Flush went well. Couldn’t get to the petcock, even with plyers. So you a technique from YouTube to unplug the line that pumps the fluid into the reservoir tank and run the car to drain it.
Put 2.5 gallons of distilled thru the system. Then added the coolant.
Old coolant looked pretty good compared to what I saw online. But it did look like the previous owner or pre owned dealership topped it off with green coolant at some point w/ the orange.
