Serpentine belt and pulley's
2002 C4S owned for 14 months, came with all records from 2005 w/23k miles. Has had IMS update. The upper serpentine belt pulley failed. No pulley's or tensioner replacement shown in records. I'm considering replacing the 2 idler and tension pulley, and the tensioner. Does the tensioner get weak over time? Is there a higher failier rate one over another? Is it necessary to do all? Are they all relatively easy to do? Any special tools? Did I ask too many damn questions? (o:
