Mercedes 1971-1989 W107 Copper Heater Core
HC Mercedes 71-89 W107
This replaces series W107 Mercedes part 1078350201 . It has a tube and fin core with higher fin density and offset tubes for greate surface area. The tube bends are different than the 1078302645.
If you are searching for an obsolete, one-off or hard to find copper and brass heater core for your older 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." We require that you ship your pattern in.
Our build queue varies.
Made in the USA

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