1. Preparation
  • Tools Required: OBD-II scanner, mechanic's stethoscope or screwdriver, jack stands, multimeter.
  • Safety Warnings: Ensure the vehicle is on a level surface and that jack stands are used for safety.
2. Addressing the Whirring Noise

A. If Related to Belts or Pulleys

  1. Remove Engine Cover: If applicable, remove the engine cover using a socket set.
  2. Inspect and Replace Serpentine Belt:
    • Check for cracks or fraying.
    • If damaged, loosen the tensioner and remove the old belt.
    • Install a new belt, ensuring it is properly routed and tensioned according to specifications (refer to the service manual for routing diagrams).

B. If Related to the Alternator
