Recently changed out my heater control valve in my '95. Ran it up to temp and antifreeze/water began dumping from high up on the engine drivers side. Today i removed front wheel to check if my heater hose had come loose, it had not. While out there i decided to bypass the rear heater. Started the truck ran it up to temp and same thing. I can not tell exactly where it is coming from. Any help on what to pull or to check? Am i looking at a cracked head?
