The Radiator Coolant Tank provides a reservoir for coolant expansion and contraction as the engine heats up and cools down. As the engine warms up, the coolant expands and is directed into the coolant tank, which prevents over-pressurization of the cooling unit. Conversely, as the engine cools down, the coolant contracts and the tank supplies coolant back to the radiator to maintain the proper level.Attributes:• Withstands a wide range of temperatures, from extreme heat generated by the engine to cold ambient temperatures• Resist the pressures generated within the cooling unitApplications:The Radiator Coolant Tank serves as a reservoir for the coolant's expansion and contraction during engine heating and cooling.
