Radiator 67-69 Firebird Camaro LS Double Pass

The PWR NORTH AMERICA Radiator 67-69 Firebird Camaro LS Double Pass is a precision aluminum cooling system engineered for classic F-Body muscle cars equipped with modern LS-series engines. This double-pass radiator delivers superior heat rejection compared to single-pass designs by routing coolant through the core twice, maximizing thermal efficiency in high-output LS swaps where factory cooling capacity falls short of contemporary engine performance.

Built from lightweight aluminum construction, this radiator features an integrated oil cooler and passenger-side inlet/outlet configuration optimized for 1967–1969 Firebird and Camaro engine bays. The double-pass core design significantly reduces coolant temperature cycling compared to traditional single-pass units, resulting in more stable engine temperatures under sustained acceleration and sustained track use. Aluminum construction keeps weight minimal while delivering the thermal performance LS-powered classics demand, and the natural finish allows integration with both stock and custom radiator shroud setups.

This radiator is purpose-built for builders executing LS engine conversions in second-generation F-Body platforms—the most common modern upgrade path for these classic American performance cars. The integrated oil cooler eliminates the need for auxiliary cooling plumbing and consolidates thermal management into a single core, simplifying installation and reducing overall engine bay complexity. At 42.33 lbs and measuring 27 x 13 x 38 inches, it fits within original radiator mounting points while providing cooling capacity that matches LS output levels ranging from stock 270 hp through modified variants exceeding 400 hp.
