Bleeding a power steering system is typically done to remove air bubbles that can enter the system during repairs or fluid changes. Removing this air ensures smooth operation and prevents noise or damage. Based on the provided reference, here is a method for bleeding the power steering system:
Steps to Bleed Your Power Steering System
The core process involves circulating fluid and air out of the system. Follow these steps carefully:
- Slightly Open the Bleed Valve: Begin by cracking open the bleed valve slightly. This allows trapped air and some fluid to escape.
- Turn the Steering Wheel Lock-to-Lock: With the bleed valve open slightly, turn the steering wheel slowly from one lock position (all the way to the left) to the other lock position (all the way to the right) several times. This action pumps fluid through the system and pushes air towards the bleed valve.
- Monitor and Top Off Fluid: Watch the fluid coming out of the bleed valve or the reservoir. Once the air is no longer visible (you should see only fluid without bubbles), top off the power steering fluid in the reservoir to the recommended level.
- Further Steering and Final Check: Turn the steering wheel a few more times lock to lock. This helps ensure any remaining small air bubbles are expelled or absorbed.
- Check Fluid Level Before Driving: Before operating the vehicle, check the power steering fluid level once more and adjust if necessary.
Following these steps helps remove air from the system, restoring proper power steering function.
Why Bleeding is Important
- Removes Trapped Air: Air in the power steering lines and pump can cause noise (like whining) and inconsistent assist.
- Ensures Smooth Operation: A properly bled system provides smooth, reliable power assist for steering.
- Prevents Potential Damage: Running the pump with air can cause it to work harder and potentially lead to premature wear.
By carefully following the steps outlined above, you can effectively bleed the air from your power steering system, improving its performance and longevity.
