What happens if power steering fluid is never changed?

[LeIker]

Not changing the power steering fluid for a long time can lead to heavier steering wheel operation, and in severe cases, may cause damage to the steering gear. The method for replacing power steering fluid is as follows: 1. Prepare a bottle of original power steering fluid; 2. Open the cap of the power steering fluid reservoir; 3. Lift the vehicle and remove the underbody guard; 4. Use pliers to loosen the oil pipe clamp and move it aside; 5. Disconnect the oil pipe to drain the fluid; 6. Turn the steering wheel left and right to expel the old power steering fluid; 7. After draining the fluid, reinstall the power steering pipe to its original position and secure the clamp back in place; 8. Lower the vehicle, add new power steering fluid while turning the steering wheel; 9. Use an oil extractor to remove surface foam, start the vehicle and turn the steering wheel left and right 4 to 5 times to expel air; 10. After expelling air, turn off the engine and check if the fluid level is normal; 11. Start the vehicle, lift it to check for any oil leaks or seepage from the power steering pipe, clean any oil stains, and reinstall the underbody guard.
