Product Description

This Moca Expansion Tank is a crucial component in your Audi or Volkswagen’s cooling system. Also known as a cooling water bottle, it acts as a reservoir for excess coolant, helping to maintain the correct pressure and fluid levels as your engine heats up and cools down. The tank features clearly marked minimum and G12 coolant indicators, ensuring you can monitor coolant levels at a glance.

This expansion tank is compatible with selected Audi and Volkswagen models. It is important to confirm your vehicle’s model, year, engine size, and engine code before ordering to ensure a correct fit. If you are unsure, contact MiMi Auto Parts for assistance.

Common symptoms of a failing expansion tank include visible coolant leaks, low coolant warnings, overheating, fluctuating temperature gauge readings, and coolant odours in the engine bay. You may also notice steam or bubbling near the tank, or cracks and discolouration on the plastic reservoir.

Replace your expansion tank if you see cracks, leaks, or if it cannot maintain the correct coolant level. Regular inspection is recommended, especially if your vehicle is experiencing cooling system issues or is over five years old.
