1978-1988 GM G-Body Aluminum Performance Radiator. For Grand National radiator, see GMB57A. This radiator is specifically made for the 80-87 cars but will fit all G-bodies. This radiator has 1.25 inch upper hose inlet and 1.5 inch lower hose outlet.

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.
