The expansion tank is a critical component of an automotive cooling system, typically made of semi-transparent plastic. It is connected to the radiator overflow tube via hoses, providing a buffer space for the cooling liquid that expands when heated and automatically compensating for cooling liquid loss in the system.

Its core functions include:

• Pressure Balance: Absorbing volume changes (expansion and contraction) of the cooling liquid caused by temperature variations, maintaining stable system pressure within the range of 0.9-1.5 bar.
• Deaeration: Separating and discharging bubbles in the cooling system to prevent air lock and water pump cavitation, thereby reducing the risk of cylinder liner cavitation erosion.
• Liquid Level Compensation: Automatically supplementing the missing cooling liquid in the system to ensure smooth cooling circulation.
• System Sealing: Converting the cooling system into a permanently closed loop to prevent oxidation of the cooling liquid and corrosion of components by air.
