There is this weird sound coming from the engine bay. There isn't any warning lights saying anything is wrong, and the car drives normal. What could it be?

Coming from the front of the engine, middle, back, ?? It sounds like a bad water pump bearing to me, but it really depends on what area the noise is coming from. With the engine off, and cold, try to wiggle the pulley for the water pump.. if it moves back and forth, its bad.

 

I was thinking one of the pulleys as well... Hard to say for sure without actually being there... may be beneficial to pull the belt off and spin each one and try to rock them checking for play...

 

It was a bad water pump, thanks for the help guys

 

So what'd i win?

Glad you got it taken care of!
