Just did mine...took about 4-5 hours. I had to remove my radiator; it's a dual core and got in the way...removing it also allowed me to use Mr. Air Impact Wrench on the crank bolt
I just tapped the damper off with a rubber hammer...came off easy, but you
may need a puller.
The lower timing cover can be a PITA...there's a small weep hole in the bottom, I got a small screwdriver and pried there 1st to get it started. Do a good inspection of your belt tensioning pulley, the crank timing belt gear, and associated keyways.
I replaced all my belts, since they have to come off anyway. It's critical to get the timing marks lined up on their respective indexes like Nick said. The keyways will also line up on an index just above the crank timing belt gear...it matches the damper index on the zero mark on the lower timing cover.
The stock damper should tap back on easily...use some anti-seize compound on the inside of the damper where it slips over the crank. Make sure to torque the damper to spec...it's a lot...195 ft/lbs!
