Expansion Tank Cap

Description

The coolant expansion tank cap maintains an elevated cooling system pressure to raise the boiling point of the liquid coolant, while venting excessive pressure to atmosphere. These caps have a limited service life; they should be pressure-tested as part of a routine maintenance schedule, and replaced as part of any major cooling system overhaul.
