If you are searching for an obsolete, one-off or hard to find copper and brass heater core for your 230SL, 250SL, 280SL - 113 Chassis Mercedes 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."  

This is important! Your heater core has an integrated valve.  The presence of the valve prohibits conventional testing e.g. the air pressure opens the valve.  We will test the heater core absent the valve and solder the tube (and valve) after testing. 

Should your valve be compromised the entire valve and/or require a rebuild kits they are available for ~250 and we are happy to install.  If that seems too much we have an alternative valve design at no cost.  If you do not tell us to keep it OE the we use our alternative design.

Our build queue varies.

Present Lead times.

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.
