I have a 1989 GMC Safari with 4.3L engine. My serpentine belt runs from my tensioner to my alternator, down to power steering pump, up to water pump, down to crankshaft, up to A/C compressor. Van was making noise. I noticed that the tensioner is at maximum deflection (straight down). I removed the belt and inspected that no pulleys were loose. Belt is in good shape. I have heard the accessory bracket can crack, but I don't see any cracks. It seems that the most likely part to have moved is the power steering pump. Could that bracket have bent? Any thoughts? I'm stumped.
