Are you sure you are having an overheating problem, and not just a foaming and loss of coolant issue. I had a similar problem with foaming and it turned out to be the combination of the antifreeze I was using and some preventative radiator sealant. Flushed everything out and replaced with 50/50 green Prestone. Problem solved. Do not fill above core tops. Check with meat thermometer or H/F infrared sensor. Maybe you will get lucky like I did and not have to go into the engine right away.
