Aluminum Radiator GM 66-88 Cars

The Northern Radiator Aluminum Radiator for GM 1966–1988 cars is a purpose-built cooling solution engineered for classic muscle cars and street machines requiring reliable thermal management. With dimensions of 25.375 inches wide by 18.625 inches high and a 3.125-inch core depth, this aluminum radiator delivers efficient heat dissipation through all-aluminum construction—a critical upgrade for vehicles running modern ignition systems, higher compression ratios, or extended highway driving where stock cooling capacity falls short.

The radiator features driver-side inlet and passenger-side outlet configurations, allowing straightforward integration into existing cooling systems without extensive plumbing modifications. At 15.3 pounds, the aluminum construction reduces overall vehicle weight compared to traditional copper-brass cores while improving corrosion resistance and longevity. The natural aluminum finish resists oxidation and remains visible under the hood as a clean, period-correct appearance or functional upgrade depending on your build philosophy.

This radiator suits Chevrolet, Pontiac, Oldsmobile, and Buick applications from 1966 through 1988, covering the majority of second-generation muscle car platforms and early hot-rod restorations. Whether you're rebuilding a Chevelle SS, GTO, Cutlass, or full-size performance sedan, this radiator provides the cooling capacity needed for reliable summer cruising, weekend track use, or high-idle engine configurations. Mechanics and enthusiasts choose Northern Radiator for its engineering precision and bolt-in compatibility with original mounting points.
