I know the truck takes the new Ford Yellow 50/50 Antifreeze coolant and I went ahead and topped off the reservoir with it, but now I'm thinking I probably should've flushed the old coolant which is probably the orange stuff and just refilled with the yellow instead of topping off?
I've a 2019 6.7 powerstroke as well that is below half on the coolant that I was going to top off also, but I'm pretty sure that one has green in it.

Question is, does mixing the orange existing coolant and the new yellow coolant cause problems? I guess if so then i'll need to flush the raptor and refill it entirely. Same question for the powerstroke, will topping it off with yellow cause any issues if it's already got green in the reservoir?
