The 2003 Ford Escape uses automatic transmission fluid (ATF) in its power steering system—Dexron II/III or Mercon ATF is suitable.
In the 2003 Escape, the hydraulic power steering system relies on ATF rather than a dedicated power steering fluid. Ford’s manuals from that era commonly list Dexron II or Dexron III (and Mercon) as acceptable ATF specs for the PS reservoir. Today, the recommended practice is to use a conventional ATF that matches those specifications, or a Ford-branded power steering fluid that states compatibility with Dexron/Mercon ATF.
Compatible ATF options
The following ATF specifications are considered acceptable for the 2003 Escape power steering system. Use a clean, specification-matched fluid and avoid mixing different types.
- Dexron II ATF
- Dexron III ATF
- Mercon ATF (Ford's older specification)
Note: Dexron II/III and Mercon ATFs are generally cross-compatible for Ford power steering systems from this era. If you can only source newer Dexron VI, verify with a dealer or service bulletin whether it is compatible with your exact engine and steering rack.
How to check and maintain
Regular checks help ensure the power steering remains responsive. Follow these steps to inspect and top up the fluid if needed.
- Locate the power steering reservoir under the hood and inspect the fluid level against the marks on the cap or reservoir.
- With the engine off, add the appropriate ATF until the level reaches the full line; if you have just started the car and feel steering play or noise, you may need a bleed procedure or service.
- If the fluid is dark, gritty, or has a burnt odor, consider a flush and replacing all PS fluid to prevent damage to the pump.
- Seek professional service if you notice leaks, whining noises, or stiff steering that persists after topping up.
Maintaining clean, specification-matched ATF helps preserve steering feel and prevents wear in the hydraulic system.
Summary
For a 2003 Ford Escape, power steering uses ATF in the reservoir, with Dexron II, Dexron III, or Mercon ATFs being acceptable options. Use a clean, specification-matched fluid and avoid mixing fluids. Regular checks and prompt attention to leaks or abnormal sounds help maintain steering performance and prevent damage to the pump and rack.
