6.7 Coolant?
I know Ford used the orange extended life coolant in the 11-17 trucks. And it appears Ford has added more confusion by changing the coolant color once again for the newer trucks. Before anyone says anything I know, don't add coolant based on color alone follow the proper specs.
In the video below Tom briefly talks about Organic Coolants. Is this new "Yellow Coolant" Ford is using in the new 6.7's the organic coolant referred to below? Can the earlier 6.7l engine coolant be flushed and then use this new "Yellow Coolant" without fear of gasket failure or any other problems? It appears this new organic coolant doesn't require testing like the orange coolant does.

I have the same question if a flush is performed, will the yellow be ok. The change was in the mid 2019 models and not earlier.

Ford says the 2 coolants are compatible but does not recommend mixing them. Here is a thread from the 17+ forums
