how do i fix this?
Yea your not going to like it... You have to get a bolt extractor drill the center of the bolt and use a bolt extractor that has a revers thread as you tighten it it loosens the bolt... Not easy but doable... Do you own a torque wrench?
I wish it was just a broken bolt. What broke was the bearing arm that the pulley fits on to. The bolt threads into this holding the pulley in place. Tomorrow I'll attach a photo. I'm afraid I'll need to replace the entire front plate of the engine.
