1964-1967 Pontiac GTO Radiator for LS and LT Engine Swaps
Swapping an LS or LT motor into your GTO chassis can create radiator clearance headaches that push coolant temps beyond safe limits. This 1964-1967 GTO Radiator 15.5 inch tall for manual transmissions delivers LS and LT compatibility by dropping into the stock A-Body mounts and aligning with factory hose outlets and the fan shroud without any cutting or grinding. Constructed from premium aluminum, the core resists corrosion while shedding heat rapidly under sustained load.
Seamless Fitment into 1964 to 1967 GTO Manual Transmissions
This radiator measures 15.5 inch tall to match the original core height, allowing it to drop into the stock mounts without cutting or grinding. By retaining factory hose outlet positions and fan shroud alignment, installation time shrinks and potential frame damage is avoided. The precise fit also upholds chassis integrity and maintains proper coolant flow as intended by Pontiac engineers. Owners can complete the swap with confidence, knowing the radiator integrates with minimal modification to the vehicle structure.
High Conductivity Aluminum Core Accelerates Coolant Dissipation
Constructed from high quality aluminum, the core excels at pulling heat away from LS and LT engines under load. Aluminum resists pitting and electrolyte damage, so the radiator remains reliable season after season. Its lightweight nature reduces front end mass, delivering subtle improvements in handling and balance. The tube and fin design amplifies airflow contact, stabilizing coolant temperature whether cruising the highway or pushing the engine on back roads.
Durable Finish Options Guard Against Corrosion
Choose between a classic bare aluminum finish that showcases weld detail or a black epoxy coating that shields against moisture and road debris. The epoxy layer bonds tightly under strict quality control, providing a barrier that fends off corrosion without hiding craftsmanship. Bare aluminum exposes the core to direct inspection, making it easier to spot damage or leaks before they escalate. Both choices deliver long service life and complement the aesthetic of a restored GTO front end.
