SMK - I'm stumped about the fluid that's gone from brown to clear? Which side of the engine bay? - passenger or drivers?

The hose I was talking about earlier goes from your rad. to your expansion tank. The one you mentioned in you last post is where the coolant flows to when you have a boil-over situation.
