The pulley may be fine, but the tensioner spring gives up. Replace the tensioner. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
Ranger Posted September 28, 2010 Report Share Posted September 28, 2010 If you got the pulley from Autozone it probably failed. I bought one of their Neverlast pulleys for my wife's car and it lasted 3 months. Link to comment Share on other sites More sharing options...
joeb Posted September 28, 2010 Author Report Share Posted September 28, 2010 i have read that the cheap tensioners have an internal spring but no dampener so they do not work like the factory units? the idler pulley just sings with the scope. just a whrrr sound. the tensioner body really clicks/snaps but it is erratic. i can touch the bolt head for the idler with the scope but the tensioner pulley is behind the arm so i can't really reach it.

blk987 Posted September 30, 2010 Report Share Posted September 30, 2010 changed tensioner. got an ac/delco and it is quiet. no more clicking/snapping. Are those tensioners inexpensive if you dont mind me asking, I will be changing mine along with the belt before the year is over. Link to comment Share on other sites More sharing options...
