Ford switched from ORANGE to GREEN coolant 18 > 19...any reason to flush an 18 to green?

Or should the 17 and 18 owners continue to use the orange coolant?

My 19 is orange...make that **** yellow with a hint of blood.

Just double checked, it's yellow for sure.

The new ford yellow is more robust compared to orange, it is now factory fill on almost if not all fords. I have changed out my other ford orange vehicles to the new ford yellow. It is a POAT coolant vs orange being OAT. longer life and better corrosion protection.

make sure to completely flush the system a couple times and fill with the proper ratio to end up around 50/50
