Heard a chirping noise coming from my engine . I took the the car in and was told the belt tensioner was

bad. They replaced the tensioner and I still heard the chirping noise. Took the car back to mechanic and he replaced the belt. Problem was still there, so I finally took the car to the dealer and after inspecting the

parts that were taken off the car our conclusion was that these parts were not causing the noise. An inspection

of all the pulleys found that the water pump was leaking on to the pulley. This car had only 31000 miles on it

and was serviced regularly.
