FWIW, I've always used my 450ft.lbs. impact wrench for them and never had a problem. Always came off with ease. Since thats not even really that powerful of an impact, it honestly shouldn't be that hard to get off. The last time I had to pull mine off I didn't have any air tools so I put my spare tire wrench in the teeth on the flexplate and used a breaker bar with a pipe on the end of it on the crank bolt and with a little bit of convincing it came right off.

When I do them without my 625 ft-lb impact wrench, I lock the flexplate by removing the plastic cover (couple of 10mm head bolts) and slipping a BIG round phillips through one of the holes in the flex plate, then rotating the crank until it is jammed up against the block. That holds the crank in position.

I have always jacked up the car, removed the RF wheel and inner fender plastic to get a straight shot onto the pulley bolt with my impact wrench, or with hand tools. I don't think you want to try to jam the crank pulley 'cuz I think that might damage the rubber joint between the pulley and the hub of the HB, and they are about $100.

I don't know if you will have room to get a big wrench on the crank pulley nut,without removing the wheel, but you definitely need the correct socket, preferably 6-point, some sort of extension, a stout handle and a long cheater bar (mine is 4-feet).

You've gotta get the serpentine belt off, too.

After the bolt is out, you will need a harmonic balancer puller with some 6mm bolts just the right length (~3in?) to attach the puller to the HB to pull it off. Crank sensor is under pulley at the 4 O'Clock position. Disconnect electrical connection, unsnap plastic cover and unbolt 10mm bolts. Sensor out.

No way you are gonna do this without tools.

THANKS BILL

I owe you one. All said and done, it was rougly an hour between the time that Bill arrived and the time we went back inside to warm up, that also included the trip to the parts store. About a half hour of actual labor.
