Hi all, I'm trying to flush the coolant on my 2010 Edge AWD. I've noticed a very slow coolant leak that I'm trying to track down, but in the meantime I need to top off the reservoir as it keeps getting lower due to the leak. The fluid appears very dark so I assume it's the factory dark green fluid. I've been reading pages upon pages of what coolants can be used with our Edges and I'm still confused. I just found a Ford bulletin updated last month...
https://www.fcsdchemicalsandlubricants.com/quickref/coolantsEN.pdf
and it now shows DY/DG for our vehicles and says "Either yellow-colored engine coolant approved to Ford specification WSS-M97B57-A1 or WSS-M97B57-A2 (Motorcraft® Yellow Antifreeze/Coolant), dark green-colored engine coolant approved to Ford specification WSS-M97B55-A (Motorcraft® Specialty Green Engine Coolant), or a combination of both engine coolants"
So my main questions are, for a simple top off, what off the shelf brand can I use that could be mixed with the specialty green? I've read Zerex G05 is one that would work, but other than it saying "Ford" on the packaging, I'm not sure where or what I'm looking for that would ensure it actually is compatible with our engines.
Also, the top off is just to get me through the next few days, I plan on doing a full flush and fill in the upcoming week, but I need to figure out where the leak is coming from first.
