Default power steering belt slip with new belt

On cold startup, Im experiencing some belt slip. The first thing I did was replace the dried and cracking belt. Unfortunately this didnt stop the problem. I still get the tell tale squeel, and the steering wheel is difficult to turn until the belt catches. I have tightened the belt up twice, and I am afraid to tighten it further. Any idea what could be causing the issue? I have also tried belt dressing, but it only covers up the noise for a week or so. I havnt manually tried spinning teh alternator or p/s pump to see if the bearings are seizing up, but I don't hear any grinding. Any ideas? Its an 06 WRX with 100K on the clock. Driven like a grandmother - still on the stock clutch.

I had the same squeak problem. Thought I was tightening it up enough then read the manual. Manual says From the alternator to the crank the play in the belt (deflection) should be between 7-9mm or .276 to .354in. Thats pretty tight. Sneak a tape measure down there perpendicular to the belt then push on the belt and see how far it moves. Mine was squealing like a pig with 1/2in. After tightening it down less than a 1/3rd it was quite. Short answer keep tightening and make sure you loosen the clamping bolt. If you striped the thread right were you need to make it a little tighter you'll never get it tight enough.

You're talking belt deflection with your finger, right? Im sure its at least within this range, if not tighter already. Its takes quite a bit of pressure to get the belt to deflect 1/4 inch.

Right, push hard with a finger or two. Is the belt in the right grooves. I had it once where my ac belt was one groove off. Just a thought. I say go tighter otherwise, just to see if it helps. Any other scoobys around you can compare to?

I have a 2012 outback in the driveway, but not the same motor. The belt is much tighter than most GM cars with tensioners, for what its worth. I know the belt is seated correctly. When I replaced the belts, I ran the car around town for a few miles, then rechecked that the belts were seated correctly and had tension.

Ha ha! As a matter of fact it is a gates belt. I bought it along with the gates timing belt kit that's sitting in my bedroom waiting to go in.

Perhaps its residual chalky belt dust from the dried and cracked belt that was fraying before I replaced it. Or perhaps its slipping due to the belt dressing now. Maybe Ill get to the bottom of it when I finally crack her open to put the new timing belt in.

Take some white out and draw a line across the pump shaft and the pulley. It's possible your pulley is slipping on the shaft of the pump. The white out will tell you pretty quick if it is, just make sure you let it dry before starting it.
