68-79 Nova BB Aluminum Performance Radiator And 16 Inch Fan Kit AT Transmission. Big Block version. Comes without brackets. For bracket version, see CHC11AK. 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 Fan Diameter 16 Inch All Aluminum Polished OE style tanks (2) 1.25 inch Tubes 16 fins per inch Corrugated fins that give more surface area and more thermal transfer Pressure tested For automatic transmission Direct fitment for 68-79 Nova w/ Big Block Old Part Number: RPE548ATFK Radiator Specs Core Height 16.85 inch Core Width 23 inch Overall Height 19 inch Overall Width 28.35 inch Overall Thickness 3 inch Tubes (2) 1.25 inch Tubes Upper Hose 1.50 inch Lower Hose 1.77 inch
