Ahh ok good to know that, I just asked her, but she said she hadn't use the washers that morning. Reading online mentions under bonnet white smoke could be brake fluid or other hydraulic fluids ? Sent from my iPhone using Tapatalk

Hahaha yeh could be there is a lot of junk in there Sent from my iPhone using Tapatalk

Ahh ok fair enough....it's just odd because we have never seen it before, I'll tell her to keep an eye on it to see if it gets worse Sent from my iPhone using Tapatalk

Hey does anyone know what this could be? girlfriend sent me this video in the morning she only notices it in traffic, car is Ford Focus recently serviced. Temp and coolant level all normal. https://vimeo.com/170923365 https://vimeo.com/170923468 Sent from my iPhone using Tapatalk

Thanks again Mitz for sorting me out new belts under warranty, can confirm the belt change has worked a treat and no more squeal noise guess it was just a bad batch from gates then. The thread link for anyone that's interested / experience the same thing: http://www.350z-uk.com/topic/104861-alternator-or-battery/page__st__20

Hi Guys just an update to this as i have resolved it now. I went to check the belts but they were already tight, any more and they would probably snap. So my mechanic inspected for free and said the same thing, tension is correct not loose at all, slight shine on the alternator pulley but nothing to be concerned about. His conclusion is that the belts could be a bad batch and recommends changing the belts first. Major props to Mitz at Cougar store for getting new belts to me for free under warranty, had them changed and the squeal is now gone, even on cold start up's Happy days! Just hope it stays this way now.

Haha thanks all for the positive reviews currently placing an order with Ian as we speak ! Sent from my iPhone using Tapatalk

Ouch that doesn't sound pleasant! Will be changing them soon

Just discovered Ian's thread too...looks perfect and exactly what i'm after ill be in touch with him. Thank You!

As the title says

Looking for a guide on striping the boot trim panels (including central bar, side panels, and boot lid panel) as I plan on sound deadening it all soon. Found a couple useful resources so far: Removing Interior trim pieces: http://imgur.com/a/PdaLM Boot trim with pics: http://www.350z-uk.c...ix-boot-pop-up/ Boot Trim tips: http://my350z.com/fo...ng-purpose.html Any more guide links or advice? Many Thanks Darmo

Just bought myself 45 sheets of Silent Coat (for boot and doors), along with the rubber isolator (to go on top of the deadening sheets in the door) and memory foam sheets (to go inside tweeter housing and inner side of of plastic door trim). Feel pretty confident with the doors, however never taken the boot apart before so that will be all new to me. is there a guide somewhere for stripping the 350z boot apart?

So the Mechanic this morning said that he can't tension the belts up any more because they are already tight, any more could result in a snap, he demonstrated to me and I agree. He checked the pulleys and they all seem fine, some slight shine on the alternator pulley which could be a sign of it slipping on this pulley but nothing to be overly concerned of. His recommendation was to change the belts first.

Hey Scott, ahh sorry to hear you had to go through that glad it's all sorted now My belt tensioning is tmr morning now and I'm hopeful that will be the final fix because the last few starts the squeal has not been as bad (like 3 seconds), makes me think it could be weather / temp related. Anyway, just in case it turns out to be Alternator for me also I might be back in touch to see where you bought yours from lol.

Or that! haha. Glad you found the source

Thanks All, The garage who did my service and replaced the belts back in September is going to tension them up for me for free on Monday

Ah thats the one Thanks for providing, ill try and give this a go.

Seconding this. Ultimately it sounds like your belts are too loose either because they've stretched or are the wrong size. Retension or fit new ones. Thanks both, the belts are gates from Cougar store, so i'm sure they are right, perhaps they have just stretched over time, I remember seeing a guide to tensioning the belts that doesn't require taking the car of the ground (if you have skinny arms) but for the life of me can't find it now.

Same, although mines worse and i can't live with it: see my video here: http://www.350z-uk.com/topic/104861-alternator-or-battery/page__st__20

Hi Chris. did you ever manage to get to the bottom of this?

I can hear it in your video and my first impression upon hearing it is Belt Squeal. I'm having loud long squeal at startup and your noise sounds exactly like that but just for a short second. The fact that it's directly related to a specific RPM range helps narrow the focus of diagnosis, a quick Google search of 'belt squeal 2k rpm' or 'belt squeal above 2k rpm' gives many forum posts you can read, one of them (RX7 forum) points to a particular pulley. Other than that, and this is just me thinking out loud, could be a whistle that's created from your tyhpoon sucking air in at that RPM range. So then i Goggled 'K&N typhoon squeal' which led to me to this post which is exactly what you are experiencing: http://www.yourcobalt.com/forums/chevy-cobalt-owners-lounge/11943-k-n-high-pitch-squeal.html No problem can't be diagnosed with a little googling

For over a month now, I'm getting loud constant squeal from the belt which lasts 6-8 seconds immediately after I start the engine. I notice the belt squeal stops as soon as the volt reading reaches around 14v (which can take 6-8 seconds on a cold start) The Squeal happens on non cold starts too if left for more than 15 mins, although it's a not as bad / long then. I have replaced the Battery with a brand new Optima Red top. The engine cranks into life instantly now, but the Squeal issue described above is still the same. So this leads me to think it could be Alternator? or something else (loose belt). The belts were changed with brand new gates belts back in September 2015. FYI in May 2015 i installed a new car audio system running a total of 900w RMS. Any insight or advice you can give is much appreciated. Ill add a video to demonstrate https://vimeo.com/166207333
