Willys Harrison Heater Core

HC 39-41 Round H-139

$329.00

The Willys Overland uses the same housing as another Harrison heater core however it is badges as special at the top willys overland in the middle and heater on the bottom.

If you are a purist, you will probably want your round Harrison heater core restored. However many of you may just want your window clear of fog, your feet warm and your wife happy. Our re-designed heater core uses a better core design and a 12V SPAL fan.
