Ford predominantly uses Motorcraft Power Steering Fluid (PSF) for its hydraulic power steering systems; however, the exact specification can vary by model and year. In many newer vehicles with electric power steering, no hydraulic PSF is required. Always check the owner's manual or the reservoir cap for the precise fluid specification.
Understanding Ford's fluid landscape
The fluid a Ford vehicle uses depends on whether the car has hydraulic or electric power steering, and on model-year specifics. Ford’s official guidance generally points to Motorcraft PSF for hydraulic systems, while newer models with electric power steering operate without PSF. The owner's manual and the reservoir label are the authoritative sources.
Hydraulic power steering systems: the typical fluid
Before listing the common options, note that these apply to vehicles with a hydraulic power steering pump and rack.
- Motorcraft Power Steering Fluid (PSF): Ford’s recommended PSF for most hydraulic PS systems. It is sold under the Motorcraft brand and designed for Ford steering components.
- ATF-based fluids in older Ford PS systems: Some older Ford models used automatic transmission fluid in the power steering system. If your vehicle falls into an older category, do not substitute fluids without confirming the exact specification from the manual or dealer.
Concluding: For most modern Fords with hydraulic power steering, Motorcraft PSF is the standard choice; older models may require ATF, so always verify the specification for your vehicle.
Electric power steering (EPS) and its implications
Many newer Ford vehicles use electric power steering, which does not rely on hydraulic fluid and therefore does not require PSF. In these vehicles, there is no power steering fluid in the system. If you’re working on an older model or a vehicle with a mixed system, confirm the correct fluid with the documentation.
How to confirm the right fluid for your specific Ford
To avoid mistakes, use the following steps to verify the correct power steering fluid for your car, truck, or SUV.
- Check the owner’s manual: Look up "power steering fluid" or "PSF" and note the exact specification or part number.
- Inspect the reservoir label: Some reservoirs specify the recommended fluid type or part number (for example, Motorcraft PSF).
- Consult a dealer or trusted repair shop: Provide your vehicle identification number (VIN) to ensure you get the precise fluid for your model year and trim.
Concluding: The manual and reservoir labeling are your best sources of truth; if in doubt, contact Ford or a dealership for the exact PSF specification.
Summary
In short, Ford’s hydraulic power steering systems typically use Motorcraft Power Steering Fluid (PSF). Some older or specialty models may require ATF, and many newer vehicles employ electric power steering that does not require PSF at all. Always verify the correct fluid for your specific vehicle via the owner’s manual, reservoir cap, or a Ford dealer to ensure you use the proper specification.
What type of ATF does Ford use?
Mercon represents a series of technical standards for automatic transmission fluid, developed and trademarked by Ford Motor Company. This designation serves as a mark of quality that Ford has established for fluids used in automatic transmissions.
What is special about Mercon V?
MAG 1 MERCON® V ATF protects against wear and transmission shudder, resists thickening to high temperatures, and provides friction stability to maintain smooth consistent shift performance.
What power steering fluid does Ford recommend?
Note: All power steering systems built between 1998 and 2012 require the user of MERCON® V fluid. Power steering systems build after 2012 require MERCON® LV. Refer to Workshop Manual or Owner's Guide.
