The person at the local auto parts store will be able to answer that question and show you it in the book. Go visit them.

Index of /ilh/vacation You should be able to find the info in the service manual, or most Dealerships website will have a link to parts.

The original poster is from Chile, and may not have access to such resources there to sort out these part issues - the Outback is pretty rare there.

@marcelo_pe - have a look through this thread; it discusses in quite a bit of depth exactly the issue you are facing. Good luck!

 

Thanks for the answers! You guys are awesome!

Newer models are becoming popular now. It's great to see those beauties on the road. But older models like mine are rare.

On top of that, auto parts stores are just crazy expensive here, taking advantage of our poor car culture. I'm sure they won't clarify my doubt if that means selling me the whole tensioner, which is obviously more expensive.

I feel confident now and will buy both pulleys on Amazon for half the price the local auto parts store charges for just one. You can now imagine how precious this info is (thanks @avk !)

 

The two pulleys are identical on a 3.0 l engine, different on a 3.6.
