This type of noise must be heavy and it is often quite simple to relate it with one of these belts. To verify, do not hesitate to open your bonnet, engine running cold and check the source of this noise, the serpentine or driving belt being exposed, it should not be too difficult for you to locate a belt noise on your Infiniti M. The cause of this problem can be in connection with the damper pulley, which works as a damper to reduce irregularities in the tension in the motor cycle and therefore in the energy transmission to the belt. This results in a loose belt that will jerk. However, you still have an opportunity that this phenomenon is annodine. As the serpentine belt of your Infiniti M is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions.
