I've seen 2 reports the serpentine belt tensioner and idler pulleys for the H6 (at least 2001-2003) is bearing# " 6203-2rsj ", seems like this would make a good sticky, especially as they seem prone to failure.

Thx to 50075 and procyon650

i've seen 6 reported failures this week alone on various sites.

My '03 is a bit over 90,000miles, I think I'm going to do mine before too long.

Man, its tight behind the radiator, though.

When this happened on my 05 outback H6 the mechanic was able to get both pulleys out without removing anything. He was also able to use a press to change the bearings instead of replacing the entire assembly, saved me some $. The replacement bearings were only about 6$ each.
That's about the price for the part# I listed- its just the bearing that goes inside the pulley for the idler, and the tensioner.

yesterday replaced both tensioner and idler pulley they were 50.52 before tax each from the stealership, gonna buy two bearings and press them in into the old ones to have spares.
Weird- usually the idler is cheaper and the tensioner more expensive.

If you got both for about 100 that's less than the $125 I've seen just the tensioner one goes for.

I'm curious, what are the symptoms that the bearings are going out?
Judging from the way it just pukes the belt, I'd have to say they give very little warning.

A bearing about to fail might make a grinding or whining or rumbling noise, and you might be able to see the pulley cocking to one side if it's really bad.


You probably need to use a mechanics stethoscope (or long metal rod/screwdriver/etc held against your thumb, your thumb aganst your ear) placed against the pulley bolt with the engine running to really tell, not for the faint of heart, and you probably would need to hear it with good bearings (to know what 'good' sounds like) 1st to tell if they were going bad.

I noticed that the range listed was 01-03 and mine is an 04. I was wondering if they addressed it in 04?

then again there's another person who has an 05 and he had them changed as well.
I don't know if it takes the same bearing for '04.

I'd say listen to them with the improvised stethescope (if you're up to sticking a piece of metal right next to the turning belt...) and use that as a baseline.

Gets any noisier, replace 'em.

where did you get the bearings? The dealer is ordering me a tensioner today for $100. he told me the bearing wasn't available individually.
Just google the "6203-2rsj", also "6203" seems to be a number NAPA uses.

There have been some reports it is a fairly easy fit, and (mostly) others saying a press was required.

A long bolt/ piece of all-thread, some nuts, a good supply of washers, and some ingenuity can often do the job when it comes to bearings, but I haven't done mine yet, so I don't know what it will take.

I'm at 120,000 miles now (30K miles in a year), gee, I feel like I should do them.

Like maybe this weekend.

Might have heard a bit of noise...

Maybe I'll try taping the belt to the other pulleys so I don't have to fuss with getting them back on.

Yeah I'd do it dave. With the frequency they happen (someone at USMB just had it let loose on them) and how bad mine were when I did them for preventative maintenance it's time well spent. It was REALLY easy too by the way. Given your experience I think you'll knock it out in no time. Actually other than a couple pilot bearings I dont' think I had ever done a bearing before so I was a little hesitant but it ended up being a piece of cake. Bearing came out really easy.
Nothing standing between me and new bearings but a big pile of lazy...

I was going to change my trans fluid this weekend, but this seems like a 'need'.

The non-tensioner idler on my wife's '06 Outback 3.0L had just started making noise. 59k miles on the car. Pulled it off and took out the dust seals. The small amount of grease still in it was all dried up. Cleaned it w/ brake cleaner and repacked with grease and is spun pretty smoothly.

I've now replaced one idler with new ($43) so that I had a spare to press in a 6203-2RSJ bearing from NAPA which was only $10. I used a few washers and a hydraulic press at work. BTW, the bearing from NAPA is made by SKF.

I almost think replacing both idler bearings should be on the 60k maintenance schedule.
60K for the stockers, anyway.

Surprised to hear they are still shortlived in the '06.

I pulled it off this morning and there's no play in the pulley bearing, perfectly smooth? I removed the tensioner too but nothing noticeable.

I'm %100 sure something was wrong, every few seconds it would vibrate horribly, I could even see the bolt moving.

So it must be the tensioner?
The tensioner arm should be able to rotate, but not deflect around its pivot by much.

It is normal to have the belt run smooth and then flap a bit and then smooth out again.

The letters relate to seals, perhaps a speed rating and load rating.

I don't think it's a high-load high-speed job on the subie.

Maybe I missed it, but are steps for simply checking the bearings?

I assume I can just lessen the tension on the belt and check the bearing for any noises or play.

I only have 81k miles but it is ten years old, so I'd like to check it.

Thanks
Yes, you can. With the belt fully off the pulley (not just loose) spin the pulley, it should spin quietly, and should of course have no play.

Getting the belt on/off is a fair bit of the job, mine and a co-workers went before 80k.

I would say the H6s have head gasket problems about as often as any vehicle that has no real tendency for leaky head gaskets.

No matter how well designed and assembled, there will always be some small rate of failure.

My H6 has a very slight external weep that the subie magic elixir may have slowed down a bit.
