I have decided to flush the Oasis system. I pulled a sample and got it out in the light and it looks like weak coffee. It test to -18F for antifreeze/cooling properties. Using a digital ph probe the ph is 5.5(acidic) and the ph should be 9-9.5(basic). I plan to flush the system with fresh water thoroughly and then blow it out eith air to get the bulk of the water out before reintroducing the coolant. Does this sound about right to everyone?
