Visited dealer yesterday for oil change and filter... a "recommendation" report based on current mileage of 103,000 miles (2010 S80 T6) to replace "auxiliary drive serpentine belts and tensioners." Service manager advised this was recommended by Volve at 10 years or 110,000 miles. Cost was $1460 miles.
Evil things will of course happen if that belt breaks. Does the timing and price seem reasonable? Will be checking with two indie shops for estimates but of course curious about any member experiences. Did a search for "serpentine belt replacement" on this forum and got nothing back.
