15.5 Inch Tall LS and LT Radiator with Fans for 1964-1967 Pontiac GTO A-Body
When converting a 1964 and 1967 Pontiac GTO A body to LS or LT power many builders discover the original cooling assembly struggles in stop and go traffic and under sustained load. This tall 15.5 inch core radiator with integrated electric fans features a drop in fit on factory frame rails and automatic transmission cooler ports with no trimming or custom brackets required. The pair of high flow fans draws air evenly through the all aluminum core at low speeds to prevent hot spots and guard against cavitation damage while sustaining proper coolant flow. Built in the USA with TIG welded end tanks and precision machined fittings this radiator preserves underhood clearance and holds up to daily street use as well as track duty.
Exact Core Fit for 1964-1967 Pontiac GTO A Body
This radiator is engineered to perfectly mate with the factory 15.5 inch core opening found on 1964-1967 Pontiac GTO A body frames, delivering a true drop in fit that eliminates the need for trimming sheet metal or fabricating custom brackets. By matching original frame rail mounts and transmission cooler ports, the unit preserves critical underhood clearance for hood latch alignment and accessory drives. The precision machined fittings ensure seamless integration with stock coolant lines while maintaining full capacity inside the core for consistent flow. Installers gain significant time savings by avoiding mock-up adjustments and potential leak points. The result is a clean installation that upholds the classic engine bay appearance and relies on exact geometry for reliable performance.
Optimized Twin Fan Cooling for Traffic and Track
The pair of high torque electric fans draws air evenly through the full aluminum core at low vehicle speeds, preventing localized hot spots that can lead to cavitation damage in water pump passages. Mounted on a removable shroud, the fans can be slid off for cleaning or service without disturbing coolant hoses or wiring, simplifying maintenance routines. Operating both fans at moderate power balances airflow delivery with charging system load, reducing in-cabin noise while sustaining stable temperatures in city traffic or spirited track use. This approach extends service intervals by avoiding temperature spikes and preserves pump life by maintaining steady coolant movement. The design safeguards critical engine components across varied driving conditions.
Durable Aluminum Construction with Finish Options
Crafted from uniform high quality aluminum, the radiator core and TIG welded end tanks deliver exceptional strength and leak-proof seals under repeated thermal cycles. Aluminum's superior conductivity enables rapid heat transfer, while its low mass helps maintain the front-end balance of the GTO chassis for improved handling. Buyers may choose a bare finish to highlight the craftsmanship of precision machined mating surfaces or specify a black epoxy coating for enhanced corrosion protection in harsh environments. Each assembly is built and inspected in the USA under strict quality standards to guarantee consistent fit and finish. This combination of material choice and protective coating ensures a robust cooling solution that stands up to daily driving and track duty alike.
