when i turn on my engine, there would be a squeaking noise and it squeaks when i drive also. after i gain speed or the engine is warm then the noise goes away. this only happens when the engine is cold or if its raining. could it be the belts? a mechanic told me it was because my power steering belt was dry. im thinking about replacing my alternator drive belt, power steering belt and the a/c belt. someone help. thanks!
