Car squeaks loudly
 
There is squeak near the front if the car..what could it be? a belt!?!

If it is doing it with the engine running and the car not moving it is most likely a pulley or idler. If you havent changed them in the last 50,000 miles, I would replace them all as well as new belts. Cheap insurance against catastrophic damage.

....or make use of the "Search Button"...to help where to start looking.

Can be one or more of several reasons..


Good luck!

Is it bad if it is not replaced right away?

A failing tensioner or idler pulley will chirp a little on cold starts to warn you. Probably could go for weeks on it. A continuous LOUD squeak is either a pulley that will fail soon, or a worn/stretched belt that's slipping and needs replacement or has become contaminated with a fluid and is slipping. You could also have an accessory that's binding (water pump, AC, power steering pump) and causing belt to slip.

The risk is if a pulley locks up and you throw/shred the belt, it can do damage slapping around in there (destroy cooling fan, coolant expansion tank, etc.) and when you lose the belt, the water pump stops and the engine overheats. You don't want that.
