2001 s80 t6. There is no water/oil mixture, no white smoke, no external water leaks but im losing water slowly and have a random missfire as well as bubbling in the coolant resevior. temp gauge reads slightly above middle and fan funs. Any ideas??????? Im about to pull the plugs now to see if I see any green coolant tint on them. I just replaced them 2 months ago so I know they are good.

RConsider replacing the expansion tank cap also. Cheap insurance for something that will cause issues similar to what you are experiencing. Misfire may be unrelated, hard to say. A cooling system pressure test is a good idea if you are loosing coolant.
