Is There a Rustling Friction Noise from the Engine?

[LawsonAnn]

There are several reasons why the engine may produce a rustling friction noise: Bearing Failure: This can cause a rustling sound, which may turn into a rattling or squealing noise if severe. Immediate inspection and repair are recommended. Belt Aging or Looseness: Since the belt is made of rubber, it can harden in cold weather when the engine is cold. Upon startup, you may hear a sharp noise, but it typically disappears after pressing the accelerator a few times or allowing the car to warm up. To fix this, use an appropriate wrench to loosen the screws slightly—just enough to allow the car's motor to move freely.
