bummer. maybe i will just drain and flush with distilled water until it is clear. drain one last time and refill concentrated coolant to be about 50/50.

is this a drain/flush from radiator lower hose and fill at cap? My coolant is brownish too and was looking to just a full cleanout and refill to try and see if it is still getting contaminated or if they mixed coolants at some point.

Original. Never changed or topped off. Tech told me toyota says coolant is lifetime. Never to change
