A&Q about 350Z
Q:
This only happens sometimes.
For some unknown reason, my car is making a belt squeal type noise @ idle. It has only happened 4 times since I've owned the car. The sound comes and goes. What I mean, is that I will have the sound one day. And then, not hear the sound for another few months.
I have no idea what is causing it. But at idle, the squeal of the pulley is loud and irritating. I've tried two Nissan dealerships, but of course it wasnt making the noise when I brought it in. One dealership said the VQ has self adjust pulleys so there is nothing they can do????
Tonight it made the noise again (been a while since it made it) after I got on her a bit. Any suggestions? The car is running strong and has never been faster....
A:
Check the air conditioner belt for proper tightness. There was a TSB on the compressor and bracket on early 03 models. But, that noise was a clack not a squeak.
A:
Their are no "self adjust pulleys" on the Z. If it happens when your AC is on then its the Ac belt. If it happens without the AC then it is your main crank belt. Their is an adjustment for each and your dealer should fix it. If they don't and you are somewhat mechanically inclined, then you need a few open ends and a racthet to adjust it.
