"1955-1957 Chevrolet Tr-Five Aluminum Performance Radiator. V8 Position cars for mount Behind radiator support. There is not enough space to put a clutch fan on the front of a SB and still mount the radiator in the V8 position. There is a 6 blade stationary and 7 blade flex fan you can use though. 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 16 fins per inch Corrugated fins that give more surface area and more thermal transfer Pressure tested For manual/auto trans Direct fitment for 55-57 Chevy (V8 position mount) Old Part Number: RPE562 Radiator Specs Core Height 17 inch Core Width 22 inch Overall Height 23.5 To Cap Overall Width 23.5 inch Overall Thickness 3 inch Tubes (2) 1.25"" Tubes Upper Hose 1.50 inch Lower Hose 1.75 inch"
