If you've decided to add modern power to your ride using an LS series engine, this LS Swap Radiator Kit is the perfect way to protect your investment and ensure proper cooling system function. We wanted to offer a solution for the budget-minded builder that also kept aesthetics in mind. Instead of an inline hose adapter with an NPT bung for you to plumb in your own fittings, which can look like junkyard parts hacked together and is susceptible to leaks, we created a unique LS Steam Vent Radiator Hose Adapter. This adapter makes quick work of several LS swap radiator hose issues with one simple piece. It features one 1.25" end to match the water pump outlet, one 1.5" end to match the upper radiator inlet, an integrated streamlined 1/4" 90° hose barb fitting for the steam line, and a black finish to blend in with radiator hoses. The combination of this adapter with one of our professional-quality aluminum racing radiators means your search for an affordable and effective LS conversion radiator solution is over. LS Steam Vent Radiator Hose Adapter Features 1.25" end - matches water pump outlet size. 1.50" end - matches upper radiator inlet size. Integrated 1/4" 90° hose barb fitting for a streamlined look. Black finish blends in with radiator hoses. This LS1 Swap Radiator Kit features our single-pass universal aluminum radiator. These high-performance radiators feature furnace-brazed construction, two rows of large 1" aluminum tubes, billet filler necks and a maximum number of fins per inch for great heat transfer. They are not available with transmission coolers and they do not come with mounting brackets. Universal Aluminum Radiator Features: Driver’s side upper inlets. Passenger side lower outlets. All-aluminum, furnace-brazed construction. No cheap epoxy glue or crimped in gaskets. Maximum amount of fins per inch allows greater heat transfer. Billet filler necks. Available in 31" width
