Idler pulleys and belt health
An idler pulley is a plain guide that keeps the drive belt on its path and at the right tension. Because it does not drive an accessory itself, its main wear points are the bearing and the running surface. A smooth pulley surface helps the belt track evenly, while a rough or glazed surface can wear the belt edges. Check the pulley at every belt inspection, looking for play, grinding or a shiny, polished surface.
When the belt is replaced, inspect the pulley and the tensioner together. A belt that has cracked, frayed or glazed can damage a sound pulley, and a new belt on a worn pulley will wear quickly. Keep the pulley clean and free of oil, and make sure the mounting bolt is tightened to the value in the engine service manual before the engine is run.
