Крышка радиатора, наружный диаметр 70 мм Caterpillar 293-9250

A Radiator Cap serves as a seal for the radiator hose connection and helps regulate the coolant pressure within the cooling system. As the coolant heats up, it expands, resulting in an increase in pressure within the cooling system. The radiator hose cap maintains the system pressure at a safe level by allowing excess pressure to escape through the pressure valve. When the coolant cools down, the cap also prevents air from entering the system, thus maintaining the system's optimal pressure.Attributes: • Ensures efficient operation and reduces the potential for environmental hazards• Withstands extreme pressure and temperature conditionsApplications:A Radiator Cap ensures that coolant does not leak from the connection point between the radiator hose and the radiator neck or coolant reservoir inlet and prevents coolant loss, which can lead to inadequate cooling and engine overheating.
