This type of SB tool isn't any help? It's what I use. Moving the power steering reservoir (without disconnecting the hoses) isn't hard.
@Wildcat, Is it like the Snap-On tool?
With a standard socket, that particular tool will not fit between the bolt and the frame. (Although I think you can remove a motor mount to get better access, but that involves a lot of work since this motor mount is attached in a few different places, and that also involves jacking under the oil pan with a section of wood to support the engine while the mount is removed.)
A low-profile socket would probably work on that particular tool, but even then the angle of a straight tensioner bar is not correct, and will not stay square on the tensioner bolt--the bar would need to angle towards the engine slightly to stay square. The Snap-On appears to has a compound angle on it, but it's hard to tell as it's from a drawing in the service manual.
This is an example of a Honda tensioner tool:

Note that it has a 12-point on one end wrench on one end to fit narrow spaces, and a welded-on socket to keep the other end low-profile.
In my case, I need to remove the bolt, then remove the tensioner pulley...so I get double the fun here!
