Your Ford heater core keeps the inside of your car toasty and warm. A heater core is a series of coils attached to the radiator by hoses. Coolant flows from the radiator through the heater coil. The surface area on your core’s coils heats up, allowing hot air to be sucked into your car. You control the amount of heat that your Ford heater core releases into your car by adjusting the heat levels and blower levels on your temperature panel. Maintaining your heater core is relatively easy. Your Ford heater core will be automatically taken care of when you have your cooling system serviced. Consult your owner’s manual for your maintenance schedule. There are several indications that you might have a problem with your heater core. If you turn on your heater and your car just does not seem to get warm enough, you may have a heater core problem. If you turn on the heater and it just does not smell right, you might have a problem. Obviously, if you find coolant inside your car, you probably have a leak. When any of these problems occur, do not ignore them, particularly if you are coming up to the winter season. Having an effective heater is imperative for the comfort of you and your passengers.
