Cloudy Radiator Coolant (After Flushing)

What helped a lot with the radiator running slightly to the warm side, was installing a fluid overflow tank and replacing the lever cap with a standard one (since it has an overflow hose, it works best with a standard cap.) Even a homeade tank works, I used a small empty juice bottle strapped to the fan shroud. I will flush it, but at least one problem is down.
