Hi all,
Looking for some recommendations on a coolant additive, if any, for my 2017 Fiesta ST. The car overheated under normal conditions last night and I'd like to avoid that as we move into summer. It was 97F out and I headed up a hill on my way home after sitting in stop and go traffic for about 30 minutes. At the top of the hill, the coolant temp light came on (this does not come on unless the coolant gets to 245F if memory serves) and the car went into limp mode.
My first thought is that, while working on the car this weekend, some air got into the system, so I'm going to try to burp and refill as much as I can this evening. After that, as extra insurance, what would folks recommend as an additive to keep temps down, if any? The Fiesta ST has a notoriously poor cooling system and overheats even under normal conditions are fairly common. I have upgraded the intercooler but am not interested in adding an oil cooler or changing out the radiator on a car with 16,000 miles on the clock.
I have historically had good luck with Redline's "Water Wetter," but have read about this not getting along well with and sludging up modern coolants. The coolant in the car is the factory fill Motorcraft "Orange," which I understand is identical to DexCool.
Any thoughts?
Thanks!
