Radiator for LS and LT Swaps in 1964-1967 Pontiac GTO
Fitting an LS or LT engine between 1964 and 1967 in a GTO A Body with a manual transmission often reveals tight clearance around the radiator and hoses. This 1964 through 1967 GTO Radiator 15.5 inch tall designed for manual transmissions addresses that challenge by matching the original core height and dropping straight into stock mounts without cutting frame rails. It features an aluminum core that pulls heat rapidly under sustained load while inlet and outlet ports align with factory hose positions to preserve correct routing. Manufactured in the USA it also retains the original fan shroud location for efficient installation and reliable coolant flow.
Exact Fitment for 1964 through 1967 GTO A Body with Manual Transmission
This radiator is engineered to stand 15.5 inch tall to match the original core height found in Pontiac GTO A Body models from 1964 through 1967 equipped with a manual gearbox. It drops directly into the stock mounts without any need to cut or grind frame rails, preserving the chassis strength and keeping installation time to a minimum. Inlet and outlet ports align precisely with factory hose locations, which maintains the intended coolant routing and fan shroud position for reliable airflow. By delivering a direct fit, this unit eliminates guesswork and body modification, so owners can complete their LS and LT swaps without compromising structural integrity. The result is a seamless integration that feels and performs just like the factory part.
Rapid Heat Dissipation with Premium Aluminum Core
Constructed from high quality aluminum, the core employs a tube and fin design that maximizes surface area contact with moving air. Aluminum's excellent thermal conductivity allows it to pull heat out of coolant rapidly under sustained load, ensuring stable temperatures even during spirited driving or towing. Its lightweight nature reduces front end mass, which helps maintain the classic GTO's handling balance and steering response. Compared to traditional metals, aluminum also resists corrosion and electrolyte damage, so the radiator delivers consistent performance season after season. Together, these characteristics make it an ideal choice for modern LS and LT engines swapped into vintage Pontiac platforms.
Bare Aluminum and Epoxy Coating Options for Corrosion Protection
This radiator is available in a natural bare aluminum finish or finished in a durable black epoxy coating. The bare surface allows for quick visual inspection of weld seams and early detection of any developing leaks, while the epoxy layer forms a barrier against road debris, moisture, and salt. Each coating is applied under strict quality controls to ensure full coverage and adhesion, extending service life with minimal maintenance. Choosing the uncoated version offers a classic appearance that displays craftsmanship, whereas the epoxy variant delivers added resilience in harsh environments. Both finishes combine functional protection with an aesthetic that complements a restored GTO front end.
Manufactured in USA for Consistent Quality and Fitment
Every radiator is fabricated domestically using precision tooling and rigorous dimensional checks to guarantee consistency from one unit to the next. By controlling core assembly, port alignment, and welding processes in a single facility, quality remains uniform and repeatable. This local production approach not only supports faster lead times but also ensures that each radiator meets or exceeds the original factory specifications for fit and finish. Owners benefit from a component that integrates seamlessly into their project, backed by reliable craftsmanship and a commitment to long lasting durability. Investing in a USA built radiator gives classic GTO enthusiasts confidence in both performance and authenticity.
