It's on the center of the idler pulley
First you need a breaker bar and 19mm socket to fit the "tension bolt". Turn tension bolt clockwise to release tension in order to remove the serpentine belt.
Loosen bolt in tension pulley, then loosen tension bolt. Replace belt. Tighten tension bolt. Last, tighten bolt through pulley.
no the bolt on the pulley does not need to be loosen just put ur wrench or rachet on the bolt head and turn either way till the pulley moves
Regardless of what type of vehicle you have, it is extremely difficult to replace a serpentine belt w/o a serpentine un-tension-er tool. This is a thin, long handle with a socket on the end that sticks out at 90 degrees of the handle. The socket slips onto the bolt-head of the tension-er pulley. Once the serpentine belt is threaded around all the other pulleys you put the un-tension-er tool on the tension-er pulley bolt and pull (or push) to achieve slack in the serpentine belt and slip it on the tension-er pulley.
no adjusting bolt u have a serpentine belt.that has a tension pulley that automatically adjusts if belt is loose, u need to replace belt
It probably has a tension release pully, not a bolt. The pully has no function except tension. Your repair manual probably has instructions on changing the belt and a photo of the small pulley. Mary

You pry it over enough to remove the belt. You loosen the tensioner pulley bolt and thread the adjuster bolt backwards on a 4.0L.
put a wrench on it as to tighten the bolt. That will release the tension. You can also push down on it but that will require a second person to remove the serpentine belt.
The tension on a 1988 Ford F150 can be loosened by adjusting the belt tensioner. The retaining bolt is loosened, the tensioner shifted slightly, and tightened down.
To release the 1990 Cavalier serpentine tension, use a socket and a ratchet. Put the socket on the bolt heat in the middle of the pulley wheel, and pull to one side, and the belt will be loosened to be able to be removed.
