Power Steering Pulley Out of Alignment? [message #307708]

I've been away from the GMC for awhile but started it up today to take a quick ride around the block and make sure all systems were go. Heard a different kind of noise from the engine bay, so popped open the cover. Was reminded while looking at the front accessories that I was unable to get my power steering pulley back into full alignment after I changed the water pump (along with the aluminum radiator). I took a 20-sec video of it running and shutdown, would greatly appreciate anyone's thoughts.

The problem I remember having was the tightening of the belt for both the power steering and alternator would cause the bracket holding the power steering reservoir to start to tip in. The attachment bolts for the bracket were inboard of the pulley, nothing on the outside to keep it in place. I snapped a pic of the outer side of the bracket in hopes that could shed light.

Any guidance? I can see the alternator belt is twisted a little as it heads from the power steering pulley up to the alternator and I'm fairly certain that couldn't be good for long term survival.

I can't explain why my picture is upside down and HUGE. It looks fine on the photo site.

I certainly hope nobody was injured standing on their head while investigating!

Check the stud on front of engine. The power steering should be against the stud first with the top left radiator shroud bracket on the outside.

Page 9-15 has a diagram of all the bolts and brackets. I'd expect one of
the inner side bolts that connect the pump to the bracket.

Oh, and your video is marked private.

There is a strut that goes from the ex manifold bolt over to ps pump mount. I can't see if it is on yours.

You nailed it again Wally. That bracket is missing on my engine, and based off the condition of the exhaust manifold bolt, it has been missing for awhile.

Anyone have a spare?

Also look closely at the parts breakdown and note that there should be a washer between the bracket and the pump on the bolt used to clamp the pump.
That will keep the pump reservoir from contacting the bracket and should help to straighten the pump. Tough to get that washer in, but as I found out, it is needed.
