Just replaced a power steering unit and am getting what it sounds like the belt rubbing on the side of the pulley. Is the belt to loose? How do I bleed the air from the lines? The vehicle is a 1987 chevy suburban 5.7 engine. Originally the power steering unit had a pulley that had two grooves when I ordered the part the guy ended up getting a single groove pulley. I am curious if I could still run my ac with a single pulley? Here is how I attempted to bleed the air from the lines after installation. I left the cap off of the container that holds the power steering fluid and slowly turned my wheels to the left and then to the right. I did not have the vehicle jacked up. Is this the proper procedure to bleed the air?

I don't know if this will work, but I'm going to try and attach a copy of general instructions that came with my hoses.

If you have no specs, tighten until there is about 3/4" deflection when pressed in the middle of the longest run with your thumb, using moderate pressure.

As long as the pulleys all line up, but if all your accessories are being run off the one belt, it may have a shorter than usual life and may need tightened more often.

Yes, the cap doesn't need to be left off, though. Don't peg the wheel left or right very hard, and not for very long, either. Refill as needed.
