Speedway Motors WindChill™ Universal LS Swap 3-Row Aluminum Radiator Kit with Dual Fans and Shroud, 31x19 Double Pass Crossflow Design with Steam Port, LS Hose Fittings Included

Ready to run kit includes aluminum fan shroud, dual 10-inch or 12-inch fans, and mounting hardware. Stamped aluminum end tanks with high-flow 3-row aluminum core. Furnace brazed construction with TIG welded end tanks, no epoxy sealer or tank crimps/O-rings to fail. Available in three widths (28”, 31”, and 33”) to accommodate various core support openings. Dual pass cross flow radiator core to maximize coolant thermal transfer. Three rows of .790-inch core tubes for extra coolant capacity and more cooling fin contact. Approximate 17 percent increase in cooling system capacity over typical 2-row radiators. Radiators include integrated steam port and temperature sensor NPT thread fittings. Billet aluminum filler neck is stronger and seals better than cast filler necks. Features standard LS-spec 1.25” upper and 1.50” lower radiator hose fittings. Integral transmission cooler uses standard 1/2-20 inverted flare female (IFF) fittings. Keep Your LS Swap Build Cool Using Our Universal Fit Double Pass Aluminum Radiator Kit The LS engine has found its way under the hood of just about every make and model you can think of since it became the darling of the engine swap world. Compact, powerful, tons of upgrade and performance options, and most of all, easy on the wallet, the LS swap has become common place. The more interesting swaps require a little planning and fabrication to pull off a successful swap, but they quite often turn the most heads and are often the most talked about vehicles at a show. The thing is the LS cooling system can be a head scratcher for some. More so than fabricating a set of motor mounts even. The cooling system utilizes a surge tank setup and two or four steam port outlets from the cylinder heads. This complicates the cooling system design and often leads to overheating issues due to not fully understanding how the LS cooling system works in an LS swap environment

• HIGH-EFFICIENCY 3-ROW COOLING CORE: Features three rows of .790-inch performance cooling tubes for increased coolant capacity and thermal transfer, providing improved temperature control in demanding LS swap applications.
• UNIVERSAL LS SWAP FITMENT: Designed with standard LS 1.25-inch upper and 1.50-inch lower hose fittings, plus built-in steam port and temperature sensor NPT bungs to simplify plumbing and eliminate the need for adapters or custom hoses.
• DOUBLE PASS CROSSFLOW DESIGN: Coolant passes through the core twice for superior heat dissipation, reducing operating temperatures and improving efficiency during idle, cruising, and high-performance driving conditions.
• COMPLETE RADIATOR + SHROUD + DUAL FANS KIT: Includes fabricated aluminum end tanks, billet filler neck, precision-fit aluminum shroud, and your choice of dual 10-inch or 12-inch electric fans for maximum airflow and stable cooling.
• DURABLE ALL-ALUMINUM CONSTRUCTION: Fully furnace-brazed core and TIG-welded end tanks avoid epoxy and crimp failures, while the integrated transmission cooler with 1/2-20 IFF fittings supports factory or AN line setups.
