why does my Genesis G70 make a whining noise when I start it

Solution

1. Preparation

• Tools Required: OBD-II scanner, flashlight, mechanic's stethoscope, socket set.
• Safety Warning: Ensure the vehicle is in park and the parking brake is engaged before starting work.

2. Inspect and Replace Accessory Belts

• Sub-steps:
  1. Turn off the engine and allow it to cool.
  2. Locate the serpentine belt routing diagram (usually found on a sticker in the engine bay).
  3. Use a ratchet and socket to relieve tension on the belt tensioner and remove the serpentine belt.
  4. Inspect the belt for cracks, fraying, or glazing; replace if necessary.
  5. Reinstall the new or inspected belt according to the routing diagram.

3. Check and Refill Power Steering Fluid

• Sub-steps:
  1. Locate the power steering reservoir.
  2. Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
  3. If low, add the recommended power steering fluid as specified in the owner's manual.
  4. Replace the cap securely.

4. Inspect and Service Alternator

• Sub-steps:
  1. Disconnect the negative battery terminal to prevent any electrical shorts.
  2. Visually inspect the alternator for any signs of wear, such as loose wires or damaged bearings.
  3. If necessary, remove the alternator using a socket set, noting the routing of any wiring connections.
  4. Replace with a new alternator if the current one is faulty.
