If you use green coolant you can add something with SCA's. I've used Winns before. In my 4610 SU I use the Ford FW15. Here is a Motorcraft version.

As I had to remove the radiator in my 2003 Terminator, First time change in 14 Years, This time I used Royal Purple Purple Ice. Old Antifreeze still seemed fine. From what I could see, there was absolutely no corrosion or sludge in the cooling system or jackets. Steel cooling lines were shiny metal internally also.
