Feelin’ hot, hot, hot…the heater core

The heater core is located inside the passenger compartment of the vehicle, quite often very deeply buried inside or under the instrument panel, or behind some other type of interior trim panel. Some SUVs and vans have two heater cores, a front and a rear. Regardless of location, all heater cores look like mini radiators. Hot coolant flows through the heater cores’ internal tubes, and air from the blower fan moves through the heater core to warm the interior of the vehicle.
What could go wrong with a heater core?
Leaking or blocked heater cores are generally not repaired, since they are usually relatively inexpensive items. However, due to accessibility issues, a heater core replacement job is often extremely time consuming, and therefore costly, due to the amount of labor involved.
When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
