Thankyou.In a diesel it's VERY important to run exactly the kind of anti-freeze the factory tells you to. Yes, it costs more but bad things could happen if you don't.
And to add to it there are different kinds depending on the year. So you have to make sure to have the correct test strips.The 6.7's, 2011 and up, Do Not use standard anti-freeze. Instead they use a hi-tech coolant that has additives such as lubricants and anti-oxidizers. Test strips are available to maintain proper ratios of each component. While you can do whatever you want, you do take a chance of ruining your block!
Must you run the ford brand antifreeze to keep from voiding the warranty. What does everyone else run in your 6.7 2017
