The MotoRad 5500KT is a complete engine coolant thermostat housing assembly built to OE specifications for Volkswagen, Audi, and Seat models spanning 1998-2015, including Beetle, Golf, Jetta, A3, TT, and Leon variants with 1.8L turbo or 2.0L engines. Constructed from copper, stainless steel, plastic, and rubber, the kit includes the housing, thermostat, and required seal so you're not left hunting for extra parts at install time. The thermostat opens at 192°F for consistent, predictable coolant flow, while the offset design and air relief valve help ensure proper cooling system function. With a mechanical actuator and disk-style valve, this assembly is designed to replace your worn or failing housing with OEM-style form and fit. Whether you're dealing with overheating, coolant leaks, or erratic temperature gauge readings, this kit offers a straightforward, complete solution rather than piecing together individual components separately.
