I want to replace the pulley on my belt tensioner (squeaks) but I don't want to replace the entire tensioner just the pulley because I don't want to remove the A/C to get to the bolts. The pulley however comes off super easy just like the two idler pulleys do. So I really just want to replace the pulley but only see them sold as idler pulleys not tensioner pulleys.

If the bearing is squeaking then this may work but the are not sold separate because the tensioner is a loaded pulley to put the tension on the belt and they don't want people "messing" with that.

If you are just looking for a part source on the pulley, then I am not sure we have a source for this either. I checked a number of different sites, even ebay for just the pulley and I don't find anyone selling just the pulley.

I would suggest either buying the entire part and remove it from the new one or going to a salvage yard. They may have it or at least cheaper and then you can remove the pulley from that one.

Let me know if you have other questions on this. Thanks

Yes, thank you very much for the prompt reply, I have since posting have learned they do not sell just the roller and for the reasons you stated. Now getting the A/C unit out of the way to get all the tensioner bolts off has proven to be utterly impossible I have the A/C unbolted but due to the fan shroud and coolant overflow it only moves a couple of inches and I just can't get the last belt tensioner bolt out, but I will keep trying!

Unfortunately, it is not easy when that stuff is in the way. Are you using swivel sockets so that you can get to it from different angles? I think they are the best invention for mechanics.

Get a picture of what you are dealing with and we can probably give you some ideas on how to access it.

Actually just saw this now. So, no I don't have any pictures but finally got the belt tensioner replaced and the abrasions on my hands should heal in a couple of months. Glad it's done!

Haha. That is very good news (about the car, not your hands). O'keeff's working hands is the best thing I have found. Thanks for the update. Glad it is taken care of.
