WG99255300031 Cooling System Expansion Tank for CNHTC Sinotruk Howo A7 Truck

Expansion Tank is used to store and release coolant in the cooling system. Its functions include:
1. Supplementing coolant in the cooling system: When the engine is running, the coolant in the cooling system is circulated, and the expansion tank can provide additional coolant to ensure that there is always enough liquid in the system to cool the engine.

2. Allowing for the expansion of coolant: As the engine runs, the coolant will heat up and expand. The expansion tank provides a container to accommodate this expanded liquid, preventing the cooling system from overheating or building up excessive pressure.

3.Prevention of Bubble Formation:During coolant circulation, the expansion tank helps expel air bubbles, maintaining the fluidity and efficiency of the coolant.

In summary, the expansion tank plays a crucial role in maintaining the proper operation of the cooling system and protecting the engine from overheating.
