The Heater Core in Jeep Wrangler vehicles can be described as essential for heating the car as it is used to circulate extra engine heat in the vehicle. Looking somewhat like a miniature radiator, the core is managed with water and antifreeze, and the hot coolant from the car's engine circulates through this element to warm the cabin air. Some kind of heater cores could have temperature control like valves or doors, complex heater core would use electromechanical actuators for precise temperature control. it also supports in the dehumidification of a cooler in the sealed comfort of air-conditioned vehicles that reheat cool air. Problems exist in areas such as blockage, pin leakage and corrosion, and normally when repairing, it is usually associated with a lot of dashboard dismantling. Also in the air cooled engines, other means of heating can be applied but the associated hazards are also there.
