A Guide to the 2006-2010 Pontiac G6 Hydraulic Power Steering Pump
Solving whining noises and stiff steering in your V6-equipped Pontiac G6.
- First, confirm your G6 has a V6 engine, as it likely uses the hydraulic pump this guide covers, not the recalled electric system.
- Symptoms include whining noises when turning, stiff steering, and fluid leaks.
- Replacing the pump is a manageable DIY job, but requires a special pulley remover/installer tool.
- Aftermarket pumps are affordable, but quality varies; new units are generally more reliable than remanufactured ones.
Is Your Power Steering Pump Failing?
A failing power steering pump on a 2006-2010 Pontiac G6 gives clear warning signs. If you notice these symptoms, it's time to inspect the system before the pump fails completely.
| Symptom | Description |
|---|---|
| Whining or Groaning Noises | This is the most common sign. You'll hear a distinct whining noise from the engine bay that gets louder when you turn the steering wheel. |
| Stiff Steering | The steering wheel becomes difficult to turn, especially at low speeds or when parking. It feels like you're driving a car without power steering. |
| Fluid Leaks | You may see reddish or brown fluid puddles under the front of your car. The pump itself might look wet or grimy from leaking fluid. |
| Frothy Fluid | If you check the power steering reservoir and the fluid looks bubbly or foamy, it means air is getting into the system. This is often caused by a bad seal in the pump. |
Known Issues: Hydraulic Pump vs. Electric Steering Recall
Important: Check Your System Type
The Pontiac G6 was built with two different types of power steering. V6 models (3.5L, 3.6L, 3.9L) typically use a hydraulic power steering pump, which is a belt-driven part with fluid. Most 4-cylinder models use an Electric Power Steering (EPS) system, which uses an electric motor and has no pump or fluid.
General Motors issued major safety recalls for the electric power steering system, which could suddenly fail. These recalls do not apply to the hydraulic power steering pump. If you are experiencing a complete and sudden loss of steering assist accompanied by a warning on your dash, you may be affected by the EPS recall, not a failing hydraulic pump.
Choosing the Right Aftermarket Power Steering Pump
When replacing the power steering pump on your G6, you have several aftermarket options. OEM parts from a dealer are the most expensive choice. Aftermarket brands offer a more affordable alternative, but quality can vary.
- Premium Aftermarket (e.g., AC Delco New, some PWR New): These are often 100% new units designed to meet or exceed original specifications. They offer the best reliability outside of an OEM part but come at a higher price point within the aftermarket range.
- Standard Aftermarket / Remanufactured (e.g., Cardone, BBB Industries): These brands are widely available and offer a balance of cost and quality. Cardone and BBB are major players who offer both new and remanufactured units. Reviews for their remanufactured pumps can be mixed; some work perfectly, while others may have issues out of the box. A lifetime warranty can provide peace of mind if you choose a remanufactured part.
- Economy (e.g., DNJ Engine Components, other private labels): DNJ is primarily known for internal engine parts but offers other components as a budget-friendly option for stock replacements. These pumps are the most affordable but may not have the same longevity as premium options.
Pro Tip: Get the Pulley Tool
Most new and remanufactured power steering pumps for the G6 do not come with a pulley. You will need to remove the pulley from your old pump and install it on the new one. This requires a specific power steering pump pulley remover/installer tool, which can be rented from most auto parts stores.

Frequently Asked Questions
Can I replace the G6 power steering pump myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill. 🎬 Watch this step-by-step guide for replacing the pump on V6 models. The process involves removing the serpentine belt, unbolting the pump (which may require removing an engine mount on some models), swapping the pulley with a special tool, installing the new pump, and bleeding the system of air. The most critical step is properly bleeding the system afterward to prevent noise and damage to the new pump.
🎬 Learn how to bleed the power steering system the right way.What kind of power steering fluid does the Pontiac G6 use?
Always check your owner's manual for the exact specification. Most GM vehicles of this era use a standard power steering fluid that meets GM OE requirements. Using the correct fluid is critical for the life of the pump and seals.
Is a noisy pump always a bad pump?
Not always, but usually. A whining noise can also be caused by very low power steering fluid or a loose serpentine belt. Always check your fluid level first. If the fluid is low, top it off and check for leaks. If the noise persists or the fluid is frothy, the pump is likely failing.
What's the difference between a new and a remanufactured pump?
A new pump is made with 100% new components. A remanufactured (reman) pump starts with a used OEM core (the main body). It is disassembled, cleaned, and rebuilt with new seals, bearings, and other wear items. Quality can vary widely on reman parts, but they are an affordable and often reliable option.
