I had similar issues with my 200. It would overheat, so I stopped driving it during the summer (it’s 95-110 where I live outside LA). I came across a Mustang and Ford article about cooling systems and came across Evans Waterless Coolant. I never took the plunge because the cost is anything but cheap (flush kit is about $100 and the coolant runs about $45/gallon). However, after getting sick of the overheating, I started talking to some other Mustang owners and hot rodders (they mentioned the waterless coolant as well) and after asking if it’s all it’s cracked up to be, I was simply told, “It’s worth it’s weight in gold.”
I took the plunge and did a 6 cyl AC fan, 2 row aluminum radiator, 180 thermostat, and converted it over. I haven’t had an overheating issue since. What sold me on the coolant wasn’t it’s heat transfer capability (it’s on par with 100% water), but the fact it doesn’t build pressure either. The hottest I’ve been able to get my car to run is 192 with a infrared gun point right at the thermostat housing. By the time the coolant hits the lower rad hose, it’s around 174. No need for an overflow tank or anything. It sounds like snake oil, but I’m right here with the people who told me about it. It’s absolutely worth it. I’ve attached a link to the article as well. Hope this helps.
