CAT EC-1 ELC is probably the most recommended coolant. The next is maybe Zerex EC-1.

You'll want to do a serious flush before putting either of these in as they are not compatible with the Ford Gold and could cause issues.

Use Restore or Restore Plus to flush it.

Zerex ZXG051 Antifreeze,g05,1 Gal,yellow 4npn9
