Keith Browning Posted January 23, 2021 Share Posted January 23, 2021 Has anyone located information on testing the new Yellow coolant anti-corrosion inhibitor - how/what to use and is there an additive available? Quote Link to comment Share on other sites More sharing options...
8WA Sman Posted January 25, 2021 Share Posted January 25, 2021 Keith, I have been meaning to call Acustrip for awhile...So according to them the Ford Yellow is an OAT coolant with Phosphate added, so the 40240 test strips that I have will still work.

Keith Browning Posted January 26, 2021 Author Share Posted January 26, 2021 That is my assumption but seeing something in print would be nice... I still have yet to see an additive which I assume would be the same or similar to the Orange Coolant Revitalizer but again, nothing as of yet.

8WA Sman Posted February 2, 2021 Share Posted February 2, 2021 Kieth, Since I have never used the Orange Coolant Revitalizer do you know if it does anything to restore the PH? Most of my testing on the OE coolant has shown the inhibitor at or near 100% but the PH has shifted so I just replace the coolant. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted February 3, 2021 Author Share Posted February 3, 2021 I don't think I have ever seen documentation regarding what it actually does/contains. To see if it has any effect on Ph you would have to get that coolant recirculating and mix the added product completely and re-test. I suppose if I had one as a personal vehicle that would provide the opportunity to re-test but not on a customer's truck. Quote Link to comment Share on other sites More sharing options...
