Cold Case Radiators CHI566A Features:
1966-1967 Chevy Impala Aluminum Performance Radiator. 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 weldedAll AluminumPolished OE style tanks(2) 1.25 inch Tubes16 fins per inchCorrugated fins that give more surface area and more thermal transferPressure testedFor auto/maunal transDirect fitment for 66-67 ImpalaRadiator SpecsCore Height 17.5 inchCore Width 25.1 inchOverall Height 23.5 inchOverall Width 28.75 inchOverall Thickness 3 inchTubes (2) 1.25 inch TubesUpper Hose 1.50 inchLower Hose 1.77 inchOld Part Number: RPE566Will fit in a 1961-1965 impala as well. Water neck and upper hose needs to be swapped for a 66-68 style to fit. This option is a good one for those looking for maximum cooling as upper LH and lower RH inlet/outlet is much more efficient than upper and lower being on the same side.Part TypeRadiator
