1964-1967 Pontiac GTO LS and LT Swap Radiator with Fans for Auto Transmission
Fitting an LS or LT powerplant into a 1964 through 1967 Pontiac GTO A Body often stalls over cooling setbacks and clearance issues, yet this 17.5 inch Tall radiator for automatic transmissions solves both. The direct match to the factory core height installs into original mounting points without trimming or bracket changes. With dual electric fans that engage at low road speeds and an all aluminum construction for rapid heat transfer and corrosion resistance, coolant temperatures stay in check under city or track driving. This setup preserves under hood architecture and streamlines your swap process.
Precision Core Height Alignment for LS and LT Engine Swaps
Matching the original 17.5 inch core height is crucial when installing an LS or LT powerplant in a 1964-1967 Pontiac GTO A Body. This specific dimension ensures a direct fit into factory mounting locations, so no trimming of the radiator support or modification of mounting brackets is needed. By preserving the under hood geometry, the risk of coolant leaks and alignment issues is greatly reduced. Installers benefit from simplified alignment and reduced labor time, and the chassis remains unaltered for factory appearance and structural integrity. Such precision is particularly valuable in restomod builds where authenticity and functionality must coexist.
Dual Electric Fans Ensuring Consistent Airflow
Equipped with two high output electric fans, this radiator ensures steady airflow through the core at low vehicle speeds. When traffic slows or engine load increases, the fans engage to prevent heat soak and maintain coolant temperature within the optimal range. Their efficient blade design draws air evenly across the radiator surfaces, avoiding hotspots that can lead to thermal stress. Drivers experience consistent engine performance in stop and go conditions or spirited track sessions. This system supports both daily street use and aggressive driving without compromise.
All Aluminum Construction for Rapid Heat Transfer
Constructed entirely from quality aluminum, the radiator facilitates quick dispersion of heat from the coolant. Aluminum's high thermal conductivity allows the core to shed excess temperature more rapidly than conventional materials, keeping the engine running cooler under load. At the same time, its lightweight nature helps maintain balanced front to rear weight distribution in the A Body chassis. Corrosion resistance is inherent to the alloy, preserving flow capacity and extending service intervals. This combination of properties results in both improved performance and reliable durability.
Finish Options for Enhanced Corrosion Resistance
To suit different aesthetic preferences and environmental conditions, the radiator is available with a bare aluminum surface or a black epoxy coating. The coated version adds a durable barrier against road salt and moisture, which is ideal for climates where corrosion risk is high. The plain finish highlights the billet texture and simplifies inspection for potential leaks or damage. Both finishes are applied in the USA and meet rigorous quality standards. This choice allows builders to tailor protection and appearance to their own restoration or performance objectives.
