Radiator 68-72 Chevelle LS Double Pass

The PWR NORTH AMERICA Radiator 68-72 Chevelle LS Double Pass is a high-performance cooling solution engineered for classic Chevrolet A-Body vehicles equipped with LS-series engine swaps. This aluminum double-pass radiator delivers superior heat rejection compared to original equipment, making it essential for builders transitioning their 1968–1972 Chevelle to modern LS powerplants. The design accommodates both passenger-side inlet and outlet configurations, simplifying installation in factory core support locations while integrating an integrated oil cooler for comprehensive thermal management.

Double-pass core architecture forces coolant through the radiator twice, significantly increasing dwell time and heat transfer efficiency compared to single-pass designs. The aluminum construction offers a weight advantage over traditional copper/brass cores while maintaining superior strength and corrosion resistance. At 27 inches wide by 13 inches deep and 38 inches tall, this radiator dimensions fit the stock Chevelle radiator cavity without modification. The integral oil cooler eliminates the need for auxiliary cooling lines and mounts, streamlining the engine bay layout for LS conversions. Natural finish aluminum can be painted to match your engine bay aesthetic.

This radiator addresses a critical challenge in LS-swapped A-Body vehicles: stock cooling systems cannot handle the sustained heat output of modern engines in vintage chassis with minimal airflow dynamics. Enthusiasts performing full LS conversions depend on this kit to maintain stable operating temperatures during street driving, weekend cruises, and track events. The 42-pound assembly pairs with standard electric fans or traditional mechanical setups, offering flexibility in your cooling fan selection. Complete radiator-and-fan kit configurations provide plug-and-play integration for builders seeking minimal fabrication.

Classic Chevelle restorations with LS engine conversions have become increasingly popular among street rod builders and classic car enthusiasts seeking modern reliability without compromising vintage aesthetics. This radiator represents a purpose-built solution that respects factory dimensions while delivering contemporary cooling capacity. Its compatibility with GM A-Body 1968–1972 platforms and LS-series engines makes it the correct choice for serious restomod projects where thermal performance directly impacts engine longevity and drivability.
