4.2l stuck tensioner bolt

Hello has anyone figured out a way to remove a stuck 50mm tensioner bolt? My tensioner is frozen and won't move and the bolt holding it to the engine is also stuck! I'm afraid to force it for fear of snapping it. It has the torx head on it.
thanks

The tensioner assembly bolt is regular thread. The tensioner pully bolt is left hand thread.

Make sure you are going in the right direction.

When I replaced mine when I was getting a squeal eons of years ago (found out it was the 4th alternator into it), I replaced it. It was on there, and I used brute force to get it off. Felt like it was going to snap, but it didn't. It's actually a solid bolt. Don't know what grade it is, but it would take a LOT to break it.
