Answers :

If you mean the bottom pulley on the crank, I would suspect the rubber is coming unglued from the steel and so it should be replaced. If you mean the main pulley where the fan is mounted I would look to see if maybe the 4 bolts there have worked loose. Failing that the water pump is most likely bad and will need replacing. Hope this helps.
