Genuine VW/Audi Expansion Tank Cap
$84.95
Product availability:
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.
Comes with seal.
