Chevrolet typically uses Dexron VI-based power steering fluid for most of its hydraulic power steering systems, while electric power steering systems do not require any power steering fluid. Always verify the exact specification for your model and year in the owner's manual.
Understanding the fluid types Chevy uses by system
Chevrolet vehicles vary by year and drivetrain. In models with traditional hydraulic power steering, Dexron VI-based ATF is the standard fluid, and some older Chevys may have required earlier Dexron variants or GM’s own power steering fluid specification. Vehicles equipped with electric power steering do not use hydraulic power steering fluid at all. The best practice is to refer to the owner’s manual or GM service information for your exact vehicle.
To help you identify the right fluid, consider the following guidelines.
- Most modern Chevrolets with hydraulic power steering require Dexron VI-based power steering fluid (often supplied as GM Power Steering Fluid or Dexron VI-based PSF).
- Older Chevrolet models (before the mid-2000s) may have required Dexron II/III ATF or an older GM PS fluid specification; check the exact year/model manual for compatibility.
- Some newer Chevrolet models use electric power steering (EPS), which does not use any power steering fluid.
- When replacing PS fluid, use a GM-approved product or a Dexron VI-based ATF that meets GM specification; avoid fluids without explicit Dexron VI compatibility unless the manual allows them.
In short, the right fluid depends on your model and year. Always confirm with the owner's manual or a GM service bulletin to avoid compatibility issues that could damage the system.
How to verify the correct fluid for your Chevrolet
Follow these steps to confirm the exact specification for your vehicle, and to perform a replacement correctly.
- Check the owner's manual for the exact power steering fluid specification (Dexron VI-based PSF, Dexron II/III, or no PSF if EPS).
- Inspect the reservoir cap or label on the power steering fluid reservoir for the recommended fluid type (e.g., Dexron VI or GM Power Steering Fluid).
- If in doubt, contact a Chevrolet dealer or GM-certified technician with your vehicle identification number (VIN) to confirm compatibility.
- When changing fluid, use the recommended product and follow the bleeding procedure outlined in the manual to avoid air in the system.
If you need help, a dealer or qualified technician can quickly verify the exact specification for your car and perform any service safely.
Summary
Chevrolet’s typical hydraulic power steering fluid is Dexron VI-based ATF, aligned with GM’s specifications, while electric power steering systems use no fluid. Model-year and drivetrain variations mean you should always check the owner's manual or GM service information for your specific Chevy. Using the correct, GM-approved fluid helps maintain steering performance and protect the system.
