I'm about to swap out my tensioner pulley(s) due to a persistent under-hood squeal. Any "gotchas" in doing this?

Do both the idler pulleys, belt and a complete tensioner, not just the pulley.

Thanks, Mike. I did the belt about 2.5k ago. I replaced the tensioner today (the whole assembly) and that seemed to address the squeal. Regarding the idlers, the originals are metal, but at AtlanticBritish, the replacements are poly. What are your thoughts here? Should I still replace them? If so, can I go with the polys from AB, or should I track down some metal ones? If so, from where?

Thanks, and I hope y'all had a GREAT holiday!!![/blockquote][/blockquote][/blockquote][/blockquote]

 

The poly's will be just fine.
You might beable to swap the polys for the metal ones.
