The orange is apparently compatible to Ford's WSS-M97B44-D2, as well as GM 6277M (dexcool) and ASTM D 3306.
A while back I couldn't find it so filled one of those generic red "use for any car" coolants, Purolator's Puroguard. While I couldn't find a spec for it online and was in too much of a hurry to note what specific spec, that time.
Should I drain and refill with orange, or leave it? I don't see my car (2014 Fiesta with a 1.5 duratorq aka powerstroke engine) overheating or such, so far in the past month or so I've used it.
