17214674 Volvo Excavator EC210B EC240 EC290B Coolant Expansion Water Tank 11110726

The coolant water tank, also known as the expansion tank or coolant reservoir, is an essential component in the cooling system of an engine, including those found in heavy machinery like excavators. Its primary function is to store coolant, which is crucial for regulating the engine’s temperature and preventing overheating.

The coolant water tank serves several important functions:

Coolant Storage: The tank holds excess coolant that is not currently circulating through the engine. This is particularly important during engine operation, as the coolant expands when heated. The tank provides a space for this expanded coolant, preventing pressure buildup in the cooling system.

Pressure Regulation: The coolant water tank helps maintain the proper pressure within the cooling system. 

Coolant Checks: Regularly checking the coolant level and condition is important. The coolant should be replaced according to the manufacturer’s recommendations to ensure optimal performance and prevent corrosion.The cooling radiator of the EC290B excavator is a vital component that ensures the engine and hydraulic systems operate within safe temperature ranges. Understanding its function and maintaining it properly can help enhance the performance and longevity of the excavator, ultimately contributing to the success of construction projects.

The primary function of the cooling radiator in the EC290B excavator is to dissipate heat generated by the engine and hydraulic systems during operation. As the engine runs, it produces heat as a byproduct of combustion, and the hydraulic systems also generate heat due to fluid movement and pressure. If this heat is not effectively managed, it can lead to overheating, reduced performance, and potential engine damage.
