My idler pulley has started to chirp and squeal. I noticed it while driving with the windows down the other day and was able to confirm the idler pulley as the culprit. With almost 125k on the clock, it's not a big surprise.
I'm going to replace the idler pulley (which needs to be serviced), as well as the tensioner and accessory belt (as preventative maintenance).
I've done this job once before on a Jeep Wrangler and it was pretty cut and dry. I did a search and couldn't find any threads on here discussing the idler or tensioner.
SQOD - Any tips for replacing either/both pulleys and belt on the 5.7L? I'm assuming the process would be very similar, if not exactly the same, as the Tundra of similar vintage - which has a few videos of varying quality on YouTube.
@Mogwai any input on this from your recent repair? I know these parts were replaced as part of your WP install, but how long would you estimate the replacement of the idler and tensioner pulleys to take? Do you have the torque specs for bolts?
