Best way to drain/change the coolant?

[JOHNDQ]

Trouble is the thermostat wont open till 88 degrees, I your putting cold water back in then it wont ever open. Maybe try flushing though the system with a hose, run it up, drain it and do that again when drain it again should get more less all of it I guess. Obviously don't put cold water into a hot engine

Yeah that makes sense, I could just do it over the course of a few days, fill it and empty it till it runs clear.
