1964-1967 Pontiac GTO Tempest LeMans Aluminum Performance Radiator. AT Cars w/o AC. This is the smaller 15.5 Inch core for cars without factory AC. This is our super duty model with 2 rows of 1.25 inch cooling tubes. This is the 66-67 version setup but will work in all 64-67 cars with an non AC support. Comes complete with dual 12 Inch electric fans and aluminum shroud. These COLD-CASE radiators are Tig welded 100 percent aluminum and absolutely beautiful. Don't buy a 3 or 4 row aluminum radiator! It doesn't cool as good as these oversize 2 row models. These radiators are original appearing and have the correct stamping. Once painted, you'd be hard pressed to find a difference over an original versus a COLD-CASE. 100 percent TIG welded All Aluminum Polished OE style tanks (2) 1.25 Inch Rows 16 fins per inch Corrugated fins that give more surface area and more thermal transfer Pressure tested For auto trans (auto-trans-cooler) Radiator Specs Core 15-1/2 Inch Width 25-1/4 Inch Overall Height 20-1/8 Inch Overall Thickness 6 Inch Upper Hose 1-1/2 Inch Lower Hose 1-13/16 Inch Tubes (2) 1.25 Inch Tubes Trans Lines 12-1/4 Inch
