Changing serpentine Belts 2000 Grand Prix GTP

It is very easy. You will need one socket on a breaker-bar to grab the bolt that mounts the pulley to the idler just so you can rotate & unload the tensioner. 15mm if I remember right. The belts slip off & you simply wind a fresh one on the same way. There is also a picture of the routing in case you loose your way.

Check all the idlers (& there are a pile of them) for slop while you are at it.

Thank you.
