2010 Chevrolet Bolt Power Steering Pump Problems: How To Fix It

How to Fix Power Steering Pump Issues

This guide addresses common power steering pump issues encountered by 2010 Chevrolet Bolt owners. We'll cover potential causes, diagnostic steps, and fixes based on real owner experiences. One owner shared, "While taking off the banjo bolt to the power steering pump, I noticed that there's no copper crush wires. The new pump is provided with them."

Symptoms

Owners have reported a few symptoms related to the power steering system on their 2010 Chevrolet Bolt vehicles. A primary concern revolves around issues encountered when replacing the power steering pump itself.

For instance, some owners found that essential components, like copper crush washers for the banjo bolt, were missing during pump replacement. This discovery often prompts a need to source the correct parts for a proper installation. The absence of these components can lead to leaks and improper system function.

Another symptom stems from concerns about maintaining vehicle performance, even when adding performance-enhancing components. Owners seeking to increase horsepower while adhering to smog regulations face the task of ensuring that modifications don't negatively impact the power steering or other systems. This might not be a direct pump failure symptom but rather a system-level consideration.

Loss of power or braking power can also be a symptom. While not directly related to the power steering pump alone, some owners have experienced it, and it is important to note in order to address the problem.

Most Likely Cause

Based on owner reports, the most likely cause is missing or incorrect components during power steering pump replacement. This includes the absence of copper crush washers or similar hardware needed to properly seal the banjo bolt connection to the pump. It’s vital to ensure all necessary components are present before finalizing the installation. This can lead to leaks and performance issues. Another potential cause stems from modifications to other car systems that can affect the pump.

How to Diagnose

Before starting, make sure that you have the right parts with the correct sizes.

To diagnose power steering pump problems on your 2010 Chevrolet Bolt, follow these steps:

1. Visual Inspection: Start by visually inspecting the power steering pump, hoses, and connections for any signs of leaks. Pay close attention to the area around the banjo bolt connection.
2. Fluid Level Check: Check the power steering fluid reservoir and ensure it’s filled to the correct level. Low fluid can indicate a leak in the system.
3. Component Check: Make sure that you have all of the components needed. As one owner reported, "While taking off the banjo bolt to the power steering pump, I noticed that there's no copper crush wires. The new pump is provided with them." (source)
4. Listen for Noises: Start the engine and listen for any unusual noises coming from the power steering pump. Whining, groaning, or squealing noises can indicate a failing pump.
5. Steering Effort: Check the steering effort at different speeds. Increased effort, especially at low speeds, can suggest a pump problem.
6. Check for Leaks: Turn the steering wheel from lock to lock several times while observing the pump and hoses for leaks.

Tools Needed:

• Safety glasses
• Gloves
• Wrenches
• Socket set
• Torque wrench
• Drain pan
• Power steering fluid
• Shop towels
• Inspection light

Step-by-Step Fix

Here's a step-by-step guide to address power steering pump issues, particularly the missing copper crush washers:

1. Gather Parts: Ensure you have all the necessary parts, including the correct copper crush washers for the banjo bolt. "The new pump is provided with them", as one owner pointed out (source).
2. Preparation: Position a drain pan under the power steering pump to catch any spilled fluid.
3. Remove Banjo Bolt: Carefully remove the banjo bolt from the power steering pump. Take note of the orientation of any existing washers or seals.
4. Inspect Connections: Check the banjo bolt and pump fitting for any damage or corrosion. Clean as necessary.
5. Install Copper Crush Washers: Place a new copper crush washer on each side of the banjo fitting where it connects to the pump.
6. Reinstall Banjo Bolt: Reinstall the banjo bolt, ensuring it is properly aligned and seated.
7. Torque to Spec: Torque the banjo bolt to the manufacturer's specification using a torque wrench. Overtightening can damage the bolt or pump.
8. Refill Fluid: Check that you have enough fluids, and then refill the power steering fluid reservoir to the correct level.
9. Bleed System: Bleed the power steering system to remove any air. Start the engine and turn the steering wheel from lock to lock several times. Check the fluid level and add more as needed.
10. Test Drive: Take the vehicle for a test drive and check for any leaks or unusual noises. Verify that the steering effort is normal.
