Heaters

What does a heater do?

The heater coil is the source of heat that ultimately comes out through the car’s dash louvers. The heater coil acts like the evaporator, only using hot water from your engine to generate a hot coil. The heater coil is located in an enclosure called a heater box or plenum (heater-evaporator box). When the heater is turned on, the air that is forced through the heater coil is ultimately pushed through various ducts and louvers before entering the passenger compartment.

Due to market changes, we have made the hard decision to no longer offer restoration services. We do offer replacement upgrade kits and bolt in aftermarket kits to cover the void.
