Default anyone ever had their fan pulley bolt back out???

it has happened to me twice now...

fan/AC/alternator pulley that runs off the main crank has a m14x30mm or something along those lines

i had torqued to over 90 lb-ft with thread locker... the spec is 135 lb-ft torque but my wrench does not measure accurately any higher.

i suspect that when my car backfires it causes the motor to spin the other way... any thoughts???

My manual says: V-belt pulley to crankshaft (M14 x 1.5) - 173 ft/lb so you are under-torquing it and need a bigger wrench!
