I was reading that mixing the universal green with hoat can cause sludge, well when I bought mine it had the green and when pulled apart for rebuilding the heads it definatly had some sludge, I'd like to convert it back to hoat but don't want to create even more sludge in it. Should I have a coolant flush preformed and then put the hoat in it or would I be okay just draining it and refilling?
