Default I need a diagram or good pics of the accessories belt tensioner...

OK, had my 100k service done ~5k ago.
Noticed a bit of a weird dentist drill type noise coming from what I thought was the alternator.
Took it back, they readjusted the tensioner and it would either slip and go away (but screech) or make that noise. They said it was normal...

Fast forward to Monday and my wife was driving the WRX. She can drive stick, but isn't the best with the WRX. She did something where she started hard in first and said the car smelled funny after that (so burned the clutch a bit, no big deal). She also said there was a funny noise when she started it again... So when I got home last night we had to drive to a Bday party and the WRX works way better with the 2 of us and the baby...

Well I hear the noise and immediately hop out and open the hood. The tensioner that looks like a vertical bolt that starts under the plastic cover? Yeah, the bottom part of that is just hanging there between the belts... The lower pulley also seems really loose. But the bottom is bouncing around loose in there. Does anyone have a diagram or pics of how this goes together? I had zero time to look at it, we just hopped in the other car. I plan on taking it right to a local dealer, but I'd like to see if I can get it together enough to drive it there instead of calling a flat bed (I do have AAA so I'll have to look into how far the dealer really is and what my coverage is...).

So please, if you can help me piece it together I'd really appreciate it.

Thanks!

Ben

The tensioner for the alternator has a bolt on the pulley itself. That seems to be loose, if i am reading correctly. Its a 12mm bolt, you have to loosen that, then loosen the vertical bolt to relive the tension. So if you tighten the vertical bolt up enough, then tighten the bolt through the pulley should be okay.


sorry if I misread your problem :-/

yeah, the long vertical bolt... the bottom is just dangling there between the 2 belts... It's not attached to anything!

I didn't have any time to really look into it, maybe it's obvious, but I'm looking for pictures or diagrams of how it goes together so I can put mine back together.

The bracket is plastic, it's probably broken. You can get the assembly from a dealer and replace it yourself.

so like the bottom part it attaches to?

Also I'm thinking if I go to the dealer to pick one up/order it they'll have their parts diagram that might help me figure out if I'm on the right track...

OK, I'm pretty sure this is the part I need:


anyone know what that is? Will taking that picture in (not of my motor) and telling the dealer I have an 04 be good enough that they can help me get the right part? At this point I just need to get the part so I can take it home and put it in...

Yep that's the adjuster piece that moves up and down, it's plastic and usually breaks when someone tries to adjust the belt without first loosening the lock bolt on the pulley. I think it's only available as an assembly with the adjuster and pulley, in any case I'd suggest replacing the whole thing.

Cool, thanks.

And this is just the AC belt on a 04 right? So it's nothing that could cause serious problems? Also, would installing all 3 parts be straight forward enough for me to do it in my driveway? Also, one last thing, know the part #s by chance?

Thanks for the help. I really appreciate it.

73134AC001 is the PN for the adjuster. if you want a whole new assembly, i can dig those numbers out for you aswell. Its a extremely simple install.

I ended up needed the pully as well as it had gotten a flat side when this happened. I also replaced the belt just in case as I didn't want to have more issues once I had it all apart and back together again. Wasn't too hard at all IMHO, and the weird noise my alternator was making is fixed now (I think they tightened that belt too much when they did the service).

old and new:


I had left the pulley on the belt when I replaced the part, as I was putting it all back together, something didn't feel right so I took it apart to find this:


so I took everything out so the car was drivable (w/o AC obviously):




didn't take any pics with it back together, but go look under your hood and you can see that easy enough.

Old thread I know, but I have the same issue. My adjuster is broken as well.

Car is a 2001 RS

Can somebody give me a step by step to remove the belt/pulley?

I ordered the adjuster, but now I'm worried that the pulley may have a flat spot, in which case I'll cancel the order (hasn't shipped yet) and just run to a dealer and get the whole assembly. Any way to check for a flat spot without removing the belt?

What tools do I need to do this? I just moved to a new city and don't have any tools readily available, and want to buy only what I need from the hardware store.
