It's not all that tough. The hardest parts are getting the crank pulley bolt off and lining up the timing belt/crank/cam correctly. You'd need to follow the directions carefully if you've never done the job before. It's fairly tedious work as well. BE SURE you do the tensioner and water pump at the same time. It's all connected/run by the timing belt so you might as well do those while you have the timing belt off.
