-- When I first pulled a bolt, without draining any coolant, I pulled the one on the top of the passenger side first, and no coolant came out , with the bolt completely out. ( the coolant was completely full, up to the radiator cap). -- This makes Me believe that that bolt does not go into the water jacket. -- See post # 3, and 5. By testing that is apparently the situation - 3 bolts in water. -- I did not pull the 3rd , wet bolt, because it is under the fan pulley.
