my Volkswagen Golf makes a whining noise when I accelerate what’s wrong

Solution

1. Preparation

• Gather tools and parts needed.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to ensure safety.

2. Inspect and Replace Drive Belt

• Sub-steps:
  1. Remove any covers obstructing the drive belt.
  2. Visually inspect the belt for cracks, fraying, or glazing.
  3. If damaged, use a socket set to loosen the tensioner and remove the old belt.
  4. Install the new drive belt, following the routing diagram typically found on a sticker in the engine bay.
  5. Re-tighten the tensioner to secure the new belt.

3. Check Pulleys and Tensioner

• Sub-steps:
  1. Spin each pulley by hand to check for smooth operation and noise.
  2. Replace any noisy or stiff pulleys using a socket set.
  3. Inspect and, if necessary, replace the tensioner if it does not hold the belt securely.

4. Verify Alternator and Power Steering Pump

• Sub-steps:
  1. With the engine running, listen closely to the alternator and power steering pump.
  2. If noise is detected, consider replacing the affected component.
  3. Disconnect the battery before replacing any component.
