2010 nissan sentra weird engine noise..

[johnshop]

So we have this car since it was new, and we have always taken care of it. Oil changes every 3k and we did the timing belt job noted in the manual at the dealership, so it has been properly taken care of, and never abused. Anyhow, the car has 65.XXX miles and surprise surprise... The car comes out with this noise right after the warranty runs out.... Great.

So here is a video of the engine, and it just doesn't sound right to me. There are no lights or anything and the car runs fine. Another thing that happens is that when you turn the ac while the car is idling it shakes for a second or 2 because the revs drop for a sec, The car never really did that before.

So here is the video, hopefully you guys can enlight me and give me an idea of what could be making the engine sound like this:

Are you sure the 2010 has a timing belt? I thought it had a chain and it does sound like the guides or tensioner is loose? How long ago did they mess with the "timing belt"???

thing is that i have not mess with anything, it has always been dealer serviced, the only car i ever messed with was my 300zx, because you know... they break all the time

and as far as i know they changed the belt that is on the passenger side, is clearly visible, it might not be the timing belt, but it's a belt.

Then mostly likely it's the accessory belt. Have the tensioner or pulleys checked out.

Hey All,
My 2008 Nissan Sentra is not starting. Battery checked out good, which I assume the alternator is good also, otherwise, it would not have charged the battery. The starter seems good also as it "clicks", but fails to start when I turn on the ignition. Any and all suggestions are most welcomed. Thanks.

johnshop,

Were you ever able to resolve this issue? My 2008 Nissan Sentra makes the same noise and has the same issues with rough idling and the revs dropping significantly when the A/C compressor kicks on.

I recently had my A/C compressor replaced, so my attention is on the tensioner and alternator, although the alternator passes a load test.

EDIT: He hasn't logged in since May of this year, and I can't send private messages since I just registered. Can anyone send him a private message to check the thread?
