One way clutch or pulley?

A mid-size luxury crossover SUV, the Volvo XC90 made its debut in 2002 at the Detroit Motor Show. Recognized for its safety, practicality, and comfort, the XC90 is a popular vehicle around the world. The XC90 proved to be very popular, and very good for Volvo's sales numbers, since its introduction in model year 2003 (North America).

Patrick,

The bracket on my 2008 LR2 is slightly different than the bracket on my 2010 S80

I marked my bracket (before removing it) to make sure it went back to the same location

The pictures are from the LR2 but I did the same process on my 2010 S80 (I might have picture somewhere, the difference is very minor)

Here is what it looks like with the bracket re-installed (Note the alignment marks, Red Sharpie)

Good Luck

Paul

Thanks Paul.
I just wanted to confirm it was possible. I assume you have had no issues with belt misalignment?
I noticed that some people online have referenced a step by step procedure somewhere to complete the belt change. My VIDA is pretty sparse on the details and disjointed in terms of an overall procedure ...any idea if there is a step by step published elsewhere?
Once my water pump and coupler arrive later this week, i’ll dig into this job.

Cheers
Patrick

PS..Glad to see you are also a member of the Volvo /JLR club.( I’m currently mid install of a Webasto auxilliary heater on my 2003 Land Rover)

Patrick,

I do like my Volvo and my JLR.

The belt replacement on the XC90 is slightly different than S80 or LR2

Take a look at this link https://www.freel2.com/forum/topic33363.html

The start of that thread is for doing the work on a LR2 and further down a XC90 3.2 owner shared some tips

Take care

Paul

PS I almost forgot, I don't have any alignment problems

Thanks very much for the tips!
Ill report back when done.
Currently replacing the rear main seal on my 91 780 Coupe....not much fun....XC90 is next on the chopping block once I finally receive some wayward parts in the post.

Argh, what a complicated topic this has become.
Toolpusher,

Now that you replaced the over drive pulley and the belt can you give an update on what you found.

1. Was the One-way clutch pulley seized?

2. Did the rattling / grinding noise that you were hearing go away?

Thanks

Paul

Actually I can’t tell. I was just happy that I was over with the job. The rattling noise is gone.

It is probably worth noticing, that FCP euro sells the one way clutch in a kit for the scheduled pulley job.

So as an encouragement to everyone who wants to try it. Just finished today the same job on our second Volvo. This time it took me proximately four hours. So it is definitely doable. Can just reiterate how useful it is to lift the AC compressor out of the way.
I have one question. The cable and wiring wraps have disintegrated on this car. Is that something I should fix or can I leave it as it is?

I just purchased a high mileage xc90 and trying to figure out if somebody was able to put back the ac bracket without the alignment jig. The jig is around $150 for 1 item use :(

the serpentine belt on mine disintegrated and destroyed the idler and tensioner pulleys, I made a stupid mistake of taking out the ac bracket without making alignment marks (I didn't realized that an alignment jig is needed)

if somebody can loan it for me, i'll pay shipping and I'm in Kansas City.

I did the job on two cars.
On the first one I forgot to put marks, but when putting it together there was no play that I noticed in the bracket that would allow any alignment.

Now for the second job, I marked each and every screw and joint, but it turned out when I put everything together, as soon as torquing up, the bracket just slips in that one original position and all the marks line up perfectly without any alignment.

So I’m really wondering what this alignment tool is needed for.
