The 2010 Ford Explorer uses Ford’s own Motorcraft Power Steering Fluid (PS Fluid) as the recommended fluid for its hydraulic power steering system.
For readers seeking context, the 2010 Explorer relies on a traditional hydraulic power steering system that relies on a dedicated fluid to keep the pump, seals, and rack functioning smoothly. Ford’s official guidance specifies Motorcraft PS Fluid as the preferred option, with substitutes sometimes considered in a pinch but not officially endorsed for long-term use. When in doubt, consult the owner’s manual or a Ford dealership for the exact specification.
Official fluid recommendation
Here is the fluid guidance most commonly cited by Ford for the 2010 Explorer. The primary choice is Motorcraft Power Steering Fluid.
- Motorcraft Power Steering Fluid (PS Fluid) — Ford’s recommended fluid designed specifically for Ford power steering systems.
Using the Ford-recommended PS Fluid helps maintain proper sealing, lubrication, and pump performance. If you cannot obtain Motorcraft PS Fluid locally, some technicians consider a Dexron II/III automatic transmission fluid as a temporary substitute, but you should verify compatibility and plan to revert to the Ford-spec fluid as soon as possible.
Substitutions and compatibility
When Motorcraft PS Fluid is not readily available, these notes apply to substitutes commonly discussed among technicians and owners. Always exercise caution and confirm with a professional if in doubt.
- Dexron II/III ATF — A commonly cited substitute for some Ford PS systems in the short term; compatibility can vary by vehicle and year, so verify and plan to switch back to Ford PS Fluid.
- Non-Ford universal power steering fluids — Some products are marketed as compatible with Ford PS systems, but they are not official Ford specifications. Use only if you confirm compatibility with your vehicle and are prepared for potential performance differences.
For best long-term results, Ford’s Motorcraft PS Fluid remains the recommended choice. If you are unsure, check the owner’s manual or contact a Ford dealership for the exact specification for your vehicle’s build date and regional availability.
How to check and refill
If you need to top off or replace the fluid, follow these practical steps to avoid air in the system and ensure proper operation.
- Park the car on level ground and apply the parking brake with the engine off.
- Open the hood and locate the power steering reservoir; remove the cap carefully and inspect the fluid level against the marked indicators.
- Clean the cap area, then slowly add Motorcraft Power Steering Fluid until the level reaches the “Full” mark. Do not overfill.
- Replace the cap, start the engine, and turn the steering wheel from lock to lock several times to bleed air from the system.
- Recheck the fluid level with the engine off and cooled; top up if necessary and inspect for any leaks around hoses and the pump.
Regularly monitoring the level and condition of the PS fluid helps maintain steering performance and prevents premature wear of the pump and seals.
Summary
For a 2010 Ford Explorer with its hydraulic power steering system, the recommended fluid is Ford Motorcraft Power Steering Fluid. Use the Ford-spec fluid for best performance and reliability. If you cannot find Motorcraft PS Fluid, a Dexron II/III ATF may be used only as a temporary substitute, but aim to revert to the Ford-spec fluid. Always consult the owner’s manual or a Ford dealer for the precise specification for your vehicle.
