We’re here with a replacement 3-Core radiator for your ’64 through ’66 Mustang. This 3-Row Radiator will fit all ’64 through ’66 V-8 Mustangs. The third row will give you additional cooling over the standard two-row design. It has an inch and a half inlet, one and three-quarter inch outlet, fittings for your automatic transmission cooling lines, new pecock, and a braided drain hose as well. It’s going to install just like the factory does using a flange mount. Our 3-Row Radiator is an excellent choice if you’re looking for a little extra cooling for your Mustang, but want to keep that original look.
I replaced my stock 2-row radiator with this 3-row. It's a little beefier and does a great job keeping my fastback cool in the summer, especially when coupled with a thermal clutch fan. I prefer the stock look to the aluminum radiators.
