Car Heaters

If your car is overheating, you might have learned that you should open all the windows and run the heater with the fan on full blast. This is due to the heating system being a secondary cooling system that mirrors the vehicle’s primary cooling system. A heater core is a radiator-like system used to heat a vehicle’s interior. Hot coolant from the vehicle’s engine is routed through the core’s winding tube, which acts as a heat exchanger between the coolant and the cabin air.
