And this issue is a curious one
After pretty much beating the internet because I've searched so much... all I have EVER found on squeaky pulleys and belts is that it supposedly happens when cold and then stops when hot.Except of course, if it's my car... because in my case it's exactly the opposite.
My G35 (2003) is quiet and buttery when first started both at low and high rpms, but once the engine gets up to any sort of normal operating temp (generally in 3 minutes) and a normal driving rpm (2000-3000 or higher) I start to get an INSANELY LOUD SCREAMING SCREECH/SQUEAL. I'm not sure I can properly convey just how loud this sound is with words - I mean, it's so loud you can hear it blocks away. It literally hurts my ears (bad) if I'm standing beside the car and someone revs the engine. Oh, to add to the confusion, as I'd just stated about once everything is all heated up and the sound is at it's worst... if I stop and let the engine go back down to idle speed there is almost no sound of this at all again! Just the random fairly quiet/light chirp of that sound. A harbinger if you will of the next press on the accelerator. As soon as torque/throttle is applied again - whoa baby does it get LOUD!
So again to note, the sound is tied in volume and *when* it happens to the RPM of the engine and apparently the temperature of the guilty component.
--------------
Cold Engine with any RPM: low sound to maybe not even the sound at all
Hot Engine with Low/idle RPM: low sound to maybe not even the sound at all
Hot Engine & High RPM: lots of loud squeaking.
After doing my best to get a feel for where it might be coming from by listening, it appears to be on the front passengers side area of the engine around that end's tensioner pulley or steering pump (That's the one farthest out on the passenger side right..the steering pump right?)
I'm not familiar enough with this car (only owned it for 3 days at this point) to know if I can take all the belts off and start the engine without destroying it. Can I do that? If so, I can start the engine and determine immediately if it's a pulley because if there are no belts and no sound then tada of course it is.
I've only driven the car a total 7 miles since I bought it trying to be err on the extremely safe side. It HAS to be fixed, and I'm trying my best to figure it out - so your input is MASSIVELY appreciated.
