1997 GMC Yukon Belt Noise

Question: I just had the power steering pump replaced on my 97 Yukon. The power steering works fine now, but the belt often squeals. My husband sprayed some of that belt quiet spray on the fan belt, and it stopped squealing for a few minutes. Then the racket came right back. What could be making the noise?

Answer: Of course, if you haven’t changed the belt and or the belt tensioner, you should do that. BUT, the pulley on those power steering pumps are just press fitted on (they have no bolts holding them on.) And I’ve seen a lot of them not pressed back on far enough when the pump is replaced (you don’t get a new pulley with the new pump, you reuse the old one.) Have the pulley checked to see if it isn’t flush with all the other pulleys in the system. If so, just have it pressed further back on. This can be done on the truck with a special tool that most mechanics have.
