504136607 for IVECO Daily IV 2006 ENGINE Diesel Cooling System Coolant Water Expansion Tank M

Car expansion tank is installed in the engine compartment of a vehicle for storing additional coolant (also known as antifreeze or cooling agent). It is often a small plastic or metal container that is connected to the vehicle’s cooling system to provide additional coolant reserve.
Functions of a car expansion tank:
1. Replenish coolant: In the case of insufficient coolant in a vehicle’s cooling system, additional coolant can be added by the expansion tank, thus ensuring normal operation of the cooling system.
2. Maintain pressure balance in the cooling system: The expansion tank is typically connected to the cooling system, and a pressure valve is used to maintain pressure balance in the cooling system. This helps prevent coolant leakage or excessive pressure.
