I have a 2017 edge titanium. It wouldn't start and I noticed there was no coolant in the resevoir. I checked the dip stick and noticed it was really high and it was orange.
Am I looking at an engine replacement or just a head gasket? Thanks for ya'lls help

 

Since you caught it in time ,,,,,,until a further check is done , I wouldn't jump to any conclusion.

If only a head gasket, fairly common,,, can be a lot cheaper to correct. Sometime they leak at the intake manifold.
Removing the spark plugs should reveal if it is getting into the combustion chamber., plus notice any white smoke from the exhaust?
What does the oil fill cap look like underneath? If soupy, yeah, it's getting into the oil alright .
