Normally Expansion Tank is made by semi-transparent materials, such as plastic. The reason why use this kind material is that we can easily observed the liquid level directly through the box instead of opening the cap.
The operating principle of expansion tank is that, when people run cars, the temperature of the coolant circulating through the water jackets naturally increases which will increase pressure in the cooling system. When the pressure builds to a high enough point, the radiator cap allows that pressure to escape into the coolant reservoir through a small hose, called an overflow hose connected by the neck of the radiator to the expansion tank. Most of the coolant that is forced into the expansion tank returns to the radiator naturally after a few hours or when the engine is cold.
As engine coolant heats up, it expands. The Coolant Expansion Tank provides additional storage for the expanding coolant and is commonly the location where coolant is added to the engine.
Without expansion tank, cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. It is advisable to check expansion tank regularly.
We can provide all kinds of expansion tank and Brake Fluid Tanks with high quality and reasonable price. As we all know, expansion tank is a vital component in our car`s cooling system.
