In vehicles, heat coils are often called heater cores.

Like the radiator, the heater core acts by removing heat from the engine.

A heater core is a radiator-like device used in heating the cabin of a vehicle.

Some of that water can be diverted through the heater core to give some engine heat to the cabin.

This can be thought of as a heater core filled with very cold gas, which cools rather than heats the incoming air.

The heater core is made up of small piping that has numerous bends.

If clogging occurs the heater core will not work properly.

Another possible problem is a leak in one of the connections to the heater core.

Willie saw a repaired heater core on the floor of the Bronco.

He put in the heater core in the Bronco, too.
