Hey everyone,

So after 5 years of being a member here, I finally got my Z! It's a 07 6mt Enthusiast edition. The car is great, and it has 60k miles. I just hear a squeaking noise at idle and it seems to be coming from the belt area towards the front of the engine. But I know how easy it is for sounds to bounce around. I took this video with my phone hoping the squeak would get picked up, but I can barely hear it. Hopefully one of you can.



If you can't hear it, I'll give you some more info about the noise. It's not a constant tapping noise, but rather has some sort of timing pattern to it, about the time it takes the belt to make a revolution. Please don't flame for me for not searching - that's all I've been doing for a day. In fact, I came across this guy's thread which has an even better video of a similar sound:

In the event that you can hear the squeak in my video, can you tell me if its belt related or an engine related noise ---> REALLY hoping it's not the latter. I hear HR engines are really reliable.

EDIT: The squeak doesn't go away once the car is warmed up also - it's always there

Referring to the 2nd video, even to me it sounds safe to say that it's coming from the belt. The only thing is that I checked if my belt was loose and it seems pretty snug with hardly any play. I also doubt it was ever replaced. During my searching I hear mixed views on using belt dressing because some say its hard to clean the pulleys later on.

So please give me your insight. Thanks in advance!

It sounds like its something with the belt. I'd do just what the first guy said in the other video. Try tightening and loosening the belt(it can be to tight) if that doesn't work then take the belt off and spin the pullies to find out which is squeeking.

wow I'm surprised you even heard the noise in my video.

60k on the original belt is kind of overdue anyway right? As long as its not engine noise, I'm happy. Thanks for the reply!

I can't hear much in that, either but I don't hear the typical loose belt noise. I think that I might have heard a bit of a bad bearing in one of your tensioners. Do like the other guy said (loosen/tighten/etc.)

I thought we have self adjusting tensioners though?

Yes we do but it's just a spring loaded tensioner so the spring can wear out.

I'm definitely going to take a better video tomorrow, but this time further away from the engine so the squeak can be heard more clearly.

Hey guys, so here's an update:

Tried taking a better vid, but it couldn't pick up the noise. So I experimented and basically sprayed the belt with water and the noise went away. Then when it dried up it got louder and more constant. Definitely safe to say it's a belt issue then right?

The belt looks to be in really good shape too, from what I can see.
