I did my stage 1 this weekend, and turned the drain valve 90 degrees (Max Limit) removed the system cap (radiator cap) and did all that I knew how to do to the damned thing & there was no way that even a drop of fluid came out. Fortunately the cruiser was up on the lift, so I removed the lower radiator hose to drain the system. Drained it all, & installed fresh coolant. [:I]
