Radiator for LS and LT Engine Swaps in 1964-1967 Pontiac GTO

Retrofitting an LS or LT motor into a 1964 through 1967 Pontiac GTO puts added demand on the cooling system, and this 15.5 inch tall radiator for automatic transmissions delivers reliable temperature control without altering the stock mounts. Each unit installs into the factory core support, preserving fan shroud alignment and correct hose angles for a straightforward fit. Made in the USA from polished aluminum, it offers either a raw metal sheen or black epoxy finish to match your restoration.

Direct Fit into Factory Core Support

Retrofitting an LS or LT motor demands precise alignment and this radiator drops into the original core support without cutting or trimming. Fanshroud alignment and hose angles remain exactly as the factory set them, eliminating the need for custom brackets or adapters. The 15.5 inch tall core sits in the stock mounts and holds the automatic transmission cooler lines in the correct position. As a result, installation is straightforward and many mechanics can complete it using common hand tools. This design ensures a seamless upgrade without altering the vehicle frame or firewall.

Superior Heat Rejection with High Quality Aluminum

Constructed entirely from high quality aluminum, this radiator excels at shedding heat to prevent engine overheating under demanding driving. The material offers natural corrosion resistance compared to standard steel cores, ensuring that coolant passages remain clear over many seasons. Its lightweight nature reduces front end load and preserves vehicle handling characteristics. Fast heat transfer from coolant to fins allows the engine to maintain stable operating temperatures even when pushing power limits. Engineers selected this alloy to balance strength and conductivity for optimal performance.

Choice of Finish for Restoration or Custom Builds

Owners can choose a polished bare aluminum finish for a classic engine bay shine or select a black epoxy coating for subdued appeal and extra protection. The epoxy finish adds a durable barrier against road salts and moisture without hiding the radiator's fin design. Polished aluminum blends seamlessly with chrome accessories and offers an authentic look on restored models. Each surface option is applied in house to ensure consistent coverage and uniform appearance. This flexibility lets installers match the radiator to any restoration theme or color scheme.

Built in the USA for Reliable Long Term Performance

Manufactured in the USA, this radiator undergoes strict quality control at every stage of production to deliver reliable performance and fit. Local production means faster response to design improvements and tighter tolerances for tank to core joints. Enthusiasts benefit from reduced lead times and the confidence of a product built to SAE guidelines. Over time, a proper fit and consistent cooling help maintain engine health and preserve resale value. Choosing a radiator made domestically supports local industry and underscores a commitment to craftsmanship.
