LS and LT Radiator for 1964-1967 Pontiac GTO A-Body
Owners fitting an LS or LT engine into a 1964-1967 Pontiac GTO A-Body manual chassis often hit interference between cooling components and stock mounting points that this 15.5 inch tall radiator with dual fans directly addresses. It retains the original core height and stock bracket pattern for a drop in installation that eliminates rail trimming and custom mounts. Automatic electric fans engage at idle to keep coolant temperatures in check during stop and go traffic while aluminum construction promotes rapid heat rejection and corrosion resistance. Hose outlets follow factory routing to prevent interference and simplify installation, ensuring reliable performance on street or track.
True Drop In Alignment for 1964 1967 GTO A Body
This radiator has been engineered to mirror the original 15.5 inch core height and match factory bracket locations on the 1964 through 1967 Pontiac GTO A Body chassis. By retaining stock mounting points there is no need for trimming frame rails or fabricating specialized supports. Hose outlets follow the factory routing precisely to eliminate clearance conflicts with steering components and brake lines. This precise fit reduces installation time and avoids common alignment errors that can lead to coolant leaks. The result is a seamless integration that preserves the original engine bay layout.
Automatic Fan System for Stable Coolant Temperatures
Equipped with two electric cooling fans, this assembly ensures continuous airflow across the core even when the vehicle is idling or creeping through traffic. The fans activate automatically based on coolant temperature and switch off when airflow is no longer required, eliminating manual control. A plug in wiring harness integrates directly into the existing circuit for a clean installation without extra relays or switches. Parallel fan operation removes hot spots and keeps temperature uniform across the entire core surface. Drivers benefit from consistent engine performance under every driving condition.
Aluminum Core and Tanks for Rapid Temperature Control
Constructed entirely from high quality aluminum, the radiator core and end tanks deliver outstanding thermal conductivity and rapid heat rejection. The fin and tube design maximizes contact between coolant and air to dissipate the heat generated by LS and LT engines. Aluminum's inherent resistance to corrosion prevents scale formation and pitting, extending service intervals and preserving flow efficiency. At the same time the lightweight nature of the material helps maintain balanced front end weight distribution. Builders will appreciate the combination of strength and thermal performance.
Coating Choices Tailored for Protection and Engine Bay Style
Customers can select either a bare aluminum surface or a durable black epoxy finish to suit their aesthetic and environment. The exposed aluminum option highlights the natural metallic sheen, while the epoxy layer creates a water resistant barrier against road moisture and airborne debris. Both finishes are simple to clean and require minimal maintenance to retain appearance and corrosion resistance. This choice allows enthusiasts to customize the look of their engine bay without sacrificing durability or heat transfer efficiency.
