Wiggling and maybe a shot of penetrating oil are you friends in pulling this off.
As for a procedure.
Disconnect neg cable at battery
Take a look at picture for bolt location, remove the bolts (don't forget the back one that can be seen in the picture)
If you have the metal elbow as part of the tensioner, use the O-ring off the big end of the unused coolant elbow as the new o-ring. It'* the right size. then lube all the o-rings and slide the assembly back together.
Start to tighten down and wiggle the elbows in the bores to ensure they seat nicely w/o pressure on them.
