Coolant Expansion Tanks For Your Car

One of the lesser-known parts on your Audi Q3 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

 

If you notice any of these signs on your car it might be the expansion reservoir. Don't worry though as this Audi Q3 coolant expansion tank is the best price and quality online. We also sell many more car parts for your vehicle, so we encourage you to take a look if you need anything. What's more, if you order this product before 2 pm on a work day you’ll get free next day delivery.
