One of the lesser-known parts on your Vauxhall Astra is the coolant expansion tank. This component is responsible for catching and storing coolant overspill from the vehicle's radiator. The coolant in your vehicle is designed to prevent the engine from overheating. As it reaches its optimal operating temperature, it expands and can overflow. The expansion reservoir collects this excess fluid and stores it safely instead of letting it spill onto the road.
How To Know If Your Expansion Tank Needs Replacing
Some common symptoms of an expansion tank failure on your Vauxhall Astra include:
The reservoir is constantly empty
The engine overheating
Coolant is leaking from the tank
If you notice any of these signs, the expansion reservoir may be the cause. Don’t worry, this Vauxhall Astra coolant expansion tank is an excellent value for money and offers strong reliability.
