1966 to 1967 Pontiac GTO - Cold Case GPG34 - Radiator Options

Upgrade your 1966–1967 Pontiac GTO, Tempest or LeMans with a Cold Case GPG34-family aluminum radiator for cars without factory air conditioning. These versions use the smaller 15.5-inch core and OE-style stamped tanks for a factory-inspired appearance.

Choose your version

• GPG34: Manual transmission, polished aluminum finish.
• GPG34B: Manual transmission, powder-coated black Night Rider finish. Supplier specifies a non-air-conditioning radiator support and compatibility with the factory fan shroud.
• GPG34A: Automatic transmission, polished aluminum finish, with transmission cooler.

Matching fan shroud

Pair your radiator with Fast Monty's Garage dual 14-inch fan shroud for Cold Case GPG34. Designed for non-factory-AC applications, its fitment list names GPG34, GPG34B and GPG34A. Available in raw aluminum, matte black and custom-color options. Shroud sold separately; fans are not included. Compare radiator measurements with the dimension sheet in the shroud listing before ordering.

This shroud does not fit the GPG34AS wide-tube radiator with 1.25-inch tubes.

Fitment notes

For 1966–1967 Pontiac GTO, Tempest and LeMans applications without factory AC. Confirm the radiator support, transmission and mounting clearance before ordering. Do not select this smaller-core family solely by model year if your car has a factory-AC radiator support.

The supplier lists a 12.25-inch transmission-line measurement in all three descriptions without identifying its reference points. Confirm that measurement before using it for installation; its presence in a manual-version description does not establish that a cooler is included.

Legacy part number listed for both polished versions: RPE36L.

Warranty: Limited Lifetime Warranty.
