The radiator cap not only seals the radiator, it also maintains the pressure inside the radiator at a certain range (typically around 16 PSI). Depending on the radiator cap type, the radiator cap is also responsible for allowing excess coolant or gas to escape.
Most radiator caps typically cost around $10 to $30. Several factors affect pricing, such as the brand, radiator cap type, and its PSI rating.
