What type of power steering fluid for Ford?

Ford does not rely on a single universal power steering fluid. The correct type depends on your specific model and year. In practice, many older Ford vehicles used Dexron II/III- or Mercon-based ATFs in the power steering system, while newer models commonly call for Mercon V, Dexron VI, or Ford’s own Motorcraft Power Steering Fluid. Always check your owner's manual or the reservoir cap for the exact specification.


Ford's power steering fluid options


Understanding the options requires looking at the era of the vehicle. The following overview outlines common types used in Ford vehicles over the years.


Older Ford models (pre-2010)


In older Ford vehicles, the power steering system typically used standard automatic transmission fluids such as Dexron II/III or Mercon-based ATFs. Some early-era models may specify Mercon specifically.



  • Dexron II or Dexron III-based ATF in power steering systems

  • Mercon (Ford-brand) or Mercon V in certain models


Note: Always verify with the owner’s manual, as some models had unique specifications.


Modern Ford models (2010s and later)


In newer Ford vehicles, many systems specify Dexron VI or Mercon LV-based ATFs, and Ford’s own Motorcraft Power Steering Fluid is marketed as a dedicated PSF compatible with the various Dexron/Mercon families. Some models may still call for Mercon V depending on the exact system.



  • Dexron VI-based ATF for modern PSF on many vehicles

  • Mercon LV (low-viscosity) where specified

  • Mercon V in some mid-generation vehicles

  • Ford Motorcraft Power Steering Fluid (dedicated PSF product, designed for Ford systems)


These fluids are designed to work with Ford hydraulic power steering pumps and racks; always confirm the exact specification with your owner's manual.


How to determine the correct fluid for your Ford


Follow these steps to identify the proper PSF for your specific Ford model.



  1. Check the owner's manual or the label on the power steering reservoir cap for the exact specification (for example, Mercon V, Dexron VI, or Motorcraft PSF).

  2. Look for a cap label that explicitly states "Power Steering Fluid" and lists the compatible ATF family or Ford part number.

  3. Use Ford's official parts catalog or a dealership VIN lookup to confirm the recommended fluid for your exact VIN.

  4. If you must replace and the manual is unclear, consider using Ford Motorcraft Power Steering Fluid, which is designed for compatibility with Ford PS systems.

  5. Avoid mixing different PSF/ATF types. If you are changing fluid types, perform a full system flush and replace all old fluid.


Correct identification helps ensure proper performance and avoids pump wear or steering issues caused by incompatible fluids.


Maintenance tips and cautions


Keeping the power steering system healthy requires careful maintenance and awareness of fluid compatibility.



  • Never mix different power steering fluid types or transmission fluids unless the manufacturer explicitly allows it.

  • Consider a complete power steering fluid flush if you are changing to a different specification or if the fluid appears contaminated (burnt smell, unusually dark color, or debris).

  • Check fluid level with the engine off and cold, then follow the manual's guidance for hot-cold level differences if provided.

  • Inspect for leaks around the pump, hoses, and reservoir; leaks can degrade performance and damage the pump.

  • Listen for signs of trouble—whining noises, stiff or difficult steering, or reduced assist—which may indicate old or contaminated PSF or a failing pump.


Note: Some Ford models use electric power steering and do not rely on hydraulic PSF. This guidance applies to hydraulic systems still in use in many Ford vehicles.


Summary


The correct Ford power steering fluid depends on model year and vehicle specification. Older Fords commonly used Dexron II/III- or Mercon-based ATFs in the PS system, while newer models may require Mercon V, Dexron VI, or Ford’s Motorcraft Power Steering Fluid. Always verify with the owner's manual or reservoir labeling, and avoid mixing fluids. When in doubt, consult a Ford dealer or certified technician to ensure you choose the right fluid for your specific VIN and year.

Can I use Dot 3 for power steering?


Systems may not be compatible with brake fluid. This can lead to damage to seals and other components moreover brake fluid can react negatively with the paint. And other surfaces in your vehicle.



What kind of power steering fluid does Ford use?


The correct Ford power steering fluid type depends on the vehicle's model year, with most systems built between 1998 and 2012 requiring MERCON V, and those built after 2012 requiring MERCON LV. Always check your owner's manual or the power steering fluid cap to confirm the specific requirement for your vehicle, as some older models may use different fluids, such as ATF Type-F for systems before 1996-1998. 
By model year

  • 1998–2012: MERCON V
  • After 2012: MERCON LV
  • Before 1996–1998: Typically ATF Type-F 

Important considerations
  • Check your owner's manual: This is the most reliable way to determine the correct fluid type. 
  • Check the reservoir cap: The cap may have the required fluid type printed on it. 
  • Use the correct fluid: Using the wrong fluid can lead to poor performance and potential damage to the power steering system. 
  • Consider genuine products: For critical components like power steering, it is often recommended to use genuine Motorcraft fluids from a Ford dealership. 



Does it matter what type of power steering fluid I use?


Yes, it absolutely matters what type of power steering fluid you use, as the wrong type can cause damage to your car's steering system, including the pump and rack. Using the incorrect fluid can lead to issues like inconsistent steering assist, noise, and potential component failure. 
Why it's important to use the correct fluid

  • System damage: Power steering systems have tight tolerances and specific requirements for the fluid. The wrong fluid can cause seals to swell, damage the pump, or lead to rack and gearbox failure. 
  • Performance issues: The wrong fluid can affect how the system feels and performs, leading to inconsistent power assist or making the steering stiffer. 
  • Unique formulations: Many newer vehicles require a specific synthetic fluid, while others may use a specific type of automatic transmission fluid (ATF), such as Mercon V or Mercon LV. These have different chemical properties that are crucial for proper function. 

How to find the right fluid for your vehicle
  • Check the owner's manual: This is the most reliable source for your vehicle's specific fluid requirements. 
  • Look at the cap: The correct fluid type is often printed directly on the power steering reservoir cap. 
  • Consult service information: In some cases, you may need to consult a service manual for the exact specifications, especially for vehicles that use unique formulations. 



Can I use ATF in my Ford power steering?


Here. Pull the dipst stick out you can see how the fluid is red this is automatic transmission fluid. Says check with oil. Hot. Says use approved Ford fluid which in this case is ATF.
