there are many machines and last I heard Ford does not make a dealer buy the Rotunda version or any brand for that mater.

but the quality machines exchange old for new so you don't get cross contamination from the machine

I also know on the 5r if it was not up to temp even a hot fluid flush may not be as through as it could be and keeping the truck up to the temp that the cooler is fully in play is hard
