1966-1967 Pontiac GTO Tempest LeMans Aluminum Performance Radiator. AT Cars w/o AC. This is the smaller 15.5 inch core for cars without factory AC.
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.

NOTES:
64-67 GTO Radiators: AC vs Non-AC Core Sizes
"Factory" AC vs non AC is the first question most people should consider. 64-67 Tempest, LeMans and GTO's had either an AC radiator support or a non AC support. The AC radiator support is 2" taller and can be identified easily. The only exception to this would be in 1964, GTO's all got 17.5”. The easiest way to find out what you will need is to measure your original radiator. If you have a 15.5” core, then you will need the non AC radiator regardless of whether you are installing aftermarket ac. If you have a 17.5" core, you'll need an AC radiator regardless of whether the car still has AC or not.
It is very common for Pontiac owners to swap out original motors for newer Pontiac motors like the 400, 428 or 455. Originally, all 64-67 A-body Pontiac radiators were downflow (meaning tanks on top and bottom). The 1964 and 1965 models have inlet/outlet both on the passenger side. The 66-67 models have the inlet moved to the driver side while the bottom outlet stayed on passenger side.
All filler necks for 1964-67 A-body Pontiacs were in the same spot except for 1965 non AC Tripower cars where the filler moved 4" to accommodate a different fan guard.
From the factory, most non AC cars had 3 row radiators and a 5 blade fan. The Tripower and heavy duty cooling option non ac cars got 15.5" 4 row radiators with a 7 blade fan and clutch. All AC cars got 17.5" radiators, 7 blade fan and clutch regardless of options.
Fan shrouds:
1964 cars did not use a fan shroud.
1965 AC cars had a metal fan shroud.
1966-67 AC cars had a plastic fan shroud that was essentially the same as the metal shroud.
All Cold Case radiators will allow for the reinstallation of these OEM fan shrouds.
