      Description

      Water Neck Swivel Solution. The Mr. Gasket LS Water Neck Swivel; 30-Degree Angle; Black is designed to provide flexibility in engine and radiator inlet/outlet alignments, especially during engine conversions. It allows the outlet to rotate fully for custom fitment, ensuring optimal coolant flow without compromising the setup. This feature is vital in applications where stock configurations do not match, preventing coolant leaks and improving engine cooling efficiency.

      Construction and Appearance. Crafted from die-cast aluminum, this water neck offers durability and resistance to corrosion. The satin black finish gives it a modern, custom look while the thick mounting flange prevents warping and guarantees a secure coolant seal. Flush-mounted stainless steel Allen bolts add to the clean, professional appearance.

      Installation. Installing this water neck is straightforward with no drilling required, designed to fit using existing mounting points. Its swivel design simplifies alignment, making the installation process easier even in complex engine swaps.

      Warranty. This product includes a manufacturer’s limited 90-day warranty for peace of mind.

      Application. Specifically fits 07-15 Sierra 3500 HD models. Note that this water neck is intended for 1997-2020 GM LS engines and does not fit 2013 and newer Gen V engines. 1997-2003 and 2009 engines require a 2004-2008 style thermostat to be compatible.
