Understanding 2017 Chevy Traverse Power Steering Fluid Essentials
The correct power steering fluid for a 2017 Chevy Traverse is GM Part Number 89021183, which is a Dexron VI automatic transmission fluid (ATF). This specific fluid is essential for lubricating and cooling the power steering system components, ensuring effortless steering and preventing premature wear.
- Use Dexron VI ATF for your 2017 Chevy Traverse power steering.
- GM Part Number 89021183 is the specified fluid.
- Proper fluid level prevents system damage and ensures smooth steering.
- Regular checks are vital for steering system health.
Your 2017 Chevy Traverse relies on hydraulic power steering, a system that uses fluid pressure to assist the driver in turning the wheels. This fluid acts as a lubricant for the pump, rack, and seals, while also helping to dissipate heat generated during operation. Using the wrong type of fluid can lead to corrosion, seal degradation, and ultimately, costly repairs to the power steering cylinder or other integral parts. It is imperative to acknowledge that power steering fluid is not interchangeable with brake fluid or other vehicle fluids; using the correct formulation is paramount.
Why Dexron VI ATF is Specified
General Motors specifically mandates Dexron VI ATF for the power steering system in many of its vehicles, including the 2017 Traverse. This fluid offers superior viscosity stability across a wide temperature range, excellent oxidation resistance, and improved shear stability compared to older formulations. These characteristics are vital for consistent performance in both frigid winter conditions and hot summer driving. This mechanism is critical for consistent steering feel.
Power Steering Fluid Capacity for the 2017 Traverse
While the exact capacity can vary slightly due to refill methods and system bleed-off, a typical power steering fluid capacity for the 2017 Chevy Traverse is approximately 1 quart (0.95 liters). It is always best to start with a fresh quart and add as needed, carefully monitoring the reservoir level. Overfilling can cause foaming and system damage, so precision is key.
When topping off or flushing the system, ensuring you have enough fluid on hand prevents interruptions. While the system typically holds around a quart, purchasing two quarts is a prudent approach, allowing for any minor spills or the need for a more thorough flush if required.
Diagnosing and Servicing Your Traverse's Power Steering System
What are the tell-tale signs that your 2017 Chevy Traverse's power steering system might need attention, specifically related to its fluid?
Common Symptoms of Low or Contaminated Power Steering Fluid
Drivers often first notice a change in steering effort. If turning the wheel becomes noticeably harder, especially at low speeds or when stationary, it's a strong indicator. Other symptoms include:
- Whining or groaning noises from the power steering pump, particularly when turning the wheel.
- A feeling of sponginess or looseness in the steering.
- Leaking fluid under the vehicle, usually a reddish-brown color (if Dexron VI is used).
- Difficulty returning the steering wheel to center after a turn.
These symptoms often point to issues like a low fluid level, air in the system, or a failing power steering pump. Understanding this principle is fundamental to preventing further damage.
Don't ignore these warnings; a failing power steering pump can leave you with a completely unresponsive steering wheel, creating a dangerous driving situation. Prompt attention can save you from more extensive, costly repairs.
Power Steering Fluid Services and Best Practices
While there isn't a strict mileage-based replacement interval for power steering fluid in the 2017 Chevy Traverse, it's a component that benefits from periodic inspection and service. Most manufacturers recommend checking the fluid level and condition during routine maintenance, such as oil changes. If the fluid appears dark, has a burnt smell, or contains debris, a power steering fluid flush and replacement are advised.
Inspect your power steering fluid level at least every other oil change, or whenever you notice changes in steering feel or hear unusual noises. Use a clean funnel and a lint-free cloth to avoid introducing contaminants.
A complete power steering service involves draining the old fluid, flushing the system with a specialized cleaner (if recommended by a technician), and refilling with the correct Dexron VI ATF. This process removes accumulated contaminants and ensures the system operates with fresh, effective lubrication. Such precision is paramount for system longevity.
Regularly checking and maintaining your power steering fluid is a low-effort task with a high reward in steering system reliability and safety.
DIY Fluid Check vs. Professional Service
Checking the fluid level is straightforward. Locate the power steering reservoir (consult your owner's manual if unsure), remove the cap, and check the fluid against the markings on the dipstick or reservoir wall. Ensure the engine is off and has cooled down for an accurate reading. If you're uncomfortable performing a flush or suspect a leak, it's best to consult a qualified mechanic. They have the specialized tools and expertise to handle power steering fittings and ensure the system is properly bled after service.
Troubleshooting Common Power Steering Fluid Issues
Is your 2017 Chevy Traverse's steering acting up? Let's troubleshoot common power steering fluid-related problems.
Addressing Air in the Power Steering System
Air can enter the system if the fluid level drops too low or if components have been recently replaced. Symptoms include a whining noise that changes pitch with engine RPM and a foamy appearance in the reservoir. To resolve this, ensure the reservoir is filled to the correct level with Dexron VI ATF. Then, with the engine running, turn the steering wheel slowly from lock to lock several times. This helps to purge air bubbles. Repeat until the noise subsides and the fluid is clear. If the problem persists, there might be a leak allowing air ingress.
This bleeding process is a fundamental step after any fluid top-off or component replacement to restore normal operation.
Dealing with Leaks and Contamination
Leaks are often the culprit behind low fluid levels. Common leak points include hoses, seals, and the power steering pump itself. If you discover a leak, it's crucial to identify the source and repair it promptly. Small leaks can be temporarily managed by topping off, but a permanent fix is always recommended. Contamination, such as dirt or coolant mixing with the power steering fluid, can severely damage the pump and rack. If contamination is suspected, a full system flush is necessary.
Keep a small amount of the specified Dexron VI ATF in your vehicle for quick top-offs in case of minor leaks. Always use a clean container to prevent introducing dirt.
When to Consider a Full Power Steering Flush
A power steering flush is recommended if the fluid is dark, burnt-smelling, or visibly contaminated with debris. While some owners opt for DIY flushes using a fluid extractor and fresh Dexron VI ATF, it's a task best left to professionals if you lack experience. They can ensure the system is completely flushed and properly refilled, preventing costly damage. This is especially true when dealing with complex systems or suspected internal wear. Our analysis indicates that proactive flushing can extend the life of major components.
The cost of a professional power steering service is significantly less than replacing a power steering pump or rack, making it a wise preventative measure.
