I have a 2017 5.0L S-crew. I was getting ready to do a quick coolant flush (just draining the radiator and refilling) and the dealer told me the coolant has changed. My owners manual gives a part number of VC-3DIL-B which is the orange coolant that came from the factory. The dealer told me that Ford changed and the part number is now VC-13DL-G which is a yellow coolant. The shop guys told me both fluids are compatible with each other.

Anyone else come across this yet?

 

Yes, and all that is true. Yellow replaces the orange, both compatible and can top up orange with yellow.

 

Thanks!

Thanks all. I was hoping there was a published service update floating around somewhere.

 

Yes, I too just had a Whipple installed and the coolant has been changed to the yellow coolant.

Had mine done in January when they did the block heater fix (Switched to yellow coolant). Had to convince my dealer to make the switch according the the TSB at that time. The procedure to change over is detailed in that letter as well as tmcolegr mentioned.
