1984-1987 Buick Regal Grand National Aluminum Performance Radiator. AT Cars. This radiator has the correct oil and trans fittings used on the 86-87 models, unlike other reproductions on the market. You will need to modify part of the radiator support in order for this radiator to fit. See picture above.
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.
