Coolant Expansion Tanks For Your Car
One of the lesser-known parts on your Audi A3 is the coolant expansion tank. This part is responsible for catching and storing coolant overspill from the vehicle's radiator. Your Audi’s coolant is designed to stop the car engine from overheating. It gets heated inside the radiator to its optimal working temperature. When this happens it expands and spills out. The expansion reservoir catches and stores it before it spills on the road.
How To Know If Your Expansion Tank Needs Replacing?
Some common symptoms for your Audi’s expansion tank failure include:
- The reservoir is constantly empty
- The engine overheating
- Coolant leaking out of the tank
