1. Check Fluid Level: Before starting, ensure the power steering fluid reservoir is filled to the correct level (check your owner's manual for the specific mark). Use the correct type of power steering fluid specified by the manufacturer.
2. Start the Engine (with caution): Start the engine and let it idle. Important: Turn the steering wheel slowly and fully lock-to-lock several times. This helps to circulate the fluid and dislodge any air bubbles.
3. Monitor Fluid Level: Keep an eye on the fluid level in the reservoir. If the level drops significantly, add more fluid as needed. This is where air might be getting expelled.
4. Listen for Noises: Listen for any unusual whining or groaning sounds. These could indicate air in the system or other problems. If the noises persist after several minutes of turning the wheel, there might be a more significant issue.
5. Check for Leaks: Inspect all connections and hoses for leaks after running the engine. A leak indicates a problem that needs attention *before* continuing to operate the vehicle.
If the problem persists after this procedure:
* Air in the System (Less Likely): If you are absolutely sure you've replaced the pump correctly and tightened all connections, it's unlikely there's significant air trapped that won't work itself out with the above steps.
* Faulty Pump: The new pump might be defective.
* Other Issues: The problem may not be related to the pump itself; there could be a blockage in the lines, a damaged rack and pinion, or another component failure.
Recommendation: If the problem persists after following these steps, it's best to take your vehicle to a qualified mechanic. Trying to force-bleed the system or guess at other solutions could potentially damage the power steering system or even lead to injury.
