Product Description
This Arrowhead thermostat housing is designed to manage coolant flow in the cooling system of select Audi and Volkswagen vehicles. It provides a secure connection point for the thermostat and coolant hoses, helping to regulate engine operating temperature efficiently. The robust plastic construction and integrated sealing features ensure a tight, leak-free fit when properly installed.
Compatibility includes various Audi and Volkswagen models, with primary application for Audi A4 B6 and B7 1.9TDI engines. Due to variations in model years, engine sizes, and codes, it is essential to verify your vehicle's details before ordering to ensure proper fitment.
