08' Passat 2.0tsi coolant line route?
 

I have an 08' Passat 2.0 that had the tensioner failure. Long story on how I got to where my repair is today -I started the repair in 2015 -fast forward to Im finishing the repair now and Im having trouble finding the route and origin of some coolant lines. Specifically the ones that go to the rear if the cylinder head. I watched a youtube video and it seems that he says that 2 of the hoses come from the heater core, then the small diameter hose doesn't get addressed and gets covered by the air box in the video so I can't see where the origin of the hose is that plugs into it. I have looked everywhere for this info. I try not to lazily ask for things like this.
