Expansion Tank 17117573751

Replace : 17137514401

The Expansion Tank, also known as a coolant reservoir, plays a crucial role in the vehicle’s cooling system. It serves as a storage unit for excess coolant and facilitates the expansion and contraction of the coolant as the engine heats up and cools down.

Working:

During engine operation, coolant circulates through the engine, absorbing heat. As the coolant heats up, it expands. The excess coolant flows into the expansion tank, relieving pressure in the cooling system. When the engine cools down, the contracted coolant is drawn back into the system from the expansiontank to maintain the proper fluid level.

Compatibility:

The AutoStar ExpansionTank with part number 17117573751 is designed to be compatible with specific BMW vehicle models. It functions similarly to the original equipment part, serving as a container for excess coolant and assisting in maintaining the proper coolant level in the cooling system.

Purpose:

This expansion tank aids in regulating the coolant system’s pressure and allows for the thermal expansion and contraction of the coolant, ensuring efficient cooling and preventing potential damage from excessive pressure build-up.

In summary

The AutoStar Expansion Tank with part number 17117573751 is an essential component of the cooling system in certain BMW vehicles. Its purpose is to store excess coolant, regulate system pressure, and facilitate proper cooling by allowing for the expansion and contraction of coolant within the system.
