LS and LT Radiator with Fans for 1964-1967 Pontiac GTO A-Body
When fitting an LS or LT mill into a 1964-1967 Pontiac GTO A Body the original cooling system often fails under higher heat loads and idling traffic. The 1964-1967 GTO Radiator 15.5" Tall Auto Trans with Fans offers a drop in fit into the factory 15.5 inch core location while matching frame rail and cooler line mounts with no trimming or bracket changes. Its dual electric fans draw air evenly through the full aluminum core at low speed and idle to prevent hot spots and cavitation. Assembly in the USA ensures consistent build quality and corrosion resistance for street or track use.
Precision Integration with Factory Core Dimensions
The 1964 to 1967 GTO Radiator 15.5 inch tall model delivers a drop in fit into the original core position on A Body frames. It aligns precisely with automatic transmission cooler lines and factory frame rails, eliminating the need for trimming or custom brackets. This exact match preserves underhood clearance, ensures proper hood latch engagement, and maintains the intended coolant routing. Engine swap installers can save hours on mock up and adjustment, accelerating the build process while reducing potential leak points in the coolant system. By replicating the factory mounting points, it supports higher coolant volume and prevents the original system from falling behind under heavy loads and in slow traffic. The result is reliable fluid flow and consistent temperature control across all drive conditions.
Even Cooling with Dual Electric Fans
Two high torque fans are mounted on an integrated shroud to draw air evenly across the full core surface. This balanced airflow prevents hot spots at idle and low speeds, avoiding steam pockets that can lead to cavitation and water pump wear. By keeping pressure stable throughout the coolant passages, the system sustains steady temperatures in stop and go traffic or on challenging roads. This arrangement reduces strain on the radiator and fan motor, as each fan can operate at lower speed settings while still delivering ample airflow. The removable fan shroud also simplifies access to core fins for routine cleaning and maintenance, extending the life of the core assembly for street and track applications.
Aluminum Core Strength and Protective Finishes
Constructed from high quality aluminum with TIG welded joints and precision machined end tanks, the core withstands vibration and repeated thermal cycles without warping. Aluminum's natural heat transfer properties allow rapid heat rejection while reducing overall weight to preserve front end balance. Customers can opt for a bright bare aluminum look or choose a black epoxy coat to enhance corrosion resistance and underhood appearance. Assembly in the USA ensures consistent build quality and adherence to exacting manufacturing standards. Both finish options resist road debris and environmental exposure, ensuring the radiator remains effective over extended use.
