macbwt Posted October 3, 2020 Report Share Posted October 3, 2020 Got rid of the corrosive orange and went with the Peak 10X. Why? Because Ford put out documentation to flush it out and replace it with yellow. Quote Link to comment Share on other sites More sharing options...
Sage Posted October 3, 2020 Report Share Posted October 3, 2020 I have read a lot about changing it out on the 2.0, but could not find anything on the 2.7. Does that apply to the 2.7 as well, as I have the orange looking in my ST. 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted October 4, 2020 Report Share Posted October 4, 2020 At least on the 2015 2.7, you do have to use the same method: https://drive.google.com/file/d/1nKNbBf3zhikn00ZJUb3Z1xqQCiTkR28t/view?usp=sharing Quote Link to comment Share on other sites More sharing options...
handfiler Posted October 4, 2020 Report Share Posted October 4, 2020 (edited) I bought a kit similar to this in preparation for the supercharger installation on my Mustang. Vacuum Cooling System Filler Kit I'm glad I did as it made the refill process of the cooling and intercooler systems a breeze. It's nice knowing your system will be 100% filled and purged of all air in minutes without having to start the vehicle. ?

todd92 Posted October 4, 2020 Report Share Posted October 4, 2020 (edited) The orange is NOT corrosive. Ford does NOT recommend replacing the orange with yellow early. The yellow has double the service life of the the orange, which is why the orange was replaced with the yellow. There is NO need to run out and flush the orange out of the vehicle.
