Belt squeak on startup, any ideas?

Belt squeak on startup, any ideas?
Got a serious belt squeak when I crank it up. Revvs to about 2k and maintains for a couple seconds, then drops down and squeaks for about 30 secs. It goes away, but when I crank it the squealing is bad and I leave the house at 6a in the morning so I'd rather not put my sleeping neighbors through that. Anyone got ideas on what I could check? I figured it was a loose belt, but it seems to be tight enough. Could it be too tight?

Which belt are we talking about here?? If it's the A/C PS belt make sure the A/C unit itself is tight on the engine. I had a problem on my 91 where the belt kept coming loose. The problem ended up being the A/C compressor mounting bracket was coming loose from the engine. You can't see the bolts because they are behind the compressor itself. Loosen the belt and grab the compressor and make sure it doesn't move.
BTW, never run a new belt loose as it will slip and glaze and then you have a used belt that will always squeak.

Tighten the belt. Give the belt slip stuff from a local auto parts store a try. I did that and it doesn't slip anymore.

No offense but the first thing you need is a basic manual for the car.
I don't remember if you said what engine you have and I've had too many beers to care so anyway look at these

They will teach you all that basic **** you should figure out on your own but save you the time.

Not sure, this is my first MX-5, but I do know it gets worse whenever I raise the eyelids and as I understand they are controlled by vacuum.
Forgive my Mazda ignorance, but what's the best approach toward tightening the belts? I'm looking at it, and can't seem to decide whether jacking it up or taking the intake pipe off is a better move. So how have you guys done it? Be specific, never tightened a belt before

Tighten from the top by removing the intake pipe. The procedure from there will depend on whether it is the alt/wp belt or the ps/ac belt. If it's the AC belt, the adjustment is the PS pump. If it is the other belt, the adjustment is the alternator.

like I said, I'm definitely a noob, but I was under the impression that the eyelids were part of the vacuum system. Maybe that was on a different vehicle w/ pop-up headlights though.
I did fix the problem today though, after the belt split in half then snapped. It was the AC/PS belt and its on there now. No more squeals for me. For posterity's sake, if anyone is out there hearing their NA squeal (belt slip-type squeal) on startup for about 30secs, be sure and check your AC/PS belt!!!

So my alternator on the bottom left is missing a nut to the stud could that be my reason why my belt squeals when the car is cold or could my belts just be loose they feel tight to me but im not to sure idk if the bolt that goes on the alternator stud where the pulley is at is a reason my car squeals when engine is turned off for 20 minutes or more any help?

Mine was squealing from the alternator pulley. I figured the alternator was getting worn out since I had just put a new belt on and that didn't fix it. Put a new alternator on with the same belt and no more squeal. It was $160 for a reman and came with a core charge, meaning you get charged $20 or so more if you don't bring in the old one. I was approaching 130k miles on the original.
