Who makes a heater core for the BMW?   We do.  If you are searching for an obsolete, one-off or hard to find copper and brass BMW heater core you are not alone and you may be in luck. We make our own cores and fabricate our own tanks so, naturally, we get asked to build custom heater cores or "small radiators."

Made in the USA 

We require the pattern be sent to us.  Each heater core is made to order, please allow adequate time for us to fabricate.

Present Lead times.

 If you need another heater core core for a different year or model ..You may mail your contact information, the heater core and assembly to:


We make to order. Please allow adequate time for us to build.

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

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.
