Troubleshooting Power Steering Issues: Bleeding the System

Are you experiencing issues with your power steering, such as no power steering after installing a new power steering rack and a new pump? This article aims to guide you through the process of bleeding the power steering system to resolve these issues. Bleeding the system can be a straightforward task if done correctly, and in this article, we will break down the process step by step.

Why Tune Up the Power Steering System?

Power steering systems are crucial for safe driving, especially in modern vehicles. If you've recently installed a new power steering rack and pump, it is possible that the system needs to be bled.

How to Bleed the System

The process of bleeding the power steering system can be summarized into a series of steps. This guide will help you identify and address any blockages or air bubbles that might be causing the issue.

Equipment Needed

Correct power steering fluid Reservoir Jack and jack stands (if necessary) Assistant for topping up the reservoir Jack under the front crossmember or a suitable jacking point (for front-wheel-drive vehicles) Steering wheel turned to one lock position but not pulled

Step-by-Step Bleeding Process

Step 1: Fill the Reservoir with the Correct Fluid
Start by filling the power steering reservoir with the correct type of fluid. Consult your vehicle's manual to ensure you use the right fluid.

Step 2: Engine Idle
Start the engine and let it idle until the reservoir level is stable. As the system runs, top up the reservoir as needed to maintain the correct fluid level.

Step 3: Jack Car and Secure
Position the vehicle on a level surface. Jack up the front of the vehicle and secure it with jack stands. For front-wheel-drive vehicles, ensure the jack point is not on the sump or bottom of the transmission. Make sure the handbrake/parking brake is engaged to prevent the vehicle from moving.

Step 4: Turn Steering Wheel
Gradually turn the steering wheel towards one lock position. Do not pull the wheel when it reaches the lock; just let it lightly touch. Avoid generating high pressure by turning the wheel with your finger, as this could aerate the oil.

Step 5: Check Reservoir Level
Once the steering wheel is at full lock, check the reservoir level. Slowly turn the steering wheel in the opposite direction until full lock is reached, again without pulling the wheel against the lock.

Step 6: Repeat Until Stabilization
Continue repeating steps 4 and 5 until the oil level in the reservoir stabilizes. At this point, you should be able to generate some pressure at the lock and have the system operating normally.

Step 7: Test for Pressure
If the system still does not provide pressure, the pump vanes may be stuck with preservative, especially if the pump is new. In this case, you may need to consider exchanging the pump or seeking professional assistance from a power steering specialist.

Step 8: Rebuild and Reinstall
For more persistent issues, disassemble the pump, wash all parts using a suitable solvent, and reassemble the system while ensuring all parts are lubricated with power steering oil. If necessary, seek professional assistance with specialized tools and seal protectors.

Conclusion

Following these steps can help you diagnose and address power steering issues effectively. Bleeding the system is a crucial step in ensuring that your power steering operates smoothly and safely. By taking the time to bleed the system correctly, you can extend the life of your power steering components and improve overall vehicle performance.

Additional Tips

Some vehicles may require faster bleeding processes, such as on assembly lines. For these situations, high vacuum pumps are used to achieve a perfect level of vacuum, allowing for an accurate amount of fluid to be introduced and ensuring full system functionality.
