Product Description

This Moca expansion tank is a crucial component in your vehicle's cooling system, designed to safely store excess coolant and maintain optimal pressure levels. It features a robust plastic reservoir with multiple hose connection ports, integrated mounting tabs, and fluid level indicator markings for easy monitoring. Proper function of the expansion tank helps prevent overheating and ensures the engine runs at the correct temperature.

This cooling water bottle is compatible with selected Audi and Volkswagen models, including popular vehicles such as the Audi A3, Q2, Q3, TT, and VW Golf VII, Passat, Tiguan, Touran, and T-Roc. Always check your vehicle's model, year, engine size, and engine code to confirm compatibility before ordering.

Common symptoms of a failing expansion tank include coolant leaks, low coolant warnings, visible cracks or swelling on the reservoir, engine overheating, and steam from the engine bay. You may also notice fluctuating coolant levels or a persistent coolant odour.

If you observe any of these issues, replacing the expansion tank promptly can help prevent further engine damage. Installation typically involves draining the coolant, disconnecting hoses, and fitting the new tank securely in place.
