Squeaking belt(?) when wet

It's been rainy around here recently, and every time it rains or gets humid, my drive belt (I'm pretty sure) squeaks at low RPM's (under ~1200) on my '01 HA v6.

Is there a good way to keep the belt from making so much noise?

It's usually fine after driving for a while on dry roads, but when it's wet it gets quite annoying.

Thanks!
 
You can try belt dressing (spray from any autoparts store) or replace the belt. It's probably loosening up.
 
You can try the belt dressing which is a quick fix and will work for a little while, but you really need new belts. I would just replace the belts now.

Yes, the first thing he should do is check the tension. A belt may stretch a little bit but still be ok. If the tension is fine and it's still squealing it's time to replace the belt.

The problem is at the contact points between the belt(s) and the pulleys. Over time the inside of the pulleys can become smooth or "polished" by the continuous contact with the belt. If re-tensioning th ebelt does not help consider replacing the belts. I fthay does not work then consider replacing the pulleys as well.

Good luck ...
 
How do I tell if the belt is "tight enough?"

I"ll check the pulley conditions and see if they are polished.

Thanks!
 
There is a deflection method to test the tension of the belts. You push on the belt between two of the pulleys with a certain amount of force and see how far the belt will move. I forget the specifics but I don't think you want it to deflect by more than half an inch.
By HA I'm assuming you mean Honda Accord? The older Honda's did have adjustable tension on the belts. Usually a pair of bolts on one of the accessories like the alternator or AC compressor. One nut locks the accessory in place, so you have to loosen that one, the other lets you adjust the tension. Not sure about the new Honda's. They may use belt tensioner pullies which are not adjustable.

Haynes for my max said it depends on distance. IIRC (probably I don't) 1/4" is ok if it's around 6 inches but if it's like 10-12" then you can get half an inch of deflection. It didn't say how hard you can push, though, but you'll find that it easily moves about as far as it wants to and then requires a great deal more effort to keep pushing a little, so I just pushed "fairly hard" when I did mine recently. I don't think it's terribly exact anyway and presumably (I presume) a ballpark is sufficient for this thing.
