HC 36-37 Round
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. The 1936-1937 round heater cores are designed to fit the Harrison 172 housing. Our re-designed heater core uses a better core design and a 12V SPAL fan. The thickness grows but we designed an interface that is not visible when installed inside the same round housing.
Our build queue varies but please allow at least 3-4 weeks.
Made in the USA
Please note: The flat housing in our photo does not come with the heater core and fan assembly. You will need to remove and tack solder or screw yours on (or send it in and we'll do it for you).
We make to order. Please allow adequate time for us to build.
