Hard to tell if this question is to:
Loosen the central nut of the belt tension pulley. Loosen the tightening bolt. Remove the belt, install a new one. Set proper tension. Tighten the central nut.

The serpentine belt on a 2003 Toyota Rav4 can be loosened by turning the retaining bolt on the idler pulley. The belt can then be shifted inward to loosen.
All you do is look for the tension pulley and tighten it, see below
Easy. Use a 14mm socket to loosen the bolt which goes thru the tensioner pulley. This allows you to adjust the tension. The bolt which adjusts the tension has its head pointing at the ground and if you look up from under the van, just to the right of the oil filter (presuming you are facing the front of the van) you'll see that bolt head behind the tensioner pulley. Again use a 14mm socket (on an extension bar) and turn ccw to loosen and cw to tighten.
You are not suppose to tighten a timing belt. Only when you install a new one does that get done. When you are replacing it you have to loosen up the tensioner pulley assembly and it self adjusts under spring tension. Good luck
When looking form the passenger side of the car the tension pulley is on the right hand side. It is the one located in the middle of the "column" (second one down slightly indented to the left)
We recently replaced the serpentine belt on our 2003 Chevrolet Tracker. We were able to place a wrench (I believe it was 9/16") on the tensioner pulley and apply pressure so the pulley released tension on the belt. This however did no allow enough slack to install the new belt so we removed the idler pulley at the top center of the engine. With the idler pulley removed we were able to route the belt and with the tension released on the tensioner pulley, routed the belt under the idler pulley and reinstalled the idler pulley, then released the tensioner pulley and the belt was installed. Be sure to note the exact route of the old belt before removal so the new belt follows the same path. Hope this helps.
To change the serpentine belt on a 2003 Pontiac Bonneville, loosen the tensioner pulley and remove the old belt. The tensioner pulley is the wheel in the belt system that has a bolt through the middle in a slot that can be adjusted. Put the new belt on and tighten up the pulley.
As you face the car with the hood open, look on your left below the water pump towards the big middle pulley.
