LS and LT Radiator for 1964-1967 Pontiac GTO
Swapping an LS or LT engine into a 1964 through 1967 Pontiac GTO with an automatic transmission demands a radiator that matches the factory dimensions and preserves original hose and bracket positions. It aligns with the stock shroud mounts and inlet outlets so installers can reuse OE hoses and hardware without trimming or relocation. Thanks to its 17.5 inch core height, this aluminum unit offers efficient heat transfer, reduced front end weight, and natural resistance to corrosion under spirited driving or stop and go traffic. Local fabrication in the United States ensures consistent dimensions, thorough quality checks, and reliable performance from first startup through long term use.
Exact Factory Core Height for Seamless Installation
The 17.5 inch core height matches the original radiator dimensions to keep coolant hoses, brackets, and the fan shroud in their stock positions. This precise fit removes the need for trimming or repositioning, preserving the engine block placement and driveline alignment. By maintaining the factory routing, installers avoid trapped air pockets that can cause local hot spots. The result is a straightforward installation with consistent cooling performance from initial startup through sustained use. This approach also preserves the classic under hood appearance of the GTO, maintaining a factory look that complements restoration efforts.
Premium Aluminum Body for Rapid Heat Rejection and Reduced Mass
Constructed entirely from premium aluminum, this radiator takes advantage of the metal's natural conductivity to shed heat from the coolant quickly. The internal tube and fin layout maximizes surface area in contact with moving air, ensuring stable temperatures during spirited runs or stop and go traffic. Aluminum also lowers weight at the front of the car, improving handling feel without sacrificing strength. In urban settings and highway cruising, drivers will notice more consistent coolant temperatures under varying loads. Over time, the metal resists corrosion and minimizes scale build up in the core, extending the interval between maintenance checks.
Coating Choices That Balance Protection with Heat Transfer
Drivers can opt for a bare aluminum finish to allow ambient air to contact the coolant chamber directly, maximizing thermal exchange. Alternatively, the black epoxy layer offers a moisture and debris barrier that guards against pitting and oxidation in humid or salted environments. The epoxy is applied and cured to create a uniform coating that adheres firmly to the surface, resisting chips and wear. Despite adding a protective layer, the finish has minimal impact on cooling efficiency and helps prevent the formation of corrosion over time. The black coating also complements painted or polished engine components, giving the under hood area a cohesive, refined look.
American Craftsmanship for Consistent Fit and Reliability
Each radiator is fabricated in the United States under strict quality controls to ensure consistent dimensions and performance across every unit. In process inspections verify core height tolerances, tank integrity, and weld strength before the final assembly stage. Local production also allows for rapid adjustments and precise material sourcing, avoiding the dimensional variations common in offshore manufacturing. This level of oversight delivers a radiator that fits 1964 through 1967 Pontiac GTO A Body installations without modification and provides dependable performance over the life of the swap project. Comprehensive documentation and customer support further streamline the process for professional installers and home builders alike.
