Seamless Alignment with 1964-1967 GTO Manual Transmission Frames
This radiator is engineered to match the exact dimensions of factory 15.5 inch core radiators used in 1964–1967 Pontiac GTO manual transmission models. By retaining original mounting points and frame clearance, it installs without trimming chassis rails or fabricating custom brackets. Builders benefit from reduced time in the garage and a precise fit that minimizes the risk of coolant leaks or hose misrouting. Whether you're completing a restoration or upgrading to a modern LS or LT engine, this unit streamlines the swap process and preserves factory under-hood geometry.
Premium Aluminum Core with Protective Finish Choices
Constructed from high-grade aluminum, the core offers exceptional thermal conductivity to rapidly transfer heat away from the engine. Its lightweight nature improves overall vehicle balance and contributes to quicker throttle response. Customers can select either a classic bare aluminum look for a period-correct appearance or a black epoxy coating that adds a layer of corrosion protection. Each finish is applied in the USA, ensuring uniform coverage and long-term resistance to road debris and moisture.
Dual Electric Fans Delivering Consistent Airflow
Equipped with two high-capacity electric fans, this radiator maintains optimal coolant temperature across all driving conditions. The twin fan arrangement directs airflow evenly through the core, preventing hot spots during low-speed city traffic or spirited track sessions. Automatic fan activation ensures temperature stability without driver intervention, reducing the chance of overheating under load. Preinstalled and wired, the fan assembly arrives ready for quick plug-and-play integration with existing wiring harnesses.
