Ford 6.7 Powerstroke Coolant Drain & Refill Primary & Secondary System How-To

This video will show you how to drain and refill the primary and secondary coolant systems on the Ford 6.7 Powerstroke diesel and also shows you how to drain the engine block as well. This was done on a 2015 F-350 but should be the same procedure for the 2011-2022 F-250, F-350, and F-450 Superdutys. Ford and motorcraft has discontinued the orange coolant that originally came in the 6.7 powerstroke diesel and replaced it with the Motorcraft VC-13-G yellow coolant. Ford claims you can mix the yellow with the original orange without any issues. I purchased the coolant from Amazon and provided a link below. To do this entire job you should at least buy a minimum of five gallons of coolant concentrate and mix 50/50 with five gallons of distilled water only. Ford also recommends using a vacuum coolant system refilling tool to prevent air pockets and cavitation in the cooling system. I will also provide a link below to the tool I used in the video which worked very well.
