A vehicles cooling & heating system is a vital component for the engines efficiency. The radiator cap is used to contain and build pressure of the cooling system at extreme heats. If the pressure is not sufficient, it may lead to overheating so to keep it balanced the radiator cap valve opens so that coolant can escape the radiator. If your engine is overheating or steaming is released by the radiator, then a new radiator cap maybe required.
