Shopping for Radiator Cap

Radiator Cap Shopping Info

What Is a Radiator Cap?

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.

How Much Does a Replacement Radiator Cap Cost?

Most radiator caps typically cost around $10 to $30. Several factors affect pricing, such as the brand, radiator cap type, and its PSI rating.
