LS and LT Radiator with Fans for 1964-1967 Pontiac GTO Manual Transmission
When swapping an LS or LT engine into a 1964-1967 Pontiac GTO A-Body with a manual transmission, tight radiator clearance often forces custom trimming or bracket modifications. This 17.5 inch tall radiator with factory installed dual fans aligns precisely with the original core opening and clears steering and gearbox linkages to avoid extra work. By securing the unit to the stock mounts it delivers a direct drop in fit while maintaining correct coolant line routing and reducing vibration that can lead to hose wear. Aluminum construction sheds front end weight for sharper steering response, resists corrosion over many thermal cycles, and keeps coolant temperatures steady whether cruising city streets or pushing hard at the track.
Precision 17.5 inch Core Fitment for Smooth Installation
This radiator matches the exact 17.5 inch height of the original A-Body core opening, eliminating the need for cutting or custom brackets. By clearing steering linkage and manual gearbox housing, it preserves factory coolant hose routing and prevents rubbing or kinks. Mounting securely to the stock points also reduces vibration that can lead to premature hose wear. Uniform core seating promotes even coolant distribution across every tube row, delivering consistent heat rejection whether idling in traffic or pushing the engine under load.
Premium Aluminum Structure for Weight and Heat Control
Constructed entirely from high quality aluminum, this radiator sheds unwanted mass from the front end to sharpen steering response and balance. Aluminum's natural corrosion resistance helps the core fend off moisture and road chemicals, extending its service life through repeated thermal cycles. Its excellent conductivity draws heat from the coolant quickly and transfers it to incoming air without warping at high temperatures. This marriage of low weight and structural toughness provides both durability and efficient temperature management on street drives or at the track.
Integrated Dual Fan Design for Reliable Airflow Management
Equipped with two factory installed electric fans, the assembly directs airflow across the full face of the core to eliminate hot spots and maintain uniform cooling. Fan operation is tied to coolant temperature or engine load, so engagement happens automatically without extra wiring or brackets. At low speeds or during idling the fans spring into action to prevent spikes in coolant temperature, while sustained fan output at higher engine demands keeps heat in check. This plug-and-play approach ensures dependable performance in stop-and-go traffic or spirited runs.
Bare Aluminum Versus Black Epoxy Finish for Lasting Protection
Builders can choose the clean appearance of raw aluminum or opt for a black epoxy coating that adds a durable barrier against moisture, road debris, and corrosive chemicals. The epoxy layer adheres tightly in a controlled domestic process to avoid flaking and maintain excellent thermal conductivity. Both finish options preserve the radiator’s core shape and performance through years of use. This flexibility lets enthusiasts align appearance and corrosion defence without compromising cooling efficiency.
