Coolant flush procedure
I know For has a 6.0 L Diesel cooling system contamination flush procedure, but what about the shops that have the machines that vacuum or however they do it? Has anyone ever used that? Also Fords procedure talks about using VC-9 but doesn't say anything about Restore. Any input on the procedure of using them both? Switching to the ELC and shop owner says he has that machine and it should be easier. I just wanted to know if I still need 22-24 gallons of distilled water, 2 quarts of VC-9, and 1 gallon of restore if using the machine?
