Hi, I'm in the process of replacing my power steering pump. I am to the point of loosening the 19mm tensioner "clamping bolt" but the thing won't budge. I'm using a half inch drive rachet with the 19mm socket so I do have some leverage. I have read so much here about tensioner problems, I don't want to screw it up. Should I use my 2 foot breaker bar and lean into it, or am I going to mess it up? I've had two tensioners replaced (by an experienced Mercedes mechanic) in the last three years so I don't want to pay for another one.

Reason: to add that previous 2 tensioners were not installed by me.
