I did it 2 yrs ago.... but I believe so.... DL adobe and take a look

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
A: REMOVAL
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
CRANKSHAFT PULLEY WRENCH
3) Remove the crankshaft pulley.
B: INSTALLATION
1) Install the crankshaft pulley.
2) Install the pulley bolt.
To lock the crankshaft, use ST.

WRENCH
(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).
CAUTION:
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
gun.
(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
degrees.
CAUTION:
Conduct the tightening procedures by confirming
the turning angle of the crankshaft pulley
bolt referring to the gauge indicated on the belt
cover.
4) Install the A/C belt tensioner.
Crankshaft pulley bolt:
5) Install the A/C belt.
C: INSPECTION
1) Make sure the V-belt is not worn or otherwise
damaged.
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.

thanks for the help finally got it 160 psi and 40 minutes with an impact gun got it off.

thanks

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
