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.
no there is not.
It is the small pulley with a nut in the middle on the pulley assembly!
Check the alternator if that don't do it change the battery
Remove the alternator belt by loosening the tensioner pulley. Remove the wiring from the alternator. Remove the retaining bolts to the alternator. Reverse the process to install the new alternator.
It is built in to the alternator.

triple diodes in alternator are bad
how do you change the alternator on a chevy 2006 hhr
Defective voltage regulator. It may be built into the alternator.
Also in order to loosen the serpentine belt you have to use a wrench or something and turn on the bottom pulley....easy remove the serpentine belt for the fan area and remove the two bolts that hold the alternator down and unclip the wiring harness
The alternator should be on the front of the motor with a belt on the pulley and wires connected to the back of it that can be removed.
probably a TH700, but take a look underneath
