Default 2005 Outback 3.0 Belt/Pulley Problem

Hi all,

My wife's Outback had a squeal coming from the passenger side under the hood that I noticed a day or so ago. On the way home this evening her Battery Light and Brake Light came on and the power steering went out. I figured that the Serpentine Belt just broke, since the car has about 170k on it.

Anyway when we get the car home, I popped the hood and noticed that the belt was in one piece but wasn't on the pulleys. After looking a bit closer I noticed a "pulley" looking thing at the bottom of the engine compartment. I see where it belongs and a pulley just like it still in good shape (turns fine, no squeals) and still attached on the Drivers Side near where this one went, but I'm not sure what it is, where to buy one and how it goes back on. Any help would be greatly appreciated.

Sorry for the grainy pictures they are from my cell phone.

Thanks,
Dave

Update: Just called the dealership, they said the part that is broken is the Accessory Belt Tensioner. They have one in stock, so I'll get it after work. Any ideas on how this mounts and what I have to take off to get it installed?

Thanks,
Dave

31 views, a several page thread in the 3.0 forum and no one has replaced this part? Hmm, maybe I'll take pictures when I do it.

I installed one a few months ago. It's a simple 2 bolts installation. The only thing you need is either a deep socket or regular socket with a short extension. One of the two bolts hide pretty good below the alternator. It takes a little patience to install the bolt. Otherwise, it's a simple bolt on. Also, make sure the belt route properly. I would install a new belt as well for just in case.

Yeah, take pictures and post them up.

Like others, I looked at the thread but ... I don't have a h-6 motor or a repair manual for one so couldn't help much. I assumed it was either a static idler pulley or a tensioner but didn't know which. I'm surprised the tensioner arm and pulley bolt both came out ... left the pulley in the pan but not the tensioner or the bolts.

I assume you dropped the underdoor down and looked for the other parts.

Well,

It's done. I did both the tensioner (the pulley on the passenger side) and the idler pulley (the pulley on the drivers side. As vwtopdog said it was pretty simple. The bolts are well hidden and it took a good bit of patience, not to mention some cussing, but I had it done in about an hour total for both and putting the belt back on. Probably the hardest part was the routing of the belt. I don't have a service manual so I had to find a belt routing diagram online. Once I had that, I was all set. She's back up and running fine. I didn't get a chance to take pictures though, it was getting late and dark in the garage.

Thanks,
Dave

I told you it was simple.

I hope you didn't throw away the old pulley. I popped the worn bearing out from the old pulley and pressed in with the new bearing. New bearing only cost about $7. Now it's ready to be use again.

You can pop the worn bearing out by placing a socket small enough that fit into the opening from the back of the pulley. Then place a small piece of hardwood in front of the pulley to protect the pulley surface. Put the whole set up in a vise. It will take a little muscle to squeeze the socket through and push the bearing out. Once it's out, just reverse the set up to press the new bearing back in. Cheap and easy.

I heard the bearing on those pulley typically last about 100,000 miles before it failed.
