You might try to use ball valves. I do remember my 07 had ball valves. As I said earlier I talked to someone at the Nibco valve company here in Nac. and they sorta didn't know about the coolant. They make all sizes of valves from water to large oil field valves. I don't know why they would not work. I just had very little time to make up my mind. If you do use ball valves I would certainly use made in USA.
