Ok, so I did a little searching and found the Ford bulletin I was referring to and got the part numbers for the cleaner and cooling system conditioner which I think is just a stop-leak additive. The part number for the cleaner is Motorcraft # F8AZ-19A503-AA and the conditioner is FW-16. I did some looking online and it is difficult to obtain the motorcraft cleaner, but it is available. From what I found during looking around on the web it further reinforces my speculation that the cleaner used in the bulletin is also much stronger than what you can find on the parts shelf anywhere else.
