Idler may be held by two bolts - one to pivot it and one to hold the tension while you tighten the pivot.

I only see the bolt holding the pulley and have tried to put a wrench on the pully to lift or release the tention but it doesnot budge.

There should be a belt tensioner, usually by itself. Put your wrench on it and either push or pull. Some have a bolt on top which you unscrew to loosen the tensioner.

Is there a diagram on the underside of the hood with it's location?

Should look like this:

Tks. Irelaced the serpentine belt but it won't stay on could it be the waterpump pulley as it looks like it is loose and the tracking comes of of this pulley first.

If the water pump pully is loose and not running true, sounds like a bad bearing in the pump or the pully isn't tight. Did you retighten all the bolts when replacing the belt. Double check all bolts.
