You don't tighten it. It has an idler pulley that keeps the proper tension. If this is an old belt and is loose, then it needs replacing. If you have installed a new belt and it is loose, then either you installed the wrong belt or the idler spring is weak and the idler needs replacing.
Check your belts for tightness or glazed edges. If the belts are loose, tighten them. If the edges are glazed, either break the glaze with a piece of scotch brite or replace the belts if they are worn.
usually serpentine belts get their tension(tightness) from the belt tensioner
The Alternator and Power Steering Units have a tensioner bolt on each. The final tensioner bolt is just above the tensioner pulley in the top center.
From the front remove the brush cover on the bottom of the truck. You will find the two tensioners for the two belts. You will have to loosen the center nut(i think it is a 14mm). once loosened there is a 12mm bolt, loosen that and the tensioner will open. remove the belts and replace with new ones. Be sure to write down the routing, draw a sketch, or a take a picture. Reverse order to tighten.
if belt needs tightening, u need a new belt serpentine belts use a tension pulley that automatically keeps belt tight until belt is worn out or stretched.
Specifically, where and what do I do to tension either belt? Thanks!
if a serpentine belt is loose, it needs replacing. there is an automatic tension pulley on all serpentine belts. so just buy a new belt and install
The 2001 Honda Civic is not equipped with a serpentine belt, but has 2 v-belts. These are tensioned through use of a tensioner.
Gates ( they make timing belts etc. ) lists a 3.3 L - V6 engine for the 2000 Nissan Pathfinder and it shows as an interference engine
Loosen the belts, unbolt the old alternator, bolt the new one on, tighten the belts back up.
You don't. Serpentine belts are adjusted by a spring loaded device called a belt tensioner. If you belt is loose, then the tensioner is broken.
