Крышка бачка радиатора Caterpillar 6608903

The Radiator Tank Pressure Cap regulates the pressure inside the cooling system by sealing the radiator and controlling fluid return. It maintains a specific pressure threshold that allows the coolant to absorb and transfer heat effectively without boiling. The cap releases excess coolant into the overflow path, preventing damage from overpressure. It also restores coolant to the radiator as the system cools, ensuring consistent fluid levels.Attributes:• Enables controlled expansion and contraction of coolant.• Prevents loss of cooling efficiency from pressure imbalance.• Ensures pressure stability during different temperatures.Applications: The Radiator Tank Pressure Cap is fitted on the radiator tank to seal the cooling system, control pressure buildup, and manage coolant transfer between the radiator and overflow reservoir.
