Hi! I'm about to change the serpentine on my '05 3.6L with 56k miles as soon as I get a 24mm nut or wrench.

I'll check smoothness of the water pump and other accessories when the belt is out. However, I'm not sure if I'll need to replace my tension and idler pulleys. If I do, can anyone help me by providing the part numbers for them? Any tips or gotchas when replacing them?

Here's what they look like (the tension pulley's surface looks similar to the idler pulleys):

Thanks!

 

If there is an actual lip in the pulley, I would change it. Otherwise, I'd leave them as long as they aren't making bearing noises or anything. We do offer a full selection of tension and idler pulleys, for more information Click Here.
