        The "radiator cap" is a component of a vehicle's cooling system. Its primary functions include: Pressure Regulation: The radiator cap helps regulate the pressure within the vehicle's cooling system. It is designed to maintain a specific pressure level, allowing the coolant to reach a higher temperature before boiling. This higher boiling point helps prevent the engine from overheating. Coolant Recirculation: When the engine is running and the coolant heats up, excess pressure builds up in the cooling system. The radiator cap allows the release of this excess pressure, and when the engine cools down, it also enables the coolant to be drawn back into the radiator from the overflow or coolant reservoir. Sealing: The radiator cap seals the top of the radiator to prevent coolant leakage. It ensures that the cooling system remains pressurized, which is crucial for maintaining an efficient and consistent operating temperature. In summary, the radiator cap plays a crucial role in regulating the pressure, facilitating coolant recirculation, and maintaining the integrity of the cooling system in a vehicle.
