1964-1967 Pontiac GTO Radiator for LS and LT Engine Swaps with Fans
When you install an LS or LT powerplant in a 1964 to 1967 Pontiac GTO A Body the stock cooling components fall short in stop and go traffic and sustained load. The 1964 to 1967 GTO Radiator 15.5" Tall Auto Trans with Fans delivers a drop in fit for the factory 15.5 inch core by matching frame rail mounts and transmission cooler ports without trimming or custom brackets. Its dual electric fans are mounted on a removable shroud to pull air evenly through the full aluminum core at low engine speeds, preventing hot spots, steam pockets and cavitation damage. Built in the USA with TIG welded end tanks and precision machined end pieces this radiator preserves underhood clearance, maintains steady coolant flow and endures repeated thermal cycles for dependable street and track use.
Precision Core Fit for 1964 to 1967 GTO A Body Applications
This radiator is engineered to match the factory 15.5 inch core opening on Pontiac GTO A Body frames from 1964 to 1967. It aligns exactly with the stock frame rail mounting points and automatic transmission cooler ports so you can install it without cutting sheet metal or fabricating brackets. By preserving underhood clearance and hood latch engagement, the design prevents interference with existing engine mounts and accessory drives. Installers benefit from reduced mock-up time and avoid potential leak points that can arise when custom modifications are made. The result is a seamless integration that supports higher coolant capacity and maintains optimal coolant flow under all driving conditions.
Balanced Airflow Management with Dual Electric Fans
The pair of high torque electric fans draws air uniformly across the entire aluminum core even at idle and slow speeds. Mounted on a removable shroud, the fans eliminate hot spots and steam pockets that can lead to cavitation damage in the pump and passages. With both fans operating at moderate power, overall noise and power draw are reduced while sustaining consistent temperature control in stop and go traffic or during spirited track use. Routine cleaning and maintenance are simplified by sliding the fan assembly off the core for easy access to fins. This balanced approach protects system components and extends service intervals without compromising cooling performance.
Robust Aluminum Construction with Customized Finish Options
Constructed entirely from high quality aluminum, the radiator features TIG welded end tanks and precision machined mating surfaces for a leak-proof seal and exceptional structural integrity. Aluminum's natural thermal conductivity enables rapid heat rejection while keeping overall weight low to preserve front end balance. You can choose a bright bare aluminum finish for classic underhood appeal or opt for a black epoxy coating that enhances corrosion resistance in harsh environments. Each unit is assembled in the USA under strict quality controls to ensure consistent fit and finish from one radiator to the next. The combination of durable materials and protective finishes delivers reliable street and track performance over repeated thermal cycles.
