The 2012 Chevrolet Impala uses a hydraulic power steering system that GM specifies Dexron VI automatic transmission fluid as the proper fluid. Using the correct fluid helps protect the pump and steering components. If you’re unsure, check the under-hood label on the power steering reservoir or consult the owner's manual or a GM dealer.
What fluid does the 2012 Impala use?
For most GM vehicles of this era, the power steering system is designed to use Dexron VI ATF as the power steering fluid. Dexron VI is a newer specification that supersedes older Dexron II/III formulations and is generally compatible with the hydraulic steering components. Always verify the exact specification for your VIN by checking the reservoir cap, the under-hood label, or the GM service documentation for your vehicle.
The following options are commonly considered acceptable, but you should confirm with your manual or dealer if you’re unsure:
- Dexron VI automatic transmission fluid (ATF) used as the power steering fluid.
- GM Power Steering Fluid (PSF) that is formulated to meet Dexron VI compatibility.
- Avoid using motor oil, brake fluid, or non-specified fluids in the power steering reservoir, and do not mix Dexron II/III with Dexron VI unless a professional confirms it is safe to do so.
In short, use Dexron VI ATF (or a GM PSF product specified as Dexron VI compatible) for the 2012 Impala, and follow the vehicle’s service intervals or any fluid-change indications from GM.
How to check and maintain the fluid
Keeping the power steering fluid at the correct level and in good condition helps maintain steering performance and pump longevity. The steps below describe a standard approach, but always follow your owner's manual for model-specific guidance.
- Park on level ground with the engine off and cold. Locate the power steering reservoir, then clean the cap area to prevent dirt from entering.
- Remove the cap and check the fluid level against the marks on the reservoir (often marked HOT/ COLD or MIN/MAX). If the level is below the minimum, add Dexron VI ATF a little at a time until it reaches the proper level.
- Use only Dexron VI ATF or GM PSF that specifies Dexron VI compatibility. Do not mix with other transmission fluids unless advised by a professional.
- After topping up, replace the cap and start the engine. With the engine running, gently turn the steering wheel from lock to lock a few times to bleed air from the system.
- Check again for proper level and inspect for leaks around hoses, the pump, and the reservoir. Top up if necessary and wipe away any spills.
- If you notice unusual noises, foaming fluid, a persistent low level, or leaks, have the steering system inspected by a qualified technician.
Regularly checking and using the correct Dexron VI fluid helps keep the power steering system quiet and responsive. If you experience steering whine, roughness, or difficulty turning, low fluid or a component failure could be the cause.
Summary
The 2012 Chevy Impala’s hydraulic power steering system is designed to use Dexron VI automatic transmission fluid (ATF) or GM PSF that is Dexron VI compatible. Always verify the exact specification for your vehicle, avoid mixing fluids, and follow proper top-up and bleeding procedures to maintain steering performance. If in doubt, consult the owner's manual or a GM-certified technician.
