A heater core uses engine coolant to warm up the cabin of your Toyota 4Runner. The heater core is a radiator-like device, usually located under the dashboard. When the cabin needs to be warmed, a blower fan is activated, dissipating the heat from the heater core through ventilation, forcing the hot air into the cabin. Heater cores consist of a thin net of small hoses, usually made from aluminum or brass. Besides warming up the vehicle's interior , heating systems are usually used to defrost the windshield during the winter, allowing for good rearward visibility.
Some common symptoms can warn you that the heater core does not work properly: the windshield and other windows fog up, the engine runs hot and the cabin is cold, there are visible leaks of antifreeze (or you can smell a sweet antifreeze odor). If you experience a few or all of these symptoms, it's time to have the system checked. At our online store, we offer a large selection of Toyota 4Runner heater cores and related components, such as fittings and O-rings. Reliable and solidly built, our parts will deliver top performance for years to come.
