Squealing Belt on my 300?

[bahnie]

Hey, im a new comer here. I have a 90 300 zx, not a turbo. I have had the worst time with my fan belt squealing, we changed the alternator when i first got it, and since then its been nothing but trouble. I'm currently on water pump number 4, I have also taking it to a few autobody shops, but no one knows what is causing the belt to squeal, everything lines up and the altenator is apparently fine, it is even squealing when there is nothing on in the car (a/c, radio/subs, defrost, heat, lights) any ideas?

first of all you're in the wrong section, but to aoffer a bit of help, the car has 3 belts;alternator/waterpump, power steering, and a/cyou make it sound as though this is a constant problem? if so, simeply remove one belt at a time till the squeal stops, I'm not suggesting you try driving it with no alternator/waterpump belt or power steering but just to help find the problem with a basic fire up test, from my own experience the power steering belt is a huge pita to tighten, also if you have a coolant or other fuild leak leakign onto the belts then you need to fix the leak period! as for your fourth waterpump, I've had bad luck with aftermarket replacements pumps, the nissan units cost only a few bucks more and have a great track record
