The answer depends on the model and year. Most modern Ford vehicles use a dedicated Motorcraft Power Steering Fluid, but some older or specialized models require Dexron-family ATF (such as Dexron VI) or Mercon LV. A few newer Fords with electric power steering may not need hydraulic fluid at all. Always verify with the owner's manual or the reservoir labeling for the exact specification.
Ford power steering fluid basics
Below are the common possibilities you may encounter across Ford vehicles. Fluid compatibility and exact specs can vary by year and model, so use this as a guide and confirm with the official manual or a dealer if you’re unsure.
- Motorcraft Power Steering Fluid — Ford’s dedicated PS fluid, recommended for many modern Ford models. This is the primary choice when the manual specifies a Ford PS fluid.
- Dexron VI ATF — A widespread automatic transmission fluid that is compatible with many Ford power steering systems built for Dexron VI specifications.
- Mercon LV — Ford’s low-viscosity ATF used in some newer PS systems; the reservoir or manual will indicate compatibility.
- Dexron II/III ATF — Older Ford power steering systems used these earlier Dexron formulations; newer manuals may note Dexron VI as the substitute.
- Electric power steering (EPS) systems — Do not require hydraulic power steering fluid; there is no fluid to add in the steering reservoir for these models.
In short, most current Ford vehicles rely on Motorcraft PS Fluid, but there is a spectrum of Dexron/Mercon formulations in use across different generations. Always verify for your specific vehicle.
How to determine the correct fluid for your Ford
Use these steps to confirm the exact specification for your car, truck, or SUV.
- Consult the owner’s manual for the exact power steering fluid specification and part number.
- Check the reservoir cap or the nearby label on the power steering reservoir for a fluids specification (e.g., “Motorcraft PS Fluid,” “Dexron VI,” or “Mercon LV”).
- If the manual is unavailable, use the VIN to query Ford’s official parts catalog or contact a dealership service department for the precise fluid type.
- Do not mix different fluid types. If a change is required, flush the system according to Ford’s service guidelines or have a trained technician perform the flush.
- For vehicles with electric power steering (EPS), verify that the system indeed uses hydraulic fluid; some models may have no regular PS fluid to add.
Following these steps will help ensure you use the correct Ford-approved fluid and maintain proper steering performance.
Model-year snapshots
Modern Ford vehicles (2010s–present)
Many newer Fords use Dexron VI or Mercon LV ATF in hydraulic power steering systems, with Motorcraft Power Steering Fluid as the manufacturer-recommended option where applicable. Always double-check the owner’s manual or reservoir labeling, as some models specify a Ford PS fluid while others align with a universal ATF category.
Older Ford vehicles (1990s–2000s)
Older Ford models commonly used Dexron II/III or Mercon V formulations in their power steering systems. Some of these may still accept Dexron VI as a substitute, but the manual will confirm the exact compatibility and any required service procedures.
Electric power steering models
Vehicles equipped with electric power steering typically do not require hydraulic PS fluid, though some may have a low-pressure reserve or related maintenance items. If in doubt, verify via the manual or a Ford service representative.
Summary
Ford’s power steering fluid requirements are not universal across all years and models. The safest approach is to consult the owner’s manual or the reservoir labeling to identify the exact specification—commonly Motorcraft Power Steering Fluid or a Dexron/Mercon ATF variant—and to avoid mixing fluids. For models with electric power steering, hydraulic PS fluid may not be required at all. When in doubt, contact a Ford dealer or trusted service professional to confirm the correct fluid for your vehicle.
