Chevy 1936-1937 Standard 172 Heater Core
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.
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 .
We make to order. Please allow adequate time for us to build.
Build time estimates [Feb 2025]
Brass/Black Model Ts
Our longstanding foundry (supplier) closed and all production was shifted to a neighboring foundry. Apparently many of the closed foundry's workers were ineligible for rehire by the new foundry due to more aggressive immigration enforcement and the union has no employees to provide. As of 2-20-25, we should receive castings in March 2025 and can resume production then.
In the interim, we have been working with our one-off foundry to have pattern boxes made and these are trickling in in smaller batches and we will produce what we can.
Model As 5-6 weeks

We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
