On my 97 3.5L you have to loosen the bolt (15mm)on the front of the idler (loosen, don't remove) then go underneath and the is a 13mm bolt that adjusts the position of the idler for tension. Loosen this and the idler should loosen up.
A simple gear train with idler is a gear train the contains 3 gears. These gears are called the driver, idler, and driven or follower. The idler merely changes the direction of the follower so that it is the same as the driver.

Most technicians refer to the idler pully for the timing belt as just idler.
Need to know if you have a Detroit, Cat, or Cummins engine in order to answer this. As for the idler pulley itself, it's pretty simple to locate - it's the pulley which only spins, and doesn't actuate a pump, alternator, compressor, etc. Removing it is as simple as loosening the belt, unbolting it, and installing it in the opposite order.
Are you talking about the "idler pulley"? They are quite simple to change. Loosen the serpentine belt by using a socket on the center of the tensioner pulley, slide the belt off the idler pulley, use a socket to pull the center bolt of the idler pulley and replace the pulley with a new one.
