I needed a new serpentine belt so I took it to the dealer and they replaced it under warranty. There is a ticking now coming from my engine. It sounds like its coming from the belt or one of the pullies. I went back the the dealer and asked what the heck the noise was and they just said the belt was breaking in. The car is running fine...it just ticks...and the tick is pretty consistent with each revolution of the belt. Is this normal?
