I flushed and drained coolant from bottom Radiator Hose and was only able to get 4 quarts pure universal coolant and 1 quart 50/50 (4.5 equivalent quarts of coolant)with some spillage. I worked hard getting that in (ie. several bleed and burps). This included filling the overflow reservoir to the hot level. The system holds 12.3 quarts and based on my calculations I now have a .33 percent mix shy of the 50/50 mix recommended. Any explanations, comments or recommendations. It appears to run great at 180 degrees.
