Your online manual says the following:
Engine coolant (U.S. and Mexico): Motorcraft® Yellow Prediluted Antifreeze/Coolant VC-13DL-G WSS-M97B57-A2
Engine coolant (Canada): Motorcraft® Yellow Prediluted Antifreeze/Coolant CVC-13DL-G WSS-M97B57-A2
Of course that's what it says, that way Motorcraft can stay in the fluids replacement biz.....
But the reality is that any orange or yellow stuff from name brands like Prestone, Zerex, or Peak will work fine,
as long as it is of the "DEXCOOL" variety, which meets almost all mfgr's specs for vehicles from ~2012 & later....
i've been using that stuff in all my vehicles since about 2008 or so, neveranottaproblemo
Most people do prefer the pre-diltued type, since it is less fuss, but the mixer type is fine also as long as you mix it 50/50 with distilled water before adding to your system....
If your engine coolant is low and needs to be topped-off, you have a leak (unless you recently had service and the correct amount was not installed).
UNLESS you have been driving in very hot climate with the AC running at full blast for extended periods of time, or hauling heavy loads thru the mountains for a long while, or something to that effect....
Those situations will sometimes cause
some coolant to be used from the reservoir, but yea, if both the reservoir & the radiator are low, then there very well COULD be a leak somewhere....
