Is the bolt in the center of the crankshaft pulley right hand or left hand thread for a 1993 Geo storm 1.6L engine?

If you are looking at the pulley, the engine turns clockwise.

Its been over 10 Years since the pulley was replaced, by NAPA mechanics.

Something wrong with pulley? Or is this preventative maintenance? Someone recently asked the same question.

Having problems getting bolt off. To change the timing belt you must remove the crankshaft pulley. I believe the nice folks at NAPA probably used some sort of locktite.

If they did it would possibly indicate right hand thread? Since the direction of rotation favors the logical choice of self tightening left hand thread? Left hand is really rare anyway. The cost alone would probably prohibit it in any low price car.
