PLEASE NOTE: We frequently find the 47-57 Harrison Heater cores installed in earlier truck. The 41-46 is SMALLER.
The center to center of the tubes is 6-1/2", tube length 5-1/2", core OD is 7", fan motor hole is 2-3/4"
If you are a purist, you will probably want your round Harrison heater core restored. However many of you may just want your window clear of fog, your feet warm and your wife happy. The 1941-1946 Harrison round heater cores for Chevy trucks look similar to our 47-54 Chevy Car and 47-57 Chevy Truck heater cores but the fans direction and center to center distance are different. The original donut design is difficult to make and the aftermarket donut core makers reflect that in their price. We re-designed the core and mounted a 12V SPAL pusher fan. We kept it all hidden inside the same round housing and did it so we would not break your bank.
Our build queue varies, but please allow 3-4 weeks for fabrication.
Made in the USA.
