jlchomistek Posted January 18, 2014 Share Posted January 18, 2014 I am having a consistent squeal in the belt area at idle and increases with the rpms. I also have a rattle with rapid acceleration. The serpentine belt, tensioner, and fan clutch has all been replaced. I'm inclined to believe they are related. Any help is appreciated, I am a mechanic by trade and can do most work on my own. 2006 Pathfinder LE 4.0.

Slartibartfast Posted January 18, 2014 Share Posted January 18, 2014 The early VQ40s apparently had timing chain tensioner issues. Does it sound anything like this? 1 Link to comment Share on other sites More sharing options...
jlchomistek Posted January 18, 2014 Author Share Posted January 18, 2014 Yes , that's it. I have heard about the chain problem is that something I might be able to do ? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
jlchomistek Posted January 18, 2014 Author Share Posted January 18, 2014 Another question if I were to leave that be for a few more weeks with minimal driving will it cause more of a problem or be okay until I can get to it?

jlchomistek Posted January 18, 2014 Author Share Posted January 18, 2014 On second thought, I have a power train warranty it might be covered I will have to check that. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Slartibartfast Posted January 19, 2014 Share Posted January 19, 2014 Hopefully it's covered! There aren't a lot of R51 owners on here to give advice. You'll probably get more/better advice on Nicoclub or other forums with more late-model Nissan trucks. You might find discussions of warranty repair as well.

jlchomistek Posted January 21, 2014 Author Share Posted January 21, 2014 Thanks for the help. It is covered under my warranty. Now it is just a matter of positively confirming the issue. 2006 Nissan Pathfinder LE 4.0 4x4 Link to comment Share on other sites More sharing options...
