belt noise came back...

I changed my belts (all with OEM) maybe two or more months ago. Took road trip and probably put maybe 1k miles on it. After that I started to get some belt squeal, I tightened the belts up - figured they may have stretched a little since they were new and the noise/sound went a away. I just drove about 60 miles round trip to visit a friend and the sound is back.

The first time the sound appeared was when I made this trip last time - its all freeway but a portion of it is inclined, could this perhaps stressed the pulleys? Is it likely that the belts have stretched more? I opened the hood at the gas station to see if I noticed anything odd. On the Water Pump belt there seems to maybe be some liquid on the belt..? Its hard to tell if that is what it is but the other two belts have nothing in the groves. I took some pictures but it was with my Iphone and at night - though I have the flash on.

If the waterpump was leaking, is it more likely that it would be leaking severely or slightly? I didn't notice liquid anywhere else and again, I'm not sure if what is in the grooves of the waterpump belt is liquid or maybe wear from the pulleys?

thoughts?

 

water bump can be leaking internally, hows fluid levels?

but what it really sounds like is the bearing going bad. loosen/take off the belt, and wiggle around the pulleys, any of them have play they shouldnt?

 

fluid levels are good.

I loosen the belts last time and checked to make sure nothing was wiggling - everything seemed to be ok. I thought maybe one of the pulleys for either the WP or PS were messed up but they seem to turn alright, freely, no grinding or anything..

 

well, old school trick to help with belt slip (if the pullys get to polished) fough them up a bit with sand paper, and soap the belt. bar soap. dove works great

 

soap the belt? like with a raw bar? - wouldn't soap cause for more possibly slippage?

Thanks.

 

i always just used dove. dunno gf's old man told me about that. my old man said that, and rough the glaze on the pulleys, hopefully in the am someone can provide more insite.

 

talcom powder on the belts stops the squeel they say.

 

Really? Could it just be the belt loosened a little? Does that happen often? The belts probably have 2500 miles on them

 

Some belts just come manfactured with a squeal no matter what...the compound it was made from could just be a LITTLE off and it'll ruin the entire batch.

Belt's are a get lucky run of the mill thing.
Some squeal, some squeal sometimes..some will NEVER ever squeal.
