Remove the belt, then remove the bolt holding in the idler pulley.
Take the belt off, un-bolt the idler pulley, bolt the new pulley on, and finally put the belt back on and Viola!!
On the belt routing diagram under the hood (near the grille, but under the hood) you will find the location of the 'tensioner' pulley. You need to get a 15mm socket and place it on the bolt on the tensioner pulley. Then use a ratchet to put clockwise pressure on the bolt to loosen the tension on the belt. This will allow you to remove the belt from the idler pulley, remove the bolt, put on the new pulley. Now put clockwise pressure on the tensioner pulley again to put slack in the belt so you can slip it around the new idler pulley. You're done.
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on

NO it is not.
The idler tensioner pulley on your 1999 Ford F3 50 pickup truck is held in place with a single retaining bolt. The retaining bolt will go through the middle of the pulley. Tighten the retaining bolt to install the tensioner pulley.
Belt tensioner? Idler pulley?
from the bottom 13mm loosen idler pulley bolt then turn adjuster bolt under pulley
Should only be one bolt in the middle of the pulley that releases it.
13 mm
Adjustment is on the idler pulley with the tensioner bolt sitting right below the alternator. I also had to loosen the center bolt on the idler pulley before it would move.
