what to do about a stripped crankshaft pulley bolt do i go up to the next size bolt
i retapped the hole with 12mm tap but the bolt is sloppy doesnt seem to tighten properly and i dont know if a helicoil is strong enough to fix this problem or is there another solution>
A helicoil repair should be 'man' enough for the job, just remember not to overtighten the pulley bolt. Always refer to manufacturers tightening torques.
ya helicoils are great,remember 2 use loctite
