Expansion tanks: engine cooling system reliability

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:
