1987-2006 Jeep Wrangler 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 welded All Aluminum Polished OE style tanks 16 fins per inch Corrugated fins that give more surface area and more thermal transfer Pressure tested Direct fitment for 87-06 Jeep Wrangler Old Part Number: RPE991 Radiator Specs Core Height 18 inch Core Width 20 inch Overall Height 23 inch Overall Width 25.8 inch Overall Thickness 3 inch Tubes (2) 1.25 inch Tubes Upper Hose 1.25 inch Lower Hose 1.50 inch
