Does it only do it when you first start it up? Is the ac on or off? Does it go away after the car has been running for a minute?

When is the last time you changed your belts? Also have you checked to see how much tension there is on the belts that are on the car right now? You may just need to adjust them but if you haven't changed them in a while I would go ahead and just replace both of them since you're already going to be messing with it. They don't cost too much.

Either the serpentine belt is loose (belt connected to your alternator), or it's on it's death bed. To tighten it, there's a bolt under the alternator. You'll need a 1/2 wrench to loosen it, then there's 2 bolts right infront of the alternator (10mm). The one on the left is to hold the bracket to the alternator. The one on the right is to loosen or tighten. Tighten it a bit, then tighten the bolt under the alternator, and try it. The belt should feel pretty tight, unlike the chain on a bicycle where you want some slack. But you don't want it too tight. If it still squeals after you tighten it and stuff, it's time for a new belt. (Just had to tighten mine Friday 'cause it was squealing). The shop never put the main bolt ontop of the alternator back in when they replaced my crank pulley?

have you checked your fluids??just a thought

It's there a possbile way to add dw-40 on the rollers of the belts??? Sorry for being a noob. LOL

WD-40 could be used as a temporary fix. I see this problem all the time when people replace their drive belts with cheap pieces of crap. Check the condition and tension of the belts.

If it didn't have any power steering fluid in it, it would only whine while making turns. Mine did this for about a year, until when I had it in the shop, they fixed it for me. Said it wasn't even hooked up right.

DO NOT spay wd40 on your belts or belt pulleys.

the reason for the squeaking noise is they are slipping.

just tighten the belt a little and it should go away. The belt has stretched from age and has gotten too loose *or* somehow something slippery got on it.

don't go crazy tightening it, just do it a tiny bit then test and see if the squeak goes away. If you overtighten it is bad for the alternator pulley because it pulls on it too hard.

Do not use dressing either, just adjust the tension.

Edit: in his eternal wisdom my father just told me that sometimes the nap on the inside of the belt gets worn down and smooth, thus causing the slipping and squeaking. In this case, if the belt is tensioned properly but the belt is slipping because the nap on the inside is worn, adding belt dressing to the belt is actually a clever fix instead of being the ignorant neanderthal solution I always thought it was.

not the OP but when i start up my cb7 its only like a squeeek then its over
it seems to do it right after the engine starts
but as soon as the engine returns to the normal idle it stops

again, most likely a slipping belt. when engine goes from standstill to 1200 rpms when you start it, it causes the belts to slip because they can't catch up right away. Then often the noise will stop once the belt speed catches up with the pulley speed.

that's probably not the only thing it could be, but it's the most likely one.

i figured it was a belt i will check it out in the morning

thanks batever

Those belt adjusting brackets are tricky to figure out, extremely non intuitive. Write back if you want help. You have top loosen the big pivot bolt first, then loosen the adjusting nut underneath the pump or alternator (on an axis perpendicular to the bumper) *then* turn the adjusting nut that faces the front of the car counterclockwise to tighten or clockwise to loosen, then snug up the first two bolts to secure everything in position.

Bolt head sizes are 14 or 15 mm (depending on alternator or power steering pump, I bet the squeal is from the alternator though) and 12mm and 10mm for the other two smaller fasteners. If you're doing the power steering pump the big pivot bolt can be gotten with a 14mm combination wrench using the closed end on the bolt and and hook a 15mm closed end wrench into the open side of the 14mm wrench to make a longer lever arm. Otherwise you have to take the power steering pump tube off and I don't recommend it as it will drip hydraulic fluid all over the place, the last thing you want on your pulleys, belts, and alternator windings.

I would post a photo of the wrench thing but I don't know how.


Good luck!
