Radiator Alum. LS Swap 31.5in. X 19.5in.

The Radiator Alum. LS Swap 31.5in. X 19.5in. is a purpose-built cooling solution engineered for LS engine swaps into chassis originally designed for smaller powerplants. When you drop a modern LS V8 into a classic or mid-body vehicle, stock cooling systems fail catastrophically—this aluminum radiator bridges that gap. Built by BE-COOL RADIATORS, a trusted name among engine swap builders and performance shops, this unit delivers the thermal capacity required to keep your LS running cool under sustained load, whether on street duty or weekend track days.

Constructed from lightweight aluminum, this radiator maximizes heat dissipation while minimizing rotational mass—critical factors in swap applications where weight reduction affects handling balance. The 31.5-inch height and 19.5-inch width dimensions fit tight engine bay constraints common in LS swaps, allowing builders to work within existing hood and firewall clearances without major fabrication. Aluminum construction resists corrosion and responds faster to coolant flow changes than traditional copper-brass designs, maintaining stable operating temperatures during transient throttle events and reducing thermal stress on gaskets and seals.

This radiator suits anyone undertaking an LS engine transplant into pre-2000s American muscle cars, imports, or hot rods where modern cooling demands exceed original equipment capacity. The compact footprint works with both hydraulic and electric fan setups, offering flexibility in your cooling package design. Installation typically pairs with custom radiator mounts and modified piping, making this a centerpiece component in a complete LS swap cooling system rather than a bolt-in replacement.
