Remove the center bolt and spring from the tensioner, then remove the tensioner body (you must remove the center bolt first or the spring will push the plunger out when you remove the body).
If the tensioner's plunger is out to the last two or three clicks on the pawl, the chain is too stretched out and needs replacement.
If there are more than a few clicks left on the pawl, the tensioner will still be able to properly tighten the chain... replacement at this point is up to you.
Your initial post stated that the chain was stretched out... how did you determine this?
