I just finished with the same problem. You are leaking coolant out of the plastic coolant elbows. They are located at the bottom of the belt tensioner bracket, and go into the water pump and lower intake manifold. You have to remove the belt, alternator, and belt tensioner. The two elbows were $4.24 at a NAPA auto parts. It took about 2 hours because I dropped a couple sockets and had to retrieve them. Overall not very hard.
