1. Check Fluid Level: Ensure the power steering fluid reservoir is filled to the proper level (check your owner's manual). Use the correct type of power steering fluid recommended for your vehicle.
2. Start the Engine: With the engine OFF, turn the steering wheel lock-to-lock several times to help move any trapped air.
3. Run the Engine: Start the engine and let it idle. Keep your hands off the steering wheel. The pump will circulate the fluid. Listen for any unusual noises (whining, groaning) which could indicate air or other problems.
4. Turn the Steering Wheel: Slowly and smoothly turn the steering wheel lock-to-lock several times. This helps move the air bubbles towards the reservoir. Do this repeatedly for a minute or two.
5. Check Fluid Level Again: Turn the engine OFF and check the fluid level. Top it off if necessary. You might see some bubbles initially.
6. Repeat: Repeat steps 3-5 until you don't see any more air bubbles in the reservoir and the steering feels normal. It may take several minutes.
7. Test Drive: After the fluid level is stable and the steering feels normal at idle, take a short test drive, turning the steering wheel frequently.
Important Considerations:
* Power Steering Pump Damage: If you hear significant groaning or whining *after* trying this procedure, you might have already damaged the power steering pump by running it with air in the system. This is a serious problem requiring professional attention.
* Low Fluid: Running the pump low on fluid will quickly damage it. Always ensure the fluid reservoir is properly filled before starting the engine.
* Leaks: Double-check all your connections after replacing the hose for any leaks. A leak can introduce air continuously.
* Professional Help: If you're uncomfortable performing this procedure yourself, or if the problem persists after trying these steps, take your car to a qualified mechanic.
This process relies on the power steering pump circulating the fluid and forcing the air out. There's no specific "bleeder valve" in most power steering systems. If after several attempts of this procedure you still have problems, you may need a professional to help diagnose whether there's another underlying issue.
