1964-1967 Pontiac GTO A-Body LS and LT Swap Radiator 15.5in Tall with Fans
Enthusiasts fitting an LS or LT engine into a 1964 through 1967 Pontiac GTO manual chassis will find that this 15.5 inch tall radiator with integrated fans solves common clearance and alignment challenges of the swap. It retains factory core height and stock mounting points for a true drop in installation without rail trimming or custom brackets. Dual electric fans trigger when coolant temperature rises to maintain airflow at idle or in traffic, preventing localized hotspots and keeping temperatures stable. Made from aluminum for rapid heat rejection and corrosion resistance, this radiator preserves underhood clearance and hose routing for reliable street and track operation.
Exact Alignment with 15.5 inch Core and Stock Mounts
This radiator is engineered to match the original 15.5 inch core height and factory mounting points on the 1964–1967 Pontiac GTO A-Body chassis, ensuring a true drop in installation. By preserving the stock bracket locations there is no need for rail trimming or custom brackets, which saves time and reduces error. Hose connections follow the factory routing exactly, preventing interference with other underhood components and eliminating the common risk of coolant leaks from misaligned fittings. The result is a streamlined installation that maintains the integrity of the engine bay layout with no sacrifice in clearance or fit quality.
Automatic Two Fan System for Consistent Airflow
Equipped with two high flow electric fans, this assembly maintains airflow across the core even when the vehicle is idling or navigating stop and go traffic. Each fan engages automatically as coolant temperature rises, removing the need for manual switches or additional relays. This parallel operation eliminates localized hot spots and promotes uniform coolant temperatures during long highway runs or spirited track use. A plug and play wiring harness integrates directly into the existing electrical circuit, minimizing installation steps and ensuring reliable operation under varied driving conditions.
Aluminum Construction for Rapid Heat Dispersion
The entire core and end tanks are fabricated from high quality aluminum to maximize thermal conductivity while minimizing weight. A precision fin and tube design increases the surface area in contact with incoming air, enabling fast heat transfer even under heavy engine loads typical of LS and LT powerplants. Aluminum's natural resistance to corrosion prevents scale formation and pitting over time, extending intervals between service and preserving performance. The reduced front end mass also contributes to a more balanced handling feel without compromising structural durability.
Flexible Finishes for Protection and Style
Customers may choose between a classic bare aluminum surface or a durable black epoxy finish to suit their aesthetic and environmental needs. The natural aluminum option showcases the bright metallic luster, while the epoxy coating forms a water-resistant barrier against moisture, road salts and debris. Both finishes are easy to maintain with simple cleaning and offer long service life in humid or coastal regions. This choice allows builders to tailor the appearance of their engine bay without foregoing the corrosion resistance essential for lasting performance.
