Coolant Expansion Tank Reservoir With Sensor Cap Not Included for Audi 2016-2023 Q7 And 2019-2023 Q8
Replace your Audi Q7 or Q8’s aging coolant expansion tank with this 100% new reservoir, crafted to fit 2016–2023 Audi Q7 models and 2019–2023 Audi Q8 models. Designed to OEM standards, this tank includes a coolant level sensor and is offered without a cap, making it a straightforward, direct replacement that keeps your cooling system accurate and leak-free.
The expansion tank plays a crucial role in the cooling system by storing excess coolant as the engine heats up and returning it when needed. With the built-in coolant level sensor, you’ll get accurate readings on your dashboard, helping you spot low-coolant issues before they lead to overheating. Its robust plastic and rubber construction stands up to heat, vibration, and the rigors of daily driving, ensuring reliable performance long after installation.
