An Expansion Tank is responsible for maintaining the proper level of coolant and regulating pressure fluctuations. As the engine heats up during operation, the coolant expands, necessitating a reservoir for accommodating this expansion and preventing overpressure in the cooling system. Conversely, during cool-down periods, the tank allows for contraction of the coolant volume.Attributes:• Resistant to degradation of coolant.• Maintains proper coolant level.• Accommodates thermal expansion and contraction.Applications: An Expansion Tank ensures that the cooling system functions correctly, the Expansion Tank contributes to the overall reliability and longevity of the engine.
