Quick Overview
- A leak in the power steering system could be caused by a faulty hose, seal, or pump.
- Stiff steering can be caused by low power steering fluid, air in the system, or a faulty power steering pump.
- Signs of a failing power steering pump include stiffness or noise in the steering, leaks, or a whining sound when turning the wheel.
If you’re experiencing steering issues in your Chevy Silverado, it may be time to bleed the power steering pump. Bleeding removes air from the system, which can cause problems such as stiffness, noise, or leaks. Here’s a detailed guide on how to bleed your Chevy Silverado power steering pump:
Safety Precautions
- Park your Silverado on a level surface and engage the parking brake.
- Allow the engine to cool down completely before starting the bleeding process.
- Wear safety glasses and gloves to protect yourself from fluid spills.
Tools and Materials
- Power steering fluid (GM Dexron VI is recommended)
- Rags or paper towels
- Funnel
- Wrench or socket set
Step-by-Step Instructions
1. Locate the Power Steering Pump
The power steering pump is typically located on the front of the engine, near the serpentine belt. It will have a reservoir attached to it.
2. Check Fluid Level
Open the reservoir cap and check the fluid level. If it’s low, fill it to the “Full” mark using Dexron VI fluid.
3. Turn the Steering Wheel
Turn the steering wheel fully left, then fully right, several times. This helps circulate the fluid through the system and remove any trapped air.
4. Locate the Bleeder Screw
The bleeder screw is usually located on the top of the steering rack or pump. It’s a small, slotted screw.
5. Place a Rag Underneath
Place a rag or paper towel underneath the bleeder screw to catch any fluid that comes out.
6. Loosen the Bleeder Screw
Use a wrench or socket to loosen the bleeder screw about one-quarter turn. You should see power steering fluid start to leak out.
7. Turn the Steering Wheel
While the bleeder screw is open, turn the steering wheel back and forth several times. This will help force any remaining air out of the system.
8. Tighten the Bleeder Screw
Once you no longer see any air bubbles coming out of the bleeder screw, tighten it back up.
9. Check Fluid Level Again
Open the reservoir cap and check the fluid level. If it’s low, fill it to the “Full” mark using Dexron VI fluid.
10. Start the Engine
Start the engine and let it idle for a few minutes. Turn the steering wheel back and forth several times to circulate the fluid.
11. Repeat the Bleeding Process
If you still notice any stiffness or noise in the steering, repeat the bleeding process until the symptoms disappear.
Troubleshooting
Why is my power steering fluid leaking?
A leak in the power steering system could be caused by a faulty hose, seal, or pump. Inspect the system for any visible leaks and repair or replace the damaged components as needed.
Why is my steering wheel stiff?
Stiff steering can be caused by low power steering fluid, air in the system, or a faulty power steering pump. Check the fluid level, bleed the system, and test the pump for proper operation.
How often should I bleed my power steering system?
Bleeding the power steering system is not typically necessary on a regular basis. However, it may be required if you experience any steering problems, such as stiffness, noise, or leaks.
In a nutshell
Bleeding the power steering pump in your Chevy Silverado is a relatively straightforward procedure that can be completed in about 30 minutes. By following these steps, you can restore your steering system to optimal performance.
