The Motorad 5004KT is a complete engine coolant thermostat housing assembly built for Ford 6.8L V10 applications, including Super Duty trucks, Excursion, and Econoline/E-Series vans from 1997-2019. This kit arrives with the housing, thermostat, and O-ring seal included, so there's no need to hunt down separate gaskets or components before installation. Constructed from copper, stainless steel, and steel, the assembly uses a mechanical disk-type valve that begins opening at 185°F (85°C) to help regulate coolant temperature as your engine warms. The offset design and air relief valve support consistent coolant flow through the cooling system. With two mounting holes for straightforward installation (mounting hardware not included), this standard-replacement grade assembly is designed to match original equipment specifications for Ford V10 applications listed in the fitment guide.
