Quality heat exchangers for any car work by exchanging hot and cold air in return for air-conditioning. Also known as radiators, heater-cores, condensers and evaporators, heat exchangers can take the heat from your engine, pass it through coolant and keep it at a certain temperature, so that you can have cool air when required. A heat exchanger can also heat air, using hot coolant to warm air from outside and allow you to heat your car when necessary.
Heat exchangers need to be cleaned periodically to prevent corrosion of the heat exchange equipment. Failure to do this can result in expensive repairs. Show Less
