Might I suggest putting your valves near the engine supply and return rather than the filter head. In that manner, it allows you to change hoses if they become damaged in some manner. It is true that you will loose a cup or two of coolant every time you change filters. Check to see if your filter supplier has coolant test strips so you can keep a check on your molybdate and nitrite levels for optimum corrosion protection.
