Remove the belt, then remove the bolt holding in the idler pulley.
First you would need to take the serpentine belt off of the engine, and then remove the bolt in the center of the idler pulley. I have included an instructional vieo of how this is done.
The idler pulley on a 2003 Nissan Sentra 1.8 is changed by removing the engine accessories, removing the drive belts, and loosening the retaining bolt. The pulley can then be removed from the vehicle and a new one bolted into place.
Take the belt off, un-bolt the idler pulley, bolt the new pulley on, and finally put the belt back on and Viola!!
NO it is not.
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
The idler tensioner pulley on your 1999 Ford F3 50 pickup truck is held in place with a single retaining bolt. The retaining bolt will go through the middle of the pulley. Tighten the retaining bolt to install the tensioner pulley.
Belt tensioner? Idler pulley?
Should only be one bolt in the middle of the pulley that releases it.
from the bottom 13mm loosen idler pulley bolt then turn adjuster bolt under pulley
