Show original supplier description
The ACDelco ENG014 is a genuine, OE replacement thermostat and housing assembly designed for LS Gen 3 engines. This unit features an attached thermostat style and is engineered to be a direct fit for 1999 to 2006 model year Gen 3 Silverado, Camaro, and Corvette water pumps. This kit includes the essential components for a complete replacement: the thermostat housing, an OE-spec temperature thermostat, and a sealing gasket. It is manufactured by AC Delco, ensuring quality and compatibility with the intended applications. It is important to note that this thermostat and housing assembly will not fit Gen 4 truck water pumps with a large bolt-pattern or straight-neck design, nor will it fit LS3 water pumps. Always verify compatibility with your specific vehicle's water pump configuration.
