I had a bolt head shear on a bracket that held the 2 hard lines going into the Expansion Valve releasing the entire contents of my cooling system, I am hoping this will be a simple fix but a strange one indeed and just wanted to give you guys a heads up! In the diagram the "Screw" is labeled number 34 and is an M6 X 16 cap head and the other 2 circled parts number 31 and 28 are the O-rings that are nowhere to be found! The second pic is of the bracket that holds down the hard lines in the expansion valve and the failed screw sits on the other side of this hard line.
