It seals the coolant surge tank and maintains system pressure at 15 PSI to raise the coolant’s boiling point and prevent fluid loss. A worn or leaking cap can cause overheating, coolant loss, and possible engine damage. Replace it if you notice coolant seeping from the cap, frequent low coolant warnings, or pressure loss during operation.
