Northstar Posted November 21, 2004 Report Share Posted November 21, 2004 My Serpentine belt tensioner is chattering at idle and about 4,000 rpm on up. How hard is it to change it out or can I just change the pulley on it? Link to comment Share on other sites More sharing options...
Ben Posted November 21, 2004 Report Share Posted November 21, 2004 It is very easy to change. One bolt and that is it. Part is about $70 I think for the whole unit. Pully you can buy seperate for about $10, but the acutal tensioner was the noise with mine. Good luck with the repair. Link to comment Share on other sites More sharing options...

The arm was half seized on the pivot. There is also a stationary idler pulley besides the tensioner pulley. Last month the stationary pulley failed. You might want to check that while your in the area. It was only about $ 25.00 from the dealer.

acklac7 Posted November 21, 2004 Report Share Posted November 21, 2004 I believe the bolt goes through the center of the belt tensioner and into the engine block. I can't really see mine...It is in the center of the tensioner. Stick the correct socket in the hole (in the middle of the tensioner) and you will feel it. A.J.
