    I for the life of me can't remember but logically, if it were me designing (people reading this are vomiting about now...) I'd use the direction of pulley rotation to go "with" the bolt so that as the motor spins, the bolt cannot loosen. Here's the manual except; I see no special mention but you are fighting almost 100 ft. lbs. of torque, aging, and maybe Murphy's law:

    13.Crankshaft Pulley
    1) Remove the V-belt. <Ref. to ME(D0HC TURBO)-
    44, REMOVAL, V-belt.>
    2) Remove the crankshaft pulley bolt. To lock
    crankshaft, use ST.
    ST 499977300
    3) Remove the crankshaft pulley.
    1) Install the crankshaft pulley.
    2) Install the pulley bolt.
    To lock the crankshaft, use ST.
    (1) Clean the crankshaft pulley thread using an
    air gun.
    (2) Apply engine oil to the crankshaft pulley bolt
    seat and thread.
    (3) Tighten the bolts temporarily with tightening
    torque of 44 Nom (4.5 kgf-m, 33 ft-lb).
    (4) Tighten the crankshaft pulley bolts.
    Tightening torque:
    127 N-m (13 kgf-m, 94.0 ft-lb)
    3) Confirm that the tightening angle of the crankshaft
    pulley bolt is 45 degrees or more. If not, conduct
    the following procedures (1) through (4).
    If the tightening angle of crankshaft pulley bolt
    is less than 45 degrees, the bolt should be damaged.
    In this case, the bolt must be replaced.
    (1) Replace the crankshaft pulley bolts and
    clean them.
    (2) Clean the crankshaft thread using an air
    (3) Tighten the bolts temporarily with tightening
    torque of 44 N.m (4.5 kgf-m, 33 ft-lb).
    (4) Tighten the crankshaft pulley bolts keeping
    them in an angle between 65 degrees and 75
    Conduct the tightening procedures by confirming
    the turning angle of the crankshaft pulley
    bolt referring to the gauge indicated on the belt
    4) Install the A/C belt tensioner.
    Crankshaft pulley bolt:
    5) Install the A/C belt.
    1) Make sure the V-belt is not worn or otherwise
    2) Check the tension of the belt. <Ref. to
    ME(D0HC TURBO)-45, INSPECTION, V-belt.>

    EDIT: The bearded fellow in the video did "lefty-loosey" so the bolt is conventional apparently. Makes sense.

    Use this as a reference. I believe it's included pzr2874's response.

    I did it like the video about showed. Breaker bar and a steel pipe. Give it a shot.

    Good luck, T.J.

    The easiest way to do it is with a breaker bar on the ground, unplug injectors, turn over the motor a couple times. That thing will come right off faster than you can get your air tools on it.

    Not recommended. lol
