Undo the top and bottom rad hoses from where then meet the cylinder head.  Put a hose pipe in the one that goes to the bottom and run the hose for a few minutes to reverse flush the rad.  Refit hoses, refill with cold water plus some radiator cleaner from motor factors / halfords.  Follow instructions on flushing stuff, then drain, refill clean water, run for a few mins, repeat 2 or 3 times with clean water to remove all flushing agent, then refill with correct antifreeze mix, will probably need 3 litres antifreeze.
