I'm not drinking the life-time coolant fluid. Just did a quick coolant flush and the old stuff looked very light blue vs. the new 50/50 coolant to distilled watr ratio.

Radiator drain plug is on driver's side. Turn blue plug CCW until removed. Then put a 7/8 socket on the plastic nut which only turns 90 degrees CCW. Went to top of radiator and unscrewed cap which released the coolant at the bottom of the drain plug area. 3/4 of a gallon was released. Filled and bled system. Will repeat in a couple of days emptying the entire system.
