches and sensors collect, the ECU wouldn’t be able to correctly regulate such functions as ignition and fuel supply.

So, when these parts are faulty or eventually wear out, your engine will stop function properly, and there will be risk of overheating. The cooling system parts are built to last for long years to come, but as they are exposed to the flow of coolant that contains aggressive chemicals, malfunctions are possible.
