Default idler pulleys

can the pulleys on the tensioners be replaced?

Are all 4 or them the same?

I saw a thread about a redesigned pulley - is there a different part number?
than 12564401 ?

Thanks!

From what I understand, the top idler pulley is different from the original one installed at the factory. If you install them yourself, be careful not to over tighten.

Yes they can be replaced. Get them from Gene Culley if you can or a local Napa will have them too if they are really bad and you need them right now.

Just to make sure I asked the question correctly -

You can change the pulley on belt tensioner without changing the whole assembly?

I don't know if you can get a repl for the pulley itself. When I had my sc, I had belt slip issues so I upgraded to the LS2 tensioner. But for some reason, the pulley would not line up and my belt kept slipping. So I took the pulley off the old tensioner and put it on the newer tensioner. I did this while the tensioner was still on the car. The pulley is attached to the tensioner with like a 15mm bolt. If you just need the pulley, I think I have mine somewhere. You can have it for whatever it cost to ship it if that is all you think you need. Let me know. Hope this helps.

Yes, the pulley itself can be replaced without replacing the entire tensioner assembly. You can check on them on the Advanceautoparts.com or Autozone.com site.

Thanks for all the input

I finally got them all replaced.

The two big pulleys (1 grooved and 1 ungrooved) were around $20

I had to go to the dealer to get the idler pulleys for the AC belt

at $57 bucks a piece. I had actually got the bearings from Napa for $11 each but I destroyed the pulley when I tried to press it out.

So the end result is that all of the pulleys (including the ones on the tensioners) are replaceable.
