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.

Common symptoms of a faulty thermostat housing include coolant leaks around the housing, overheating engine, fluctuating temperature gauge readings, low coolant warnings, or visible cracks and warping. You may also notice reduced heater performance or persistent coolant odours under the bonnet.

Replace the thermostat housing if you observe leaks, cracks, or if the housing becomes brittle over time. It is also recommended to replace this part during a thermostat replacement or major cooling system service to prevent future issues.

MiMi Auto Parts offers this Arrowhead thermostat housing with nationwide delivery across South Africa. Always confirm your vehicle's model, year, engine size, and engine code before placing your order for peace of mind and proper compatibility.
