1966-1971 Olds 442 Aluminum Performance Radiator. For other A Body models, see GMA42A. 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 (2) 1.25 inch Rows All Aluminum Polished OE style tanks 16 fins per inch Corrugated fins that give more surface area and more thermal transfer Pressure tested For auto and standard trans (auto-trans-cooler) Direct fitment for 66-71 Olds 442 V8 Radiator Specs Core Width 28 inch Core Height 18 inch Overall Width 33.75 inch Overall Height 18.25 inch Overall Thickness 3 inch Upper Hose 1.5 inch Lower Hose 1.75 inch Tubes (2) 1.25 Inch Tubes
