It seals the radiator filler neck and pressurizes the system, raising the coolant boiling point to prevent overheating under load. The cap also includes a vacuum relief valve that allows coolant to flow back from the reservoir as the engine cools down. You typically replace it when the cap no longer holds the correct pressure, which can lead to coolant loss, boiling, or overheating.
