1964-1967 Pontiac GTO Radiator for LS and LT Engine Swaps
Maintaining proper engine temperature in a 1964 to 1967 Pontiac GTO LS or LT swap requires a radiator that combines original A-Body mounting points with optimized cooling capacity. This 15.5 inch tall aluminum core model installs directly on manual transmission chassis without rail trimming or bracket changes, preserving underhood clearance while matching factory hose routing. Equipped with dual electric fans that activate based on coolant temperature, it sustains steady airflow at idle and in traffic conditions for consistent performance on street and track. Crafted in the USA from a corrosion resistant aluminum core, it delivers reliable heat transfer and durable service life under demanding swap applications.
Direct Alignment with Factory Mounting Points
This radiator installs directly on the original 1964–1967 Pontiac GTO frame without any rail trimming or bracket modifications. By matching the factory 15.5 inch core height and locating each mount point with precision, it preserves the correct hose routing and underhood clearance found in the stock A-Body layout. Builders benefit from a truly drop in installation that eliminates guesswork, custom brackets or the risk of misaligned connections that can lead to coolant leaks. The result is a straightforward swap process that saves time while maintaining the vehicle's factory geometry. This seamless fit ensures consistent performance and reliability in both street driving and competition use.
Dual Fan Assembly for Stable Operating Temperatures
Equipped with two electric fans, this system maintains continuous airflow across the core even at idle or in stop-and-go traffic. Each fan engages automatically when coolant temperature rises, so no additional relays or manual controls are required. The parallel operation of both fans prevents hot spots and keeps coolant temperatures within an optimal range during extended runs on road courses or daily commutes. Installation is simplified by a plug-and-play wiring harness that integrates directly with existing electrical circuits. Drivers can rely on consistent cooling performance without sacrificing engine bay space or adding complexity.
Optimized Aluminum Core Construction
Crafted from high quality aluminum, the radiator core and end tanks deliver exceptional thermal conductivity while reducing overall weight compared to steel units. The fin and tube design maximizes surface area for rapid heat rejection whether cruising at highway speeds or pushing the engine hard on track. Aluminum's inherent resistance to corrosion extends service life, ensuring long-term durability under harsh conditions. Built in the USA under strict quality standards, each radiator undergoes rigorous testing to verify its capacity to handle the heat output of LS and LT engines. The lightweight construction also contributes to improved front-end weight distribution and sharper handling.
Coating Selections for Durability and Appearance
Customers can choose between a classic bare aluminum finish or a protective black epoxy coating to complement their engine bay aesthetics. The bare finish highlights the raw aluminum, while the epoxy option adds an extra barrier against moisture, road salts and debris. Epoxy coating bonds tightly to the aluminum surface, reducing the chance of surface pitting or oxidation over time. Both finishes are easy to clean and maintain, allowing the radiator to look as good as it performs. Whichever option is selected, the protective treatment ensures reliable cooling and a polished appearance season after season.
