Expansion tank 22821828 for

Functional features
Accommodate expansion liquid: When the coolant expands due to heat, it accommodates excess coolant to prevent the cooling pipeline from being damaged due to excessive pressure and avoid coolant loss.
Pressure stabilization and unloading buffer: When the pressure of the cooling system changes slightly, it can play a role in pressure stabilization, unloading and buffering, maintain the stability of the system pressure, avoid water pump cavitation, and ensure the normal operation of the water pump.
Supplementary exhaust function: It can discharge the gas in the cooling system and replenish antifreeze for the system.
