1.8T wrong coolant T piece

[cumbriakevin]

I've checked the T piece on the coolant following recommendations on here to replace the plastic T with the metal one. On checking to make sure the metal one was not fitted I've become confused. Looking at the coolant drawing I'm imagining that 3 is the correct piece with the small stem coming off it. On mine there is no stem. Am I looking in the wrong place or right place but wrong T piece on there. it looks like the one for the non turbo but I'm not confident enough to know whether I'm just making an error in where I'm looking...
