Did the drain and fill today. Got Menard's Coolant today for $3.49 a gallon after MIR. Label is word for word to the PEAK green and I read somewhere that Old World Industries makes both brands anyways. Ingredients list is identical too. Radiator drain ended up dumping out a gallon and a half of ugly old coolant. I then took off the lower radiator hose and got maybe a half quart to a quart more [censored] outta there. I refilled the reservoir with 1 gallon mixed 50/50 with distilled and used half of the 2nd mixed up gallon. Ran heat on full blast for about 10 minutes and took a small run around the block to be sure she was pushing the coolant well. Let it cool for an hour and topped it off to the cold fill line. All is well.
