97-04 Corvette Radiator AT

The 97-04 Corvette Radiator AT from Cold Case Radiators is engineered specifically for C5-generation Corvettes equipped with automatic transmissions, addressing the cooling demands of high-performance engines during spirited driving and track sessions. As a mechanic who has rebuilt countless cooling systems, I can tell you that stock radiators on these cars often struggle with sustained heat rejection, especially when pushing the LS engine hard or during summer cruising. This radiator replaces the factory unit with a modern, higher-capacity core that maintains optimal operating temperatures under real-world and performance conditions.

Cold Case Radiators builds their units with all-aluminum construction, which offers superior thermal conductivity and durability compared to plastic-tank designs prone to failure. The all-aluminum core features efficient tube-and-fin design that increases surface area for heat dissipation, while the transmission cooler integration on this AT model ensures your automatic gearbox fluid stays within the ideal 180–200°F range—critical for transmission longevity and consistent shift feel. The compact footprint (measuring 22 inches wide by 34 inches tall) maintains OEM fitment while delivering approximately 30–40% more cooling capacity than the original equipment, without modification to engine bay geometry or hose routing.

This radiator is ideal for Corvette owners who drive their cars regularly in warm climates, tow trailers, or participate in autocross and road-course events where consistent cooling is non-negotiable. Installation is straightforward for owners with basic mechanical skills—the radiator retains OEM mounting points and hose connections, eliminating the need for adapter fittings or custom fabrication. Whether you're refreshing a high-mileage cooling system or upgrading a stock engine, the 97-04 Corvette Radiator AT delivers the reliability and thermal performance that separates casual weekend drivers from serious Corvette enthusiasts.
