Expansion tanks for optimal engine fluid level maintenance

Durable fluid expansion tanks for longevity

Expansion tanks are essential parts of the engine cooling system, allowing you to control the coolant level and circulate it in the system. Thanks to them, the cooling system remains tight, and the pressure and temperature are maintained at the right level, which prevents the engine from overheating. In the Global Parts automotive store, you will find a wide selection of used car parts, including expansion tanks, perfectly matched to brands such as BMW, Audi , Mercedes, Volkswagen, Mini and others .

What are the functions of expansion tanks ?

Expansion tanks play a key role in the vehicle cooling system:

Coolant Level Control – Stores excess coolant that expands with temperature.
Pressure stabilization – They enable maintaining the appropriate pressure in the cooling system, which increases its efficiency.
Overheating Prevention – By circulating coolant through the expansion tank, the cooling system operates efficiently in all conditions.
Easy to refill – Reservoirs are usually equipped with a visible level gauge, making it easier to check and refill coolant.

Why is it worth taking care of expansion tanks ?

Damage or failure of the expansion tank can lead to cooling system problems and serious engine failures. Typical symptoms of failure include:

Coolant Leaks – Visible stains under the vehicle may indicate cracks or leaks in the reservoir.

Matching to the vehicle model – Each cooling system has its own specific technical requirements. At Global Parts you will find expansion tanks perfectly matched to BMW, Audi, Mercedes, Volkswagen, Mini and others .
Technical condition – Used tanks should be free from cracks, mechanical damage and signs of corrosion.
Equipment – Make sure the tank is complete, e.g. has a cap or integrated fluid level sensor.

Why choose used expansion tanks ?

Used car parts, such as used expansion tanks, is an economical solution that allows you to save money while maintaining high quality. By choosing used cooling system components, you gain:

Lower costs – Used tanks are much cheaper than new ones, but offer equally high quality.

Cleaning the tank – Regularly remove any sediment and dirt that may accumulate in the tank.
Avoid engine overheating – Make sure all cooling system components are in good working order to prevent excessive stress on the reservoir.
