==Overview==
The serpentine belt, idler and tensioner pulleys should be inspected every service interval and in theory, replaced every 60k miles, but a pulley bearing often fails earlier. Cost of replacing two pulleys and the belt can be $200-300 for parts and labor plus towing. Alternatives include replacement as preventive maintenance (about $100 for a new belt and two pulleys), the short belt conversion ($60-70 for one pulley and the belt), and aluminum pulleys with replacable bearings. Repacking the pulley bearings is also possibleto extend their life.

===Bearing Repacking===
Repack bearings by prying off the cover with a small pick or nail. Apply synthetic grease and rotate the bearing until the grease works itself through the race. Reapply the cover and then use silicone sealant to keep the grease from exiting when the pulley spins.
