First, to provide a little background. My sister went to start her 1990 Cadillac Deville one morning. The vehicle was emitting a very obnixous squealing sound and a very strong burning odor. I took the belt off to look at the pulleys. It appears as if one of the pulleys is seized. My first impression is that this is the water pump pulley, however, I am not certain. I have a few questions that I would greatly appreciate any help with.
- The pulley that appears seized (does not want to rotate by hand), is circled in the attached photo. I have also circled it in the routing diagram. I was thinking this was the water pump pulley; can anyone confirm or deny?
- There was another pulley (one of three that is above the highlighted one in the routing diagram) that had “shreds” of the belt on it. However, this pulley appeared to turn pretty easily by hand. Is it possible that the stuck pulley resulted in this one shredding the belt, or is it likely to be defective as well.
- This may be a stupid question, but is there any way to clean/repair the pulley, or is replacement the only option?
- Finally, while I am not an expert, it appears as it some fluid was leaking on the pulley, possibly causing its death. Based upon the location of the pulley, what is the likely culprit?
Thanks much for any assistance.
