The Motorad 379-180 is a complete thermostat housing assembly designed to restore accurate coolant temperature control on a wide range of GM V8 applications, including Corvette, Silverado, Tahoe, Escalade, and Express models from 1997-2003. Manufactured by an OE supplier to OEM specifications, this assembly features a copper case and wax-fill element that reacts quickly to changing coolant temperatures, helping maintain consistent engine operating temperature. The offset housing design and integrated air relief valve help simplify cooling system bleeding during installation, while the included OEM-style seal supports a proper seal against leaks without needing to source a separate gasket. With a 180°F rated thermostat and aluminum, copper, and steel construction, this assembly is built as a straightforward, complete replacement for demanding daily driving and towing conditions alike.
