What is your question?
have recently purchased a 1999 3500 chevrolet truck... previous owner noticed coolant leaking from bottom area of the inlet manifold. He had purchased a gasket set. I noticed that the engine coolant looked green (not the color of dexcool) could this be the root cause of the leaking manifold.. material incompatability? any suggestions on what to do next? drain the green stuff and put in dexcool? Currently block dry but shows white deposits where it was leaking...

GM used Dexcool as a "long life" antifreeze coolant but have had numerous problem with it. I would thoroughly flush the cooling system and refill with a reputable known brand antifreeze.
They do sell coolant that mixes with all makes and models and it is green in color. A flush and fill would be best, after the gasket leak is repaired.
