I don’t have any on hand so what I have done so far is started disconnecting hoses and flushing stuff out till it runs clear, then flushed some more. Now I filled it up with water and am running engine for a while. Will then flush it again. I have some Prestone flush that I will put in it since that is what I have. I will then flush it again. Drain then pull back into shop and wait for new thermostat to arrive then fill with g05. I thought I had a new thermostat around here but all I can find are used ones.
