1964-1967 Pontiac GTO A-Body Radiator for LS and LT Conversions
Swapping an LS or LT V8 into a classic Pontiac GTO with a manual transmission often leads to radiator space issues that push coolant temps above safe limits, and this 15.5 inch tall radiator solves the clearance challenge by offering LS and LT compatibility within stock mounting locations. Its design drops directly into the original A-Body mounts found in 1964 to 1967 GTOs, aligning factory hose ports and preserving fan shroud position without cutting or grinding. Constructed from high quality aluminum, the core resists corrosion and pulls heat away rapidly under sustained engine load. Owners gain confidence knowing the unit maintains factory coolant pathways and preserves body structure for a straightforward installation.
Precision Drop In Fit for 1964-1967 GTO Manual Models
This radiator measures exactly 15.5 inch tall to mirror the factory core height, allowing a direct installation into the original A-Body mounts for vehicles equipped with a manual transmission. By retaining the stock hose outlet positions and fan shroud alignment, it eliminates the need for cutting or grinding frame rails or brackets. This precise fit preserves chassis integrity and maintains the cooling pathways as engineered by Pontiac, ensuring consistent coolant flow. Built in the USA, it also upholds the exacting tolerances required for a seamless swap that respects the vehicle's historic structure and performance.
Advanced Aluminum Core for Rapid Heat Transfer
Constructed from premium grade aluminum, the core excels at dissipating heat produced by modern LS and LT engines under sustained load. Aluminum resists corrosion and electrolyte damage far more effectively than traditional materials, so the radiator remains reliable season after season. Its tube and fin design maximizes surface area contact with airflow, stabilizing coolant temperature during highway cruises and spirited back-road runs alike. The lightweight nature of the material also reduces front-end mass, contributing to improved handling and weight distribution in the classic GTO chassis.
Corrosion Protection with Bare or Epoxy Coating
Choose a classic bare aluminum finish that exposes weld seams for easy inspection of potential leaks, or opt for the black epoxy coating to shield the core from road debris and moisture. The epoxy layer bonds under strict quality control, forming a durable barrier that guards against rust while preserving visual appeal. Bare aluminum offers straightforward maintenance and early detection of damage, while the coated option extends service life in harsh environments. Both finishes deliver long service life and complement the restored front end of any 1964-1967 GTO.
