The answer depends on your specific Hyundai model and year. Many older Hyundai models with hydraulic power steering use ATF from the Dexron family, while many newer Hyundai cars rely on electric power steering that does not require any power steering fluid at all. Always check the owner's manual or ask a Hyundai dealer for your VIN to confirm the exact specification.
This article explains the difference between hydraulic and electric power steering in Hyundai vehicles, how to identify which system your car has, and the fluid implications for maintenance and top-ups. It provides practical guidance based on common industry practice and Hyundai documentation.
Hydraulic versus electric power steering in Hyundai vehicles
Before we dive into specifics, it helps to understand the two main types of Hyundai steering systems and how they affect fluid use and maintenance.
Hydraulic power steering (PS)
Some older Hyundai models use a hydraulic power steering system that relies on a dedicated steering fluid, typically an ATF-based fluid from the Dexron family. The exact specification can vary by model and production year, so identifying the correct fluid is important to avoid damage.
Informative note: If your Hyundai has a power steering reservoir labeled “Power Steering Fluid,” it is likely a hydraulic system and will require a Dexron-family ATF or a Hyundai-recommended equivalent as per the manual.
- Dexron-based ATF is commonly used in hydraulic PS systems (older Dexron II/III formulations; newer systems may specify Dexron VI).
- Always use the exact specification listed in your owner's manual or Hyundai service information; fluids are not universally interchangeable.
- Avoid mixing different ATF specifications in the hydraulic PS circuit, as this can degrade performance and potentially cause damage.
Concluding for hydraulic PS: If your Hyundai uses hydraulic power steering, the typical fluid is a Dexron-family ATF, with Dexron VI becoming common in newer hydraulic systems. Always verify with the official manual or dealer for your model and year.
Electric power steering (EPS)
Many modern Hyundai passenger cars use electric power steering, which does not require a dedicated power steering fluid. In EPS systems, the steering is managed by an electric motor controlled by a steering software module, and there is no reservoir or fluid to top up for PS function.
Concluding for EPS: If your Hyundai has EPS, there is no power steering fluid to purchase or replace. Maintenance centers focus on software updates, belt integrity, battery health, and electrical connections rather than fluid changes.
How to determine which system your Hyundai has
To avoid guesswork, use these checks to confirm your system type and, if applicable, the correct fluid specification.
- Consult the owner’s manual or Hyundai’s official service information for your exact model and year.
- Look under the hood for a power steering reservoir and cap. A reservoir labeled “Power Steering Fluid” usually indicates hydraulic PS; no reservoir or an EPS indication suggests an electric system.
- Note that many Hyundai passenger models from the mid-2010s onward use EPS; verify with the VIN if in doubt.
- If in doubt, contact a Hyundai dealer or certified technician with your vehicle identification number (VIN) for the precise specification.
Concluding: The system type and fluid needs depend on the model and year. Use the official documentation or a dealer confirmation to ensure you use the correct fluid (if any) for your car.
Summary
Hyundai vehicles span hydraulic and electric power steering systems. Hydraulic PS typically requires a Dexron-family ATF (with Dexron VI common in newer hydraulic systems), while electric power steering does not use a dedicated PS fluid. Always verify the exact specification for your model and year in the owner's manual or with a Hyundai dealer using your VIN, and never mix different ATF specifications in a hydraulic PS system.
