Крышка радиатора двигателя Caterpillar 6029381

An Engine Radiator Cap is used to maintain the correct pressure in the cooling system. It prevents coolant from escaping at high temperatures while allowing excess pressure to vent safely into the overflow tank. It also ensures coolant returns to the radiator as the engine cools, maintaining optimal fluid levels. This stabilizes engine operating temperature, preventing overheating and avoiding coolant loss.Attributes:• Releases excess pressure to an overflow reservoir when required.• Ensures coolant remains at the correct level within the radiator.• Provides consistent sealing during repeated heating and cooling cycles.Applications: An Engine Radiator Cap is mounted on the radiator neck, controlling pressure, preventing coolant leaks, and ensuring correct fluid circulation between the radiator and overflow reservoir.
