Fitment: Fits selected models across Audi and Volkswagen. Confirm exact fitment before ordering.
Product Description
The Arrowhead Thermostat Housing is a key component in the cooling system of select Audi and Volkswagen vehicles. This part is responsible for securely housing the thermostat, ensuring the correct flow of coolant between the engine and radiator. Constructed from durable black plastic with robust mounting points, it is designed to withstand the heat and pressure cycles of modern engines.
This thermostat housing is compatible with various Audi and Volkswagen models. It is typically found in vehicles such as the Audi A3, Q3, and Volkswagen Golf VII, Caddy, and Tiguan, particularly those with 1.6 and 2.0 TDI engines. Always confirm your vehicle's model, year, engine size, and engine code before ordering to ensure a correct fit.
Common symptoms of a failing thermostat housing include coolant leaks around the housing area, engine overheating, fluctuating temperature readings, low coolant warning lights, visible cracks or damage to the housing, and persistent coolant odours. You might also notice frequent need to top up coolant or signs of coolant pooling under your vehicle.
If you observe any of these symptoms, it is important to inspect and replace the thermostat housing promptly. Over time, exposure to heat and pressure can cause the housing to warp, crack, or degrade, leading to leaks and cooling system inefficiency.
