replace the pulley or the whole assembly
As I was delivering pizzas tonight in ole reliable bonne, I heard a rattle around the passenger side of the engine compartment. I think it is the tensioner pulley. The rattle would stop as soon as I put the car in gear and got above 1500 rpms. When I get to the next delivery or stop light and sit still at 1000 rpms the rattle returned every time, without fail. Should I replace the entire assembly or just the pulley? Keep in mind this is my girl forever and I don't want to have to fix something 2X. Is it normal to have just the pulley go out or is it worth it to avoid any future problems and replace the whole assembly?
