2004 D''ville - where to add Barts Stopleak

Hi folks,
 
Just had coolant flushed and replenished. Picked up some Bart''s stop leak tablets. Directions say to add at radiator cap but my D''ville doesn''t have one.
 
Can I add them at the over flow container or do I have to add by removing top radiator hose - making a mess...
 
what is your experience?
 
thanks for your advise

They are usually added to the lower radiator hose, not the upper. Never to the holding tank!
