I plumbed in one of those flush kits so I can flush the block as well. Motorcraft makes a good cleaner. Drain enough coolant to put a half bottle in the radiator then go for a twenty minute drive. Drain the coolant then fill with water and put in other half of the bottle in and go for another twenty minute drive. Drain and use the flush kit if you have it, if not then refill with fresh coolant and distilled water. Don't forget your DCA.
