Denso heater core replacements in copper
HC Denso
We are getting more calls to help out the Motorhome owners with leaking aluminum Denso heater cores.
We will likely need a pattern to build from but we can help you out.
IF YOUR CORE HAS CRIMPED TUBES THAT SPIN WE WILL NEED YOU TO INDICATE THEIR FINAL POSITION. THEY WILL BE SOLDERED FIRMLY IN PLACE IN THE CONSTRUCTION,
We make to order and our build queue varies.
Made in the USA

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
Heater cores ~6 weeks
Model A and 32 Ford Street rods 6 weeks
Common street rods ~12-15 weeks
Tricky customs & complicated restorations ~16 weeks months
We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
