Here is a foto of what needs to be removed to get at the tensioner.
Fan shroud
Fan clutch
Serpentine belt
Fan clutch pulley
Power steering pulley
Water pump pulley
Remove 19mm bolt from tensioner
Remove Y shaped bracket.
Loosen power steering pump



Note that the fan pulley has 4 bolts in it.
The power steering and water pump pulleys are the same and are held on by three bolts.
Its better to leave the serpentine belt on and tight to be able to loosen the bolts in the pulleys easier.
Its easier to remove the fan attached to the fan clutch if you have difficulty with the bolts holding the fan
to the clutch.

Make sure you have the right tools for the job. Get a set of allen keys

Here is some more info on the tensioner. You can see from the fotos that you need to remove the water pump pulley to get at the 19mm bolt



To remove the Y bracket the fan and power steering pulleys must be removed. Don't forget you need to remove the tensioner shocker also.



Here is a foto of the tensioner removed. See that bolt at the bottom of the water pump? Very hard to get to with the tensioner in the way.



I can get to this stage from start in about 45 minutes.
