I just started hearing a noise in the engine bay over the past 2 weeks. It has been progressively getting louder. The sound started off really low to where you could only hear t with the windows down, but now, I can hear it with the windows up. If I put the windows down then it is really loud. I check my SC belt and it doesn't sem to have any unusual wear to it. The sound comes in around 1800rpm's and continue until the whine of the SC drowns it out. If I don't put the car under WOT I can hear it all the way up to 3500rpm. Whatever it is, it gets louder and faster the higher the RPM's go. I recenly took it to GRD (as many of you may know that Stillen sent me a bad SS box and GRD was putting in a new one) to have a dyno pull and my A/F ratios were great with no sounds of detination whatsoever. I am just wondering if one of my pulleys or belt tensioners are going out.

Say this outloud... ee ee ee ee ee to maybe a chirping sound? Arggghhhh!!!! This is so frustrating!!!!

My wife says that it sounds like a clicking sound, but who knows.

I really don't want to have to take it to GRD again (they are about 2 hours away). I did notice 2 things when looking at the belts.

1. The belt to the far left looks a little frayed on the top back edge

2. The belt tensioner for the upfront center belt I can wobble it with my finger.

Neither of these 2 things are associated with each other as far as I can tell.

Any ideas???? for getting this fixed??? Would a standard belt shop be able to possibly fix this or would I really be better off to go back to GRD (4 hour round trip) for them to diagnois this?

Has anyone expierenced any of the pulley's or belt tensioners going out on these setup???


Any suggestions or other experiences would be helpful.

 

first belt you described is the p/s belt if its frayed it will squeal.ive had to retighten this belt a few times.is it louder when 1st started,or is it the same all the time.the tensioner will wobble a teenie bit but not much more than that.and if the belt is frayed its going bad and any shop can replace it,just find your instructions and give them the belt #.make sure to tell the shop to tighten it a little tighter then what they think is tight.

 

I can't really describe the noise, but it doesn't start until 1800 rpm's. The car doesn't make any noise at start up. And when I say frayed, I notice a couple of threads broken on the back edge of the belt.

 

we are hopping back and forth from the 2 forums but,with the belt fraying get it replaced.im willing to bet thats the problem.also which tensioner has the free play and how much.

 

We will continue this over at my350z.
