1964-1967 Pontiac GTO 15.5in Tall Radiator with Fans for LS and LT Swaps
When fitting an LS or LT engine into a 1964-1967 Pontiac GTO manual transmission chassis, ensuring adequate cooling while preserving underhood clearance can be a major concern. This 15.5 inch tall radiator matches original A-Body mounts for a direct installation that avoids rail trimming or bracket changes. Automatic dual electric fans switch on as needed to maintain airflow at idle and in traffic conditions. Constructed from an efficient aluminum core in the USA, it offers consistent heat dissipation and corrosion resistance for both street and track use.
Precision Fit for Original A-Body Mount Points
This radiator matches the factory 15.5 inch height on 1964 to 1967 Pontiac GTO frames so it installs without any rail trimming or bracket change. By aligning with the original mounting holes it preserves correct hose routing and ensures proper clearance under the hood. This accurate fit reduces installation time and minimizes the risk of coolant leaks that can arise from misaligned connections. Builders can rely on a seamless swap without altering the chassis or adding custom brackets.
Automatic Dual Fan System Ensures Reliable Cooling
Equipped with two high flow electric fans the assembly maintains steady airflow across the core even when the engine is idling or creeping in traffic. Each fan is wired to activate automatically based on coolant temperature so there is no need for manual controls or extra relays. The even airflow prevents hot spots and keeps operating temperatures stable during spirited street runs or track sessions. This plug and play wiring harness simplifies installation and delivers immediate performance without additional control modules.
Aluminum Core Offers Superior Heat Transfer and Light Weight
Built entirely from high quality aluminum the radiator core and end tanks deliver outstanding thermal conductivity while cutting overall weight compared to steel units. The fin and tube arrangement maximizes heat rejection whether cruising on the highway or pushing hard on the track. Customers can choose the classic bare aluminum finish for a vintage look or select the black epoxy coating for enhanced protection against moisture salt spray and road debris. Made in the USA under strict quality standards this core maintains performance and resists corrosion over many seasons.
