Oh yeah! Trust me... I popped for that expensive spring and stud at the Ford house. I left it installed, too! The Haynes manual DOESN'T tell you too remove it. Plus it ain't going anywhere! If it was it would have come off during the 6K miles I have put on the engine since I installed it!
I only pushed the tensioner tight with my fingers.
It's not like I torqued it over with a tool.
It isn't much further over than it was when I first installed it.
I just didn't torque down the bolt very hard when I put in the stuff last August and it slipped.
You can't leave it too loose or it will work it's way back like mine did!
In other words, it can't be loose enough to move or it will do what mine just did and get all floppy and noisy.
I know a source at a Ford dealership that will know.
I was holding off calling him (reserving those calls for importatt stuff.)
