If its been over 4-5 years and you live in a area that gets winters, you should look at replacing your belt.
Thanks, but it's actually not the belt I'm worried about. The cracks are in the edge of pulley itself. Looks like it's the crankshaft pulley. Looking a little closer, it might just be cracks in the paint, if it's painted. Can someone take a look at their pulley from above? Does it look the same?
