Today I went and looked at this old ladies 96 240sx and it's in great condition except for this squealing noise coming from a pulley that I have pointed to in that picture below(not the same car as I looked at today, just using pic to show) My thoughts are that it's just a loose pulley, I checked the belt and it seemed firm but I couldn't move the pulley with my finger. I might still buy this car if anyone hear can tell me a little more about this problem.
