If you suspect air in your power steering system, the problem is usually *not* trapped air, but rather something else:
* Low fluid: This is the most common cause of power steering problems. Check the fluid level in the reservoir and add the correct type of power steering fluid (check your owner's manual). Low fluid is usually accompanied by whining noises.
* Leaking fluid: Inspect all hoses, lines, and the reservoir for leaks. A leak will introduce air into the system as it loses fluid. This requires repair, not just bleeding.
* Faulty power steering pump: A failing pump may not be able to circulate the fluid efficiently, leading to symptoms similar to air in the lines. This is a more serious problem requiring replacement.
* Clogged filter or screen: A restricted filter in the system can restrict flow and act like an air blockage.
Instead of trying to "bleed" the system (which is usually ineffective), focus on these steps:
1. Check and Top Off Fluid: Add the correct power steering fluid to the reservoir until it reaches the "full" mark. Use the correct type specified in your owner's manual.
2. Inspect for Leaks: Carefully examine all hoses, lines, and the reservoir for leaks. Look for wet spots, discoloration, or fluid dripping.
3. Start the Engine and Turn the Steering Wheel: With the engine running, slowly turn the steering wheel fully left, then fully right, repeatedly. Do this several times. This will help to circulate the fluid and potentially dislodge any minor air bubbles.
4. Check Fluid Level Again: After this process, check the fluid level again and top it off if necessary.
5. Listen for Noises: Pay attention to any whining noises. These are often indicators of low fluid or a failing pump.
If the power steering problems persist after checking and topping off the fluid, and inspecting for leaks, then professional help is needed. A mechanic will be able to diagnose the underlying cause (likely a leak or a failing pump) and perform the necessary repairs. Attempting further "bleeding" procedures without addressing the root cause will likely be futile.
