Coolant Cap - Preventive Maintenance
(Aiken, SC) | January 14th, 2021
On any 10+ year old Boxster/Cayman, replacement of the coolant cap in the trunk should be mandatory preventative maintenance. With time, the gasket on the cap compresses and no longer seals perfectly. Signs of even minimal leakage from the cap are a whitish residue on the threads on which the cap seats. My 2011 Spyder showed such signs. You can replace just the gasket, or for a very reasonable price just get a brand new Porsche parts cap from Suncoast, which is what I did. Great service!
