Not sure, I have a 7.3 and I get mine from O'Riely's in pint bottles. Had to go out to the shop and grab one..
It's Motorcraft Diesel cooling system additive. It's ESN-M99B169A and they have it in stock for (I think) 6 bucks a bottle.
You will need a Ph test kit to check the SCA level. I use a Fleetguard test kit myself.
I have also used Cummins DCA-4 which is available at any heavy truck dealership but again you need to do a PH test on the coolant after adding and allowing it to circulate in the motor for a while.
Not a problem with circulation on my 7.3 because I added an external spin on coolant filter so the coolant is always circulating even when the motor is cold and the T'stat hasn't opened.
I added one bottle of the Ford additive this summer and checked the Ph and it was within spec. I just happened to buy 4 bottles at one time.
The additive level wll drop with engine heat and cool cycles so it's not a one time add. I check mine every oil change.
Finally, replace the coolant tank cap at least once a year. They fail in time and the cooling system looses pressure and you can develop hot spots in the block, a bad thing. Chap too. 6 bucks is a lot cheaper than a motor rebuild.
Hope that helps.
Better add that Ford also offers a test kit...328-2050-62291 or 328-20503R but the Fleetguard test kit is less expensive and does the same task. The Fleetguard kit will be available at any heavy truck dealership as well
According to my bottle that I'm looking at, VC8 and the above numbers I listed are the same thing.
