On most newer cars, the crank pulley is one piece with the harmonic balancer.... Remove it with a harmonic balancer puller.
To remove a crank shaft pulley you need to first jack up the car. Next, remove the bold holding the crack shaft pulley in place and remove the unit. Reverse direction to put the new crank shaft pulley on your car.
12mm /19mm
remove all belts,tensioners etc, remove pulley bolt, use HARMONIC BALENCER PULLEY to remove - DO NOT USE NORMAL PULLEY REMOVER - must be pulled from center of pulley not from outer edge
The crank position sensor is behind the crank pulley. You need to remove the pulley, remove the plastic shield and remove two of the lower front cover bolts. Then you can remove the crank sensor. This proceedure is more complicated than it sounds. Check out the following website for a cam install and scroll down to where it talks about removing the harmonic balancer (crank pulley) http://www.mccgp.com/upgrades/caminstall/caminstall.php Hope this helps.

You have to get a pulley puller of the appropriate size. Without a pulley you have no chance safely to remove it. Be careful do not deform the pulley it's not that hard as you can think.
Loosen the 18mm bolt about 4 or 5 mm and give the bolt a good wack and the pulley should pop. Then remove the bolt and pulley.
There is a large metric bolt right (17 or 18mm) in the center of the main crank pulley. Immobilize the crank using a vise-grip equiped with a locking chain. Wrap an old fan belt (cut-to-size) around the crank and protect the serpentine gooves of the crank pulley, then wrap the vise chain and clamp onto the crank. Use a good breaker bar, or impact hammer to break the bolt torque free counter-clockwise. Note: Don't remove the four 10mm bolts on the crank pulley. The whole thing comes off as one assemble piece.
Impact gun/wrench and a puller
disconnect the battery, remove the bolt in the center of the pulley, then use a harmonic balancer tool to remove it
After removing the right front tire and fender liner, you remove the serpentine belt. You then remove the crank bolt and use a puller to remove the pulley.After removing the right front tire and fender liner, you remove the serpentine belt. You then remove the crank bolt and use a puller to remove the pulley.
Removing the crank pulley requires an impact wrench
Remove anything that may obstruct pulley (belt, wheel, etc.). Your best bet is to use an impact gun to remove bolt in center of pulley (turn counter-clockwise and use safety goggles). After loosening bolt you need to use a harmonic puller to get pulley off crankshaft (do not use impact gun on puller). Tip: Unthread bolt about 1/4 inch from crank pulley then use puller, loosen puller and remove crank bolt a few more turns off crankshaft, then use puller again to slide crank pulley off crank again, keep repeating until it is off.
