yup i bought another 4th gen a few weeks back, some of you may rember my burgundy 5.5 gen.



But heres my prob with the 4thgen, i noticed the engine whines bad, and no theres no S/C....

It does sound like its coming from the pullies. what should i check? / replace??
belt tensioner? alti pulley ??

and sugestions would be cool ,thanks

 

check your alternator and also the AC compressor. I hit a bad puddle one day in mine, and the following day I had a whine that resembled the noise of a failing alternator. I narrowed it down to the AC compressor and i bypassed it for now with a shorter belt.

 

Probably the alternator. Use the screwdriver to the ear test and see if you can pin point the device making the wine.

Good luck with the car!

 

this may sound silly , but anything i can spray to maybe give it as a temp fix for a week or 2,
wd-40 or something ?

i just simply dont have the time to fix it but dont want anything to break...

 

I have a whine too lol what should i do? Deff check alternator man.

 

 

I have a belt driven intake tho.

 

If it's a high pitch squeal then it's likely the belt just needing to be tightened. If it's more of a metallic whine/hiss noise then it's the compressor. Not sure what model year yours is, but if it's a 97-99, I can give you the info where you can get a remanufactured one for $175+shipping. Great seller and it's $150-200 less than autozone or advanced remanufactured ones. I think I got the last 95-96 he had, but I can check with him to be sure if needed.

 

If it goes away when you turn on the AC then it's your AC clutch bearing. For a temp fix just get a ~920mm belt and bypass the AC (that's what I did).

 

it is clearly a whine type noise....
but it doesnt change when i turn the ac on or off....??
still the compressor?

tried spraying everything ith wd but it didnt help....

 

Does the whine sound like a faint s/c,If so It Is more likely the alternator and It's about to go out on you.
I forget which model (97-98) It was but If I choose It was a 98 with the alternator problems or recalls. I am sure this Is the symptom of a bad alternator and It's probally on it's last legs.

 

ya man does sound like a faint/crappy s/c.

and the car take a long second or two too start latly.......

 

It could also be the a/c idler pulley assembly, I have a whinning noise as well on my maxima and I just recieved my replacement idler pulley. I will be putting it on tomorrow I will let you know if that takes care of the whinning noise.

Good luck with the new car and enjoy.

 

Take a long pole and stick up against alternator see if you here the noise go through the pole. Then put it up against the compressor. My old car was making a whine from the alternator even though it was still working fine and it sounded like I had a S/C. I got it replaced just in case.

 

check the alternator, best way is to take off the belt start the car see if the noise is still present but i had that problem on my 96 and 99 max made whinning, hollowing n noise before it went on me. My brothers i30 has that problem now just have to change the alternator.

 

If the car Is pausing while your starting It,It can be that It needs a tune-up and It can be a bad grounding on the alternator and the starter check that first.

 

its not realy pausing , but it seems like its taking alot more cranks to start then it should .(and its not like its cold or anything anymore in CT...)

 

it was the alternator....

the noise got real bad, i removed the belt.

tensioner as good.
then i go to spin the alti pulley and was so hard to spin! ! it as siezed up bad !

new alit i gotta say was a pita to put in , i wish i had inspector gadget to help me out but I got it...

thanks bros !

 

glad you found the issue start small then work to bigger things thats how you trouble shoot. You can change the alternator yourself not that hard done it a few times.

 

Wow. I had this happen last night for the first time. Totally sounds like a faint supercharger too. Am glad I found this thread. I'll do the screwdriver to the ear listening method, but it sounds exactly the way maxspeed96CT described it.

Any suggestions on the best/cheapest alternator? Should I buy only Nissan parts for this, or is it a Kragen/Checker/Shucks special?

I had a bad experience with a Kragen alternator on an old Acura once.

 

Why look for the cheapest way out? If the stock one last over 100k why not get it from them?

 

My car has only 55k, and I am getting the whine

 

I just got this whine today. Was odd, I drove to the supermarket and it was running normal then I get out and go to drive home and the whine started as soon as I started it. Struck me a little odd that it didn't build up over time, it just happened.

I haven't had the chance to check and confirm it's the alternator, but it was my main suspect even before I looked at this thread. Mainly because my headlights don't seem as bright as they once were. I'll be popping the bonnet tomorrow and seeing what I can find...
