Hi, Finally got around to completing the project today. All went well until I opened up the coolant valve. No coolant! There was plenty of odd sounds and bubbling but no coolant. The problem was solved by putting a second needle valve into the system. This valve went between the solenoid valve and the mixer block. All I can think of is that the water needed more air pressure than the air stream to force it through the system. Anyone else come across this?
