big66440 Posted November 9, 2011 Share Posted November 9, 2011 can renix jeeps be upgraded to the newer automatic serpentine belt tensioner's? Quote Link to comment Share on other sites More sharing options...
carnuck Posted November 9, 2011 Share Posted November 9, 2011 I wouldn't. Manual is far superior and doesn't wear out as fast. Quote Link to comment Share on other sites More sharing options...
flint54 Posted November 9, 2011 Share Posted November 9, 2011 Well, I will, respectfully, offer a different view. I would switch to an automatic belt tensioner in a heartbeat if I could find that this has been done before (I have not yet found it having been done, even though have asked around here and elsewhere). I have had many vehicles with this spring-loaded device, and yes, they do fail sometimes, but I've never had one fail in less than 70k-80k miles, and they're cheap and easy to replace. A worrier would do well to carry a spare. Tensioning the belt by adjusting (beneath) the PSP is a royal pain in the a$$ comparatively. two cents...

87Warrior Posted November 9, 2011 Share Posted November 9, 2011 I too am interested in this. The tensioner in my TJ is still holding up at 110k miles. The problem, I don't think any XJ came with the auto tensioner. Quote Link to comment Share on other sites More sharing options...
