Use an impact wrench. The 3/8 inch models do not have enough torque for this job so use a 1/2 in wrench. Jam the belt with a piece of wood so the pulley doesn't turn. Use an socket designed for an impact wrench, which has a tighter fit on the crankshaft (or "harmonic balancer") bolt head than a socket meant for a hand tool. This will keep you from marring the bolt head. The bolt is threaded normally, not reverse threaded.
I am a believer in using hand tools wherever possible. The service manual shows the use of a special hand tool. It is a semi-circular piece of metal attached to a handle. The semicircle is attached to the crankshaft pulley by two bolts that go through two holes that you can see in the pulley. The idea is to hold the pulley with this tool. The semicircle leaves the pulley bolt exposed so you can put a wrench over it and turn it. However it would be hard to find this tool for sale in the USA. To losen the pulley bolt you will need a breaker bar with a long extension. If you have the car up on a lift then you have room for a long handle, but if you have it on jackstands you won't. My conclusion is that the impact wrench is the practical way.
