1964-1967 Pontiac GTO A-Body LS and LT Swap Radiator 15.5 Inch Tall with Fans
When you fit an LS or LT motor into a 1964-1967 Pontiac GTO A body, the factory cooling setup can struggle in city traffic and under sustained load. This GTO Radiator 15.5" Tall (Auto Trans) with Fans offers a drop in solution that aligns with the original 15.5 inch core frame rails and automatic transmission ports without trimming or custom brackets. Its twin electric fans pull air evenly through the full aluminum core at low speeds to prevent hot spots and cavitation while maintaining steady coolant flow. Built in the USA with TIG welded end tanks and precision machined end pieces, it preserves underhood clearance while enduring repeated thermal cycles for reliable performance on street and track.
Precision Core Alignment for 15.5 Inch Radiator Opening
This radiator is engineered to match the factory 15.5 inch core opening on 1964–1967 Pontiac GTO A bodies, ensuring a direct fit with no sheet metal trimming or bracket modifications. It precisely aligns with the original frame rail mounts and automatic transmission cooler ports, preserving the underhood clearance required for hood latch engagement and accessory drives. By avoiding custom fabrication, installers save significant mock-up time and eliminate potential leak points that often arise from improvised brackets or altered mounting locations. The consistent mounting geometry also supports full coolant capacity within the core, maintaining steady flow and stable temperatures under sustained load or spirited driving. This focus on perfect fit translates directly into reliable performance on both street and track without compromising the GTO's classic engine bay appearance.
Efficient Dual Fan Airflow Management
The pair of high-torque electric fans draws air evenly across the entire aluminum core even at idle and slow speeds, preventing localized hot spots and steam pockets that can lead to cavitation damage inside the pump and passages. Fans are secured to a removable shroud, simplifying periodic cleaning and debris removal by allowing technicians to slide the assembly off the core without disconnecting coolant hoses or wiring. Operating both fans at moderate power reduces electrical load on the charging system and minimizes in-cabin noise, while still delivering ample airflow during stop and go traffic or hard track sessions. This balanced approach to cooling extends service intervals and protects engine components from overheating under a wide range of operating conditions. The design is optimized for longevity, ensuring that the system performs reliably through repeated thermal cycles.
Durable Aluminum Construction with Protective Coating Options
Constructed entirely from high-quality aluminum, the radiator features TIG welded end tanks and precision machined mating surfaces that deliver a leak-proof seal and exceptional structural integrity. Aluminum's natural thermal conductivity enables rapid heat rejection, while its light weight helps maintain front-end balance for improved handling. Customers can choose a bright bare aluminum finish to showcase the core's craftsmanship or specify a black epoxy coating that enhances corrosion resistance in demanding environments. Each unit is assembled and inspected in the USA, with strict quality control procedures ensuring consistent fit and finish from one radiator to the next. The combination of robust materials and protective coatings guarantees dependable street and track performance over thousands of miles and countless temperature cycles.
