start by cleaning the crud out of the socket. Try the T 45 again. I use one of those "gimme" shirt pocket screwdrivers to dig road grime out of them so the Torx will bottom out in the socket.

YES, really.
The spring in the tensioner isn't making noise. Actually the pulley bearing isn't either but I feel looseness. $14 vs. $45. It's a 76,000 mile truck. If it was 150,000 miles I would.

To me, it looks more like a Polydrive. If you look close you can see that the lobes are squared off and are not tapered like they are on a Torx Plus socket.
