HC 51 mercury
If you are searching for an obsolete, one-off or hard to find copper and brass heater core for your older vehicle 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." If we do not have a pattern you may need to ship yours in.
These are built to order and our build queue varies.
Made in the USA
We make to order. There is a nationwide labor shortage. Please allow adequate time for us to build. Build times vary between 15-18 and 24 weeks depending upon the item.
