66-67 GTO Radiator w/AC AT Black

The 66-67 GTO Radiator w/AC AT Black from Cold Case Radiators is purpose-built for first-generation Pontiac GTO owners seeking modern cooling performance without sacrificing original aesthetics. Whether you're restoring a 1966 or 1967 GTO with air conditioning and automatic transmission, this all-aluminum radiator replaces aging copper-brass units that lose efficiency over decades of heat cycling. Muscle car enthusiasts and restoration shops trust Cold Case for solutions that blend reliability with correct fitment on classic American iron.

Constructed from premium aluminum with modern tube-and-fin core design, this radiator delivers superior heat transfer compared to original equipment while maintaining factory appearance with its black finish. The full-size core is engineered to handle the thermal demands of both stock and lightly modified engines, with integrated AC condenser provisions for vehicles equipped with factory air conditioning. At 26.5 inches wide by 26.5 inches tall, the radiator drops directly into factory mounting points without modification, and the automatic transmission cooler lines are correctly spaced and positioned for hassle-free installation. The lightweight aluminum construction—just 20 pounds—reduces overall vehicle weight while improving reliability through corrosion-resistant materials that won't develop the leaks or blockages common in aged original radiators.

GTO restorationists and street machine builders benefit most from this radiator, particularly when upgrading cooling systems on vehicles that will see regular driving or higher ambient temperatures. The black powdercoat finish complements both stock and custom engine bays, eliminating the need for additional dressing or modification. Installation is straightforward for anyone with basic mechanical skill—simply drain the old system, unbolt the original radiator, and bolt this unit in place using factory hardware. This radiator pairs perfectly with modern water pumps and thermostats as part of a comprehensive cooling system refresh, ensuring your 1966-1967 GTO maintains optimal operating temperature whether cruising at shows or tackling weekend drives.
