1964-1967 Pontiac GTO Tempest LeMans LS SWAP Aluminum Performance Radiator. For cars w/o AC.

This is a 64-65 style radiator but will work for those running a mild LS Swap engine on any 64-67 car without factory AC. For AC cars, see GPG22A-LS.

Another option for higher horsepower LS motors is to run the 66-67 version radiator with offset inlet/outlet positions. Run a 2 piece upper hose that goes to the drivers side inlet (use a 'T' fitting in between the 2 hoses for the steam port).

These COLD-CASE radiators are Tig welded 100% 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% TIG welded
-All Aluminum
-Polished OE style tanks
-16 fins per inch

-Pressure tested
