Question about Cars & Trucks
First YOU will need a pulley puller its a three prong device for pulling pulleys without damaging it. A long allen-head bolt should be inserted into the crankshaft so the jaws of the puller only contact the hub of the pulley- not the outer ring. The pullers tapered tip should push against bolt to prevent damage to the crankshaft threads. You may be able to get a press on sleeve to renew the sealing surface if its been grooved from long time contact with the seal. It is pressed on with hammer and block of wood. To replace the pulley you will need a vibration damper installation tool. Lubricate the pulley hub with clean engine oil. Align the slot on the pulley with the key on the crankshaft and push the pulley on crankshaft as far as it will go. BE careful not to bend the outer ring of the pulley. Now you will need the vibration tool to press the pulley the rest of the way onto the crankshaft. Install the crankshaft pulley retaining bolt and tighten to the torque listed in the owners manual or get a repair manual with the torque tightness listed. I'm good but not good enough to know all the torque specs on every vehicle. Hope that Helps! The crankshaft pulley is the bottom pulley NORMALLY.

SOURCE: broken crankshaft pulley bolt on
The only possibility I can suggest is that which is called and 'Easyout.' These are available at parts stores and come (normally) with a sized drill and a special bit with left-hand threads.
First a hole is drilled with the provided drill bit, then the removal bit is screwed into the new hole and turned counter-clockwise which further inserts the removal bit and, if the removal bit does not snap, the broken threaded shank should back out.
I would suggest soaking the broken part with penetrating lubricant first and allowing it time to seep into the threads of the broken bolt.

Somethimes this happens over time. It is usualy caused by an oil leak at or above the pully causing the rubber in the "hamonic balancer" which is part of that pully system to fail. If you don't have it repaired you will find the pully will wear through the cover behind it. So be sure to get it repaired.
Hope this helps, Good luck.
