It's started to get really cold here...dont think i dont know what cold is just because i live in florida...i used to live in north carolina...it got cold there too. anyways, recently my belts squeak whenever i start my car, so i rev it up some then it'll stop...its so loud and obnoxious! i know the problem i have is "squeaky belts", but what i want to know is why this is happening...

easy,
elementary phisics= when object is hot it is smaller, when it is cold it is expanding and becomes bigger.

solution ! ?

isn't it the opposite ?
elementary physics..
Loosen the belt abit.
man you need some studying to do !Originally posted by shepherd79

Check your alternator belt tension. You'll probably find it's a bit too loose. Tighten the tensioning nut a little and you should be fine.Originally posted by GDGuy11B

P.S. increased temp --> increased size...unless you're freezing water, that's different.

mike,
what do you mean i need some study to do?
explain to me why it squeaks when it is cold but when it is hot it is not?
i would like to hear a good reason.

When it's cold the belt material is less flexible, less grippy, etc. A little more tension will make it grip the pulleys better...unless it's already way too tight. I've never had one like that so I'm not sure if they make a noise or not.

Cold rubber has a much lower frictional coefficient (Kf) and is harder than wam/hot rubber. Low Kf means slippage and high Kf means traction. During slippage heat is produced by the abrasion that warms the rubber, making it softer, increasing Kf, and thus improving traction with the wheel/pulley. As a result the belt stops squeaking.
Think about how those f1/cart/nascar drivers warm up their tires in zigzags so they can get better traction.
Just to reiterate, tighten that belt because it will get glazed by the high heat produced during slippage (thus more slippage) and you will have to change it sooner than the doctor ordered.

what ever. take 10mm range and tighten the belts if it is squeaks.
