Discover the Importance of the Coolant Expansion Tank for Your Audi Q3

The coolant expansion tank in your Audi Q3 plays a crucial yet often overlooked role in maintaining your vehicle’s engine temperature. This component captures and stores excess coolant that overflows from the radiator, preventing it from spilling onto the road. The coolant in your Audi Q3 is essential for keeping the engine from overheating. As it heats up to its optimal operating temperature, it expands, and the excess is directed into the expansion tank.

Signs Your Coolant Expansion Tank Needs Replacement

To ensure your Audi Q3 runs smoothly, it's important to recognise the symptoms of a failing expansion tank:

• The reservoir is frequently empty
