64-67 GTO w/AC HO/SD 1. 25in Radiator AT

The 64-67 GTO w/AC HO/SD 1. 25in Radiator AT by Cold Case Radiators is a high-performance cooling solution engineered specifically for classic GM A-Body muscle cars equipped with air conditioning and automatic transmissions. Owners of High Output and Super Duty engines require superior thermal management to prevent overheating during aggressive driving or when idling in heavy traffic. This complete radiator and fan kit provides the necessary heat dissipation capacity to maintain optimal engine temperatures even in demanding environments. By integrating a modern aluminum core into the classic chassis, you ensure your vintage vehicle remains reliable and road-ready for years to come.

Constructed from high-grade polished aluminum, this unit features a massive 3-inch deep core with oversized 1.25-inch tubes to maximize coolant flow and total surface area. The driver-side inlet and passenger-side outlet configuration aligns perfectly with original factory plumbing, while the integrated automatic transmission cooler makes it a versatile choice for factory-correct or modified builds. This kit includes a dedicated fan shroud assembly, which significantly improves airflow through the cooling fins at low speeds where traditional mechanical fans often underperform. The use of aluminum over traditional copper-brass components reduces front-end weight while offering far greater resistance to thermal stress and corrosion.

This 64-67 GTO w/AC HO/SD 1. 25in Radiator AT is designed for a direct-fit installation in 1966-1967 GM A-Body platforms, specifically catering to the Pontiac GTO and other performance-oriented models. Whether you are performing a comprehensive ground-up restoration or simply upgrading a weekend cruiser, this kit simplifies the installation process by providing a matched radiator and fan combination. It is a critical upgrade for vehicles running air conditioning systems, as the additional heat load from the condenser requires the increased efficiency found in these larger 1.25-inch tubes. Investing in this professional-grade cooling system protects your engine investment and ensures consistent performance throughout the peak summer months.
