Hi everyone I'm new to the forum unfortunately out of necessity because I have a 6 gen maxima. When I first turn it on there is a screeching/whistling noise coming from the belt area, as it warms up the noise starts fading away. But the noise is starting to be more consistent. Any help or links to "threads will greatly be appreciated. and thanks for having me here

 

Welcome to Maxoma.org!

It could be the belt. It could be loose or it is becoming hard and cracking or both.

First start by checking the belt tension. Press on the belt with a 20 pound force in the section between the alternator and the a.c compressor. It should only deflect less than .2 inch. Also inspect the belt. One the inside surface that touches the pulleys, if it has lots of cracks, it should be replaced.

See page 12 in the service manual. Link below.
