In most 2010 Ford F-150 models, the power steering system uses an ATF-based fluid. The two fluids most commonly approved are Motorcraft Mercon V ATF and Dexron VI ATF, but you should confirm the exact specification from your owner’s manual or the reservoir cap for your specific vehicle.
What the manual generally indicates
Ford’s service guidelines for the 2010 F-150 place the power steering fluid in the ATF family, with Mercon V and Dexron VI being the most widely accepted options. Because production years, engine options, and individual vehicles can vary, the definitive specification is printed on your vehicle’s manual or on the reservoir cap.
- Motorcraft Mercon V Automatic Transmission Fluid (ATF) – Ford’s traditional specification for many power steering systems from this era.
- Dexron VI Automatic Transmission Fluid – a newer ATF that is widely compatible with Ford power steering systems when approved by the manual or reservoir labeling.
Before the list: The following fluids are commonly considered acceptable for many 2010 F-150 power steering systems when used according to the manufacturer’s instructions.
Conclusion after the list: Use only fluids that meet Ford’s specifications for your truck, and avoid mixing fluids that do not carry an approved Mercon V or Dexron VI designation for your model year.
How to verify the exact specification for your truck
To avoid guessing, verify the correct fluid for your particular F-150 using several quick checks and resources.
- Check the owner’s manual: Look under Fluids/Specifications for the exact power steering fluid designation (Mercon V, Dexron VI, or another specification).
- Inspect the power steering reservoir cap: Some caps include the required ATF specification or wording like “Use Mercon V” or a Dexron designation.
- Look for a label under the hood or on the radiator support: Some vehicles have a sticker listing recommended fluids by system.
- If in doubt, contact a Ford dealership or consult Ford’s official service data with your VIN to confirm the exact spec for your truck’s production date and engine.
Conclusion after the list: Verifying the exact specification protects against using the wrong fluid, which can damage the pump and steering gear. Always match the fluid to the official specification for your exact vehicle.
Additional guidance and best practices
When topping up or flushing the power steering system, follow these best practices to maintain performance and longevity.
- Do not mix different ATF types. If you’re unsure of the current fluid’s type, consider a system flush and fill with the correct specification.
- Replace the fluid at intervals recommended by Ford or when diagnosing steering issues such as noise, stiffness, or leaks.
- Use only the exact specification approved for your vehicle; if your manual lists Mercon V, use Mercon V rather than Dexron VI, unless the service data confirms compatibility.
Conclusion after the list: Adhering to the correct ATF specification helps ensure smooth steering operation and prevents wear on the power steering pump and hoses.
Summary
The 2010 Ford F-150 generally uses an ATF-based power steering fluid, with Motorcraft Mercon V and Dexron VI as the most commonly accepted options. Always verify the exact specification for your specific vehicle by checking the owner’s manual, the reservoir cap, or a Ford service source using your VIN. When in doubt, use the Ford-approved Mercon V ATF or Dexron VI ATF that matches the official specification, and avoid mixing fluids or using non-ATF substitutes. Regular checks and replacements according to Ford’s guidelines help keep the steering system reliable.
