I have a 2009 Acadia that has recently began smoking under the hood. It seems to be puddling one the drivers side of motor. Smells like antifreeze, but has color of transmission fluid. Oil does not seem to have any antifreeze in it, however the engine will overheat very rapidly. Transmission and coolant levels were low and refilled without change. I am including some pictures of leak below. I would appreciate any help.
