I can think of 3 possibles; It may be a hardware store replacement bolt, & the original bolt might have been a grade 8. Secondly, that is one of the bolts I would use a torque wrench to tighten, following whatever the torque listing was in the tech manual. Lastly, could there be a damaged pulley, like a bent camshaft or water pump pulley, or something jammed in one of the cogs a pulley with teeth? On my 94 1.9 that would be the crankshaft pulley, water pump pulley, and camshaft pulley. ?
