There is no metal tensioner pulley.
There is an Aluminum timing belt idler pulley though:
No clue on if the tensioner stays near the line or not ... can't check mine because it's a bit different setup.
I'd say if the belt feels taught and isn't walking to either edge then you should be fine.
Double check that the finger is in the timing plate though. Sometimes it pops out and you don't notice,,, black plate there's a slot for the finger of the tensioner to fit into.
