I'm sure theres others but you have to be very careful which kind you use as some are very corrosive in these engines.

I my self am using the Motorcraft.

There are many threads on this topic already, just trying searching "coolant". Most people will probably be running motorcraft premium gold, or they flushed their system thoroughly and switched to a properly rated long life elc coolant.
