Does a 2010 Chevy Malibu use power steering fluid?
Yes. The 2010 Malibu uses a hydraulic power steering system that relies on automatic transmission fluid (ATF) as the power steering fluid, rather than a dedicated steering-fluid reservoir.
In more detail, the Malibu’s power steering system operates with hydraulic fluid to assist steering effort. The exact ATF specification can vary by production date and market, but GM generally lists a Dexron-family ATF (such as Dexron II/III, with Dexron VI being commonly compatible) for these systems. Always verify the exact requirement on the reservoir cap or in the owner's manual. If you notice symptoms like stiff steering, whining sounds, or leaks, inspect and service the system promptly.
Fluid type and compatibility
Understanding the fluid requirements helps ensure you use the correct fluid and avoid damage to seals and the pump.
- The Malibu’s power steering system uses automatic transmission fluid (ATF), not a dedicated “power steering fluid.”
- GM service data for this era typically specifies a Dexron-family ATF (Dexron II/III, with Dexron VI generally considered compatible).
- Do not substitute motor oil, brake fluid, or other fluids, and avoid mixing different ATF specifications unless the manual explicitly allows it.
Conclusion: Use a Dexron-family ATF as indicated on the cap or in the manual, and avoid non-ATF fluids to protect the system’s seals and pump.
Locating the reservoir and checking the level
Follow these steps to locate the reservoir, assess the fluid level, and top up if needed.
- Park on a level surface and engine off; allow any heat to dissipate before opening the hood.
- Open the hood and locate the power steering reservoir in the engine bay; it is labeled and capped for ATF compatibility.
- Check the fluid level against the markings on the reservoir or dipstick on the cap; the level should be between the MIN and MAX marks when the engine is off and the fluid is cold.
- If the level is low, add the correct Dexron-family ATF a little at a time using a clean funnel, avoiding overfill.
- Reinstall the cap, start the engine, and slowly turn the steering wheel from lock to lock a few times to bleed air; recheck and top off if necessary.
Conclusion: Maintaining the correct ATF level and using the recommended Dexron-family fluid helps ensure smooth steering and prevents pump or seal damage.
Signs of trouble and routine maintenance
Recognize symptoms early and keep up with routine checks to prevent more serious problems.
- Stiff or hard steering, especially at low speeds, can indicate low PS fluid or air in the system.
- Whining, groaning, or squealing noises when turning the wheel often point to low fluid, air, or a failing pump.
- Visible leaks around hoses, the reservoir, or the steering rack suggest fluid loss that should be addressed promptly.
- Fluid that appears dark, dirty, or has a burnt smell may indicate degraded ATF and a need for service or a system flush.
- Always use a Dexron-family ATF and avoid mixing different specifications; if in doubt, consult a dealership or qualified mechanic.
Conclusion: Regular checks of fluid level and condition, along with prompt attention to leaks or abnormal noises, help maintain steering performance and prolong component life.
Bottom line and recommendations
The 2010 Chevy Malibu relies on hydraulic power steering that uses automatic transmission fluid (ATF) of the Dexron family. Verify the exact specification on the reservoir cap or in the owner's manual, and top up with the correct ATF if the level is low. If you experience persistent steering issues, leaks, or abnormal noises, seek service from a qualified technician to prevent damage to the pump, hoses, and seals.
Summary: The Malibu’s power steering is ATF-based, not a separate PS fluid. Use a Dexron-family ATF, check the reservoir level regularly, and address leaks or abnormal steering symptoms promptly to keep the system functioning smoothly.
