1992 400E Serpentine Belt Tensioner Installation Procedure?

[400E_FAN]

I was looking for some help on how to set the appropriate tension with this poly v-belt tensioner. I searched the forum and found a few posts that touch on this but do not get into the detail. Detail in the CD-ROM is sketchy from my perspective....To be extremely precise I am trying to figure out how to set the tension marker? Can anyone who has done this in the past illuminate; step by step would be great....?

My car has the "old" style belt tensioner i.e the overengineered type with a tensioning bolt and a separate tension adjustment rod that goes through a hole in a bracket on the Power Steering Pump reservoir assembly.


Thanks
