I have a bad pulley on a '96 Corsica tensioner. I see that I can replace the pulley, but can it be done without removing the tensioner? It looks like the pulley has spun out of the bearing. I can't see down in there very well, and I can't see a bolt to remove the pulley so it's either hidden from view right now, or on the back side of the tensioner. If it is on the back side, I don't see any way of replacing it without pulling the tensioner which may mean pulling out the motor mount and/or water pump first just to get a damn wrench on it. If I have to do all of that it makes more sense just to replace the whole assembly.
Does anyone have any experience with this? The same tensioner seems to fit a number of 3.1L GM autos.
Thanks.
