You need a harmonic damper puller/installer tool. You can rent them at some auto parts stores like advance auto parts. Jack up the front end and take off the drivers side wheel. Remove some plastic splash shielding, place a jack with a block of wood under the oil pan, remove the upper engine mount, and let the jack down until the engine drops enough so you can get to the pulley from inside the wheel well. Remove the splash shield by the starter motor so you can stick a pry bar through one of the holes on the flex plate (aka the flywheel) to keep the crank from turning. You might need to have someone hold it but I've found you can do it yourself from under the car. Then take out the bolt holding the pulley to the crank. Follow the directions and install the puller on the pulley, then turn the center bolt until it comes off. Clean off any old RTV sealant and oil from the crank nose and key as needed. Replacing the front cover seal is a good idea right now if it's leaking or has a lot of miles on it. It can be a pain to get out and back in, but it's really cheap (less than $10) so it's good insurance. Put the new pulley on and do everything in reverse. You have to put a little bit of new RTV sealant on the key way, and a little bit of oil on the outer hub helps it go in the front cover seal easier. Crank it down until it's seated all the way. Afterward the car should run but you'll need to take it to have a crank position learn procedure done for the computer to run correct ignition timing. Otherwise you'll lose HP and it will idle rougher. Most dealerships charge anywhere from $50-100 for this. And just to warn you, if you don't have the tools/experience/patience for this kind of thing, it's better off not attempting it yourself.
