Fits 1997-2020 GM Gen III/IV LS Engines

---

Mr. Gasket Swivel Water Necks are great for engine conversion applications where engine/radiator inlet and outlet ports may be in different locations versus original equipment. The outlet rotates 360 degrees and has a 30 degree angle for versatility. Die-cast aluminum construction is strong, and durably resisting corrosion and is chrome plated for classic looks. It has a thick mounting flange to prevent warping and provide a positive engine coolant seal. Included stainless steel Allen head cap screws mount flush with the top of the flange to provide a smooth, custom look. Designed for use with 1/2 inch radiator hoses.
