So, HI!!

Okay, my 2001 9-5 Aero has made a high pitched noise since I bought it when the A/C is off. The previous owner says that he went through some deep water once and that the A/C clutch/bearing is dry. That makes sense. Anyways, is there a way to grease the bearings without removing the whole thing?

Another A/C question: This noise was usually not a big deal because I would just not leave it on ECON mode and it would be quiet. Now that it is cold, I noticed that the compressor does not kick on when the temp goes below 32 degrees. Is this a programmed feature? Like it wont kick on below 32 degrees for safety?

Also, what is more prone to make noise at 100k+ the water pump or the power steering? I just replaced my upper idler and ran a short belt and there is still a loud accessory noise coming from the front accessories (besides the A/C being off noise).

Thanks!

I wouldn't have gone for the short belt switch since it apparently makes more engine vibration, but you did it already so whatever. I think that the water pump is usually the first to go, the power steering should be fine. Btw I put a gatorback belt on when I changed mine and the thing doesn't slip at all.

I don't think it is engine vibration that it increases, its just a bit of chatter from the extra room for slack. However, I have seen absolutely no difference. And Breau, the reason why I changed to a short belt is because my middle idler is bad and I am not about to change that fucker. Mine doesn't slip either, no problems reported.

Those a/c compressors do hate to get submerged. I do a lot of flood cars and almost all of them need a compressor. It is tough to pinpoint the noise from them. As for the short belt, I've really only noticed any belt "flutter" if you're doing tight manuvers steering

what you could do is do a short belt and a/c skip size belt I resantly put one on mine. I dont have the belt number that I used handy, but the belt size is 1816mm or 71.4 inches.
I'm currently in depth with a water pump work at 96k miles


EDIT: Dayco Belt
