I went through this same thing earlier this summer... It turned out to be a leaking gasket (<$1.00) between the water pump housing and the block. The repair itself was simple, but getting to the repair was rather involved. It involves removing the radiator hoses, radiator, fan shroud, fan, belts, and water pump. Beware: the bottom bolt on the water pump requires an extremely shallow 13mm socket, or an offset wrench - I chose to grind down a socket on the bench grinder. I figured since I had this much already torn down, I would go ahead and replace all of the under hood rubber - 4 belts and 14 hoses. The procedure is not complicated if you don't mind the time it takes to perform it. Hope this helps - Raven
