1964-1967 Pontiac GTO LS and LT Radiator with Electric Fans
When dropping an LS or LT engine into a 1964-1967 GTO A-Body with an automatic transmission, fitting a radiator that preserves the original core height is critical. It is designed to match the factory 17.5 inch opening so hoses align without any trimming or bracket changes. Built from lightweight aluminum with dual electric fans, it sustains airflow at low speeds and rejects heat quickly under sustained load. Domestic fabrication ensures tight tolerances and consistent performance whether you are cruising city streets or pushing the car at the track.
Exact 17.5-inch Core Height for Precision Fit
Matching the factory 17.5-inch opening means the radiator drops directly into the original mounting points without trimming or bracket changes. Coolant hoses align naturally and maintain proper bend radii, preventing stress points that can lead to leaks. Retaining under hood geometry also preserves clearance to surrounding components, so there's no need to adjust condenser or fan shroud positions. This level of accuracy reduces trial and error during installation and keeps project timelines on track. Builders benefit from a seamless integration that upholds both function and factory styling.
Dual Electric Fans for Consistent Low Speed Cooling
Equipped with two powerful electric fans, this radiator sustains airflow when cruising in traffic or idling at stops. Each fan engages automatically at preset temperatures, drawing air evenly across the full width of the core to prevent heat soak during spirited driving or long waits at lights. The fan blades are shaped for maximum air movement with minimal draw on the alternator, protecting the charging system under load. A dedicated wiring harness with relay simplifies integration into the existing automatic transmission wiring. As a result, your LS or LT engine stays within optimal temperature ranges from boulevard cruises to track sessions.
Lightweight Aluminum Construction and Coating Choices
Constructed entirely from high quality aluminum, both core and tanks offer exceptional thermal conductivity that sheds engine heat almost instantly. The metal's natural corrosion resistant properties guard against pitting and internal scaling, while its low weight helps maintain a balanced front end. You can choose the classic bare finish to showcase the bright surface and ease leak detection, or opt for a black epoxy coat for added protection against moisture and road chemicals. Both finish options are applied domestically under strict quality controls to ensure uniform coverage and adhesion. This combination of materials and coatings delivers lasting performance in varied driving conditions.
