why does my Volkswagen Golf's engine make a whining noise

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Accessory Belt

• Tools Required: Socket set, torque wrench, belt tensioner tool.
• Remove the drive belt by releasing tension on the tensioner.
• Inspect the belt for any signs of wear or fraying.
• If damaged, install a new belt by routing it according to the belt diagram.

3. Check and Replace Pulleys or Tensioners

• Tools Required: Socket set, torque wrench, possibly a puller tool for stubborn pulleys.
• If any pulleys are damaged or bearings are noisy, remove them by unbolting from their mounts.
• Replace with new components, ensuring they are torqued to manufacturer specifications.

4. Power Steering Fluid Check

• Tools Required: Clean rag, funnel.
• Check the power steering fluid level; add fluid if low.
• If the fluid is contaminated, consider flushing and replacing it.

5. Reconnect Battery and Test
