I have a 92 XE pathfinder and every time I start it up, especially in the morning, there is a loud squeal coming from the front of the engine. It goes away after a few seconds but sometimes it lasts up to 10 seconds. Its also noticeable when the rpms reach higher than 2500 and goes away when I shift into anther gear, then it'll sound again when reaching beyond 2500 rpm. I think its coming from one of the pulleys but I don't want to spend $$ on something I don't need so I want to be sure. Does this sound like the alternator? Power steering? I don't have AC so the belts to it aren't hooked up. Any suggestion will be appreciated. I've added a video where you can hear what Im talking about. Thanks.

I had this same issue. Loud squeeling on start up, it would last for a few secounds then subside. This issue turned out to be the alternator. I bought a new alt. from a wreck and was good to go. Not the easiest install but have fun.

sometines its just the alternator pulley or belt

Have you checked the belt tension? It might not be any of the components (power steering, alternator, etc) but just a loose belt.

Not sure what the belt deflection should be on a '92, but try tightening it up a bit and see if it makes a difference.

check the belts, prolly one is loose somewhere

This used to be a problem on my 00 pathfinder. I had the fan belts re-adjusted and that fixed the problem. It still does it every once in a while, but that's a lot better than it happening every start-up.
