why does my Renault Clio V (2019-Present) make a whining noise when turning

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical hazards.

2. Inspect and Replace Power Steering Fluid

• Sub-steps:
  1. Locate the power steering fluid reservoir.
  2. Remove the cap and check fluid level and condition.
  3. If fluid is low or dirty, drain the old fluid using a siphon pump.
  4. Refill with the manufacturer's recommended power steering fluid (typically CHF 202 or equivalent).

3. Inspect and Replace Serpentine Belt

• Tools Required: Socket set, belt tensioner tool
• Sub-steps:
  1. Locate the serpentine belt and note the routing diagram.
  2. Use the belt tensioner tool to relieve tension and remove the old belt.
  3. Inspect the pulleys for wear or damage.
  4. Install the new serpentine belt according to the routing diagram.
  5. Ensure proper tension is applied to the belt.

4. Test Power Steering Pump

• Sub-steps:
  1. Reconnect the battery.
  2. Start the engine and observe the power steering pump operation.
  3. Listen for unusual noises (grinding or clattering).
  4. If noise persists, replace the power steering pump.

5. Inspect Steering Rack and Wheel Bearings

• Sub-steps:
  1. Raise the front of the vehicle using a jack and secure it on jack stands.
  2. Visually inspect the steering rack for leaks or damage.
  3. Check for play in the wheel bearings by spinning the wheels and listening for noise.
  4. If defects are found, replace the steering rack or wheel bearings as necessary.
