The Heater Core in Ford Expedition vehicles will also have a significant responsibility of warming the interior of the car with the help of excess engine heat. Looking like an undersize radiator, the core is cooled by a water-antifreeze mix while hot coolant in the system flows through it. Calm air is circulated through the core by the fan which is found in the vehicle to heat the cabin air. There may be different heater cores which have valve or door for regulating the temperature or further pressing may include electromechanical actuators and thermistors. In air-conditioned vehicles, the heater core also plays the function of dehumidifier through reheating the cooled air. Some of the problems are clogging, leakage, and corrosion and usually need a lot of dashboard dismantling during the repair process.
