Hi,

These are torque to yield bolts and CANNOT ever be reused as they will not hold their torque.

From KIA service manual

KMA has received some questions regarding the proper torquing of the Crankshaft Pulley Bolt. The bolt and washer should be replaced every time the bolt and washer are removed and SHOULD NOT BE RE-USED. This bolt and washer must be torqued to 130 lbs. ft. (176 Nm) by hand using a properly calibrated torque wrench. The flywheel must be held stationary while the bolt is being torqued. Under NO circumstances should the bolt be installed using an air impact gun!

Have your mechanic install a new bolt and washer, remove the starter and install a flywheel holder and tighten using a torque wrench, NOT an impact gun. Tightening with an impact gun can stretch the threads on both the bolt and the threads in the crankshaft itself.

If the bolt comes loose again, then the threads in the crankshaft were stretched from the over torquing of the bolt previously and the crankshaft has to be replaced.

If for any reason, you can't rate my answer OKAY, GOOD, or EXCELLENT/3 STARS OR HIGHER today. Please reply and let me know why, so I can help more/better. All follow up responses are FREE, after completing the required rating
