17.5-inch LS and LT Radiator with Dual Fans for 1964-1967 Pontiac GTO A-Body
Swapping an LS or LT engine into a Pontiac GTO A Body from 1964 through 1967 with an automatic transmission often reveals tight clearance spaces around the radiator core area and can strain cooling capacity. This 17.5 inch radiator with dual electric fans is designed to fit directly into the original core opening without any trimming or bracket modifications. By preserving the factory core height, coolant hoses align naturally and maintain under hood geometry for reliable operation on both street and track. Constructed from lightweight aluminum in the USA, it provides consistent airflow at low speeds and rapid heat rejection under sustained load.
Exact 17.5 inch Core Height for Plug and Play Fit
Matching the factory 17.5 inch core height eliminates guesswork and keeps the radiator within the original mounting points so no trimming or bracket modification is required. This precision fit preserves under hood geometry and ensures all coolant hoses drop into place without stretching or kinking. Installers can align the radiator and condenser exactly as designed by the factory, which reduces the chance of coolant leaks and avoids interference with other swap components. The drop-in nature of this radiator speeds up project timelines by removing trial and error steps and gives installers confidence in a clean, correct fit every time. Maintaining factory styling also benefits restoration builds where authenticity is as important as performance.
Dual Electric Fans Deliver Consistent Low Speed Airflow
Equipped with two high output electric fans, this radiator maintains airflow even when the vehicle is creeping through traffic or idling on a hot day. The fans engage automatically at defined temperature thresholds to draw air evenly across the full width of the core, preventing heat soak during spirited driving or extended stops. Their efficient blade geometry maximizes air movement while minimizing draw on the electrical system, which helps protect alternator life. A dedicated wiring harness with relay is included for straightforward integration with most automatic transmission swap plumbing and factory wiring. Consistent cooling under varied conditions ensures your LS or LT engine runs within optimal thermal limits from city streets to track days.
Aluminum Construction for Rapid Heat Rejection and Durability
Crafted entirely from high quality aluminum, both core and end tanks benefit from excellent thermal conductivity that sheds engine heat almost instantaneously. The lightweight structure reduces front end weight while resisting corrosion thanks to aluminum's natural alloy properties, which slow down pitting and internal scaling over time. Builders can choose a bare aluminum finish to showcase the bright metal surface and make visual leak checks effortless, or opt for a black epoxy coating for added protection against road salt and moisture. Both finish options are applied domestically under strict quality standards, ensuring uniform coverage and adhesion that lasts through seasons of driving.
Domestic Manufacture Ensures Precise Quality and Reliability
Every radiator is made in the United States in production facilities that enforce tight tolerances and rigorous inspection protocols. Dimensional checks confirm core height, tank alignment and weld integrity on each unit before it leaves the factory, reducing fitment surprises at installation. Consistent manufacturing processes translate into reliable performance right out of the box and fewer callbacks for fit or function issues. In addition, supporting local fabrication provides faster lead times for replacement parts or custom core upgrades, giving enthusiasts and professional builders peace of mind that service and support are always available.
