Well, just got done installing an OEM alternator in the Max. Actually wasn't all that hard. Anyway, after the install, I've got some new noises. Ther seems to be a whistling noise coming from somewhere around the alternator. This noise builds consistant with the rpms. I'm also getting a "poof" sound coming from the idler pulley that is consistant with rpms as well.
I can't here these noises while driving, but during idle at stop lights and from outside the car, I can really here it. Any ideas? Thanks in advance.

 

I just replaced my alternator as well, and I just realized I got a leak of coolant somewhere. I really hope it's not my rad and with 80,000km I really don't know what to think. I'm assuming the noise you're hearing is the belt that goes on the alt check with a mechanic and check on it. you may need to replace the belt. as for the poof sound, any more detail?

Also a bit off topic but how did you manage to post a thread? I've tried to post threads, and I keep getting the message

The belt is new so I know thats not an issue.
I also noticed that in the process of the old alt going bad and installing the new one, I lost a couple dash lights. One on the cluster, one on the radio and two A/C buttons. Somtimes I wish I wasn't OCD....thats going to drive me nuts.

Hmm, more specific on the poof sound? Well, sounds sort of like two popsicle sticks tapping against each other.

 

I just had a similar problem with mine. Just replaced mine about 2 weeks ago. Check the Alternator tensioner. make sure that your belt is on there tight. the tensioner is located right by the alternator.

here is a link to my thread with a picture towards the bottom of what im speaking out. http://forums.maxima.org/5th-generat...ine-noise.html

once i tightend mine, the noise went right away. also, make sure your hoses that you moved out of the way to get the alternator down are secure and tight. i rechecked mine when i removed mine just to make sure.

 

check the Belt tensioner... that's where your problem is
