95 bonneville compressor/ bypass pulley breaking

I have a 95 Pontiac bonneville and I’m having problems getting a bypass pulley on my car. Everything started when I was on my way to work and I noticed the power steering was failing so I checked under the hood and my belt had came undone so I set the belt and it popped off again when the car started I took a closer look and noticed that one of the bolts holding the compressor in place had snapped so I managed to get it out and replace the bolt. I began to drive the car and everything was fine and parked and went into a store came out and started up the car and steering went out again so I checked and this time the whole bracket on the as compressor snapped. I tried replacing it with a bypass pulley but they keep snapping like the compressor did I asked around and one persons telling me that a bypass won’t work I need the compressor and another is telling me that the bypass should work and their has to be another pump or pulley that’s bad soo it’s just one big headache and I would really appreciate some help thanks.

Well, this is simple to figure out:

Since the belt is off, turn each pulley by hand, starting with the supercharger pulley.
They should all turn, some freely, others with a little bit of force.
None should wobble.

Any that feel odd, or wobble, replace.


I just checked and everything seems right. I got the pulley from kragen i had modify it a little bit so it would align right you think might have somethin to do with the bracket of the bypass pulley snapping in half
