Can't get tensioner off broken bolt...N52

I've been trying to take the tensioner out for the past hour now. The bolt was already broken off. The tensioner slides out about an inch but won't come completely out. This seems like a common issue. Anyone have any tips on getting the tensioner out? This is exactly what I am dealing with right now:

Ah that's frustrating! I have seen this happen before! The problem is, there's not much space to use broken screw/bolt extractor. I dread the day I need to replace the pre-tensioner on my car! I am sure there have been a few members here posting about this same thing happening to them - hopefully they will have posted some handy tips to get this sorted out that will help!

I ended up taking a 7mm or 8mm socket with an extension, put pressure on the bolt and spun it counterclockwise. Of course this was after spending a few hours messing with it but when I saw it coming out slowly, I was so relieved.

Only about half the belt was on the pulley. Only a matter of time before it would completely slip and leave me stranded. I'd definitely recommend replacing the tensioner preemptively.
