What kind of power steering fluid does a Ford Falcon take?
In most Ford Falcons with hydraulic power steering, the fluid is automatic transmission fluid (ATF), with Dexron II/III being the traditional standard. Some later models or regional variants may allow Dexron VI or Ford-approved equivalents. Always verify the exact specification in your owner's manual or on the reservoir label.
Understanding power steering fluid requirements
Power steering systems rely on ATF not only to lubricate moving parts but also to provide the hydraulic pressure that makes steering easier. The Falcon line covered a span of years and markets where the recommended ATF specification could shift. Using the wrong fluid can lead to reduced steering performance, noise, or wear, so identification of the correct specification for your exact year and market is important.
Because Ford’s documentation sometimes lists multiple compatible ATF grades or notes year-by-year changes, motorists are advised to confirm the precise spec for their exact vehicle. If in doubt, lean toward the more conservative option that matches Dexron II/III compatibility and avoid mixing incompatible fluids.
Common specifications by era
Below is a quick reference of the most commonly approved ATFs for Falcon power steering systems. The exact spec depends on model year and market, so use this as a guide and always verify with the manual or a Ford service source.
- Dexron II or Dexron III Automatic Transmission Fluid (ATF) — traditional specification used on many early and mid-generation Falcons
- Dexron VI ATF — newer specification that is backward-compatible with Dexron II/III in many Ford PS systems and often used as a modern replacement
- Mercon or Mercon V ATF — Ford’s older ATF families that are sometimes listed as acceptable alternatives in service notes
- Ford-approved power steering fluid (sometimes labeled specifically for Ford PS systems) — in some markets, the reservoir or manual may call for a Ford-branded or Ford-approved ATF
Concluding note: always confirm compatibility for your specific Falcon model and year, as the approved fluids can vary by market and production run.
How to verify the exact specification for your Falcon
To be sure you’re using the correct fluid, take these steps:
- Check the owner’s manual or the section dealing with lubricants and fluids for the exact ATF specification required for power steering
- Inspect the reservoir cap or nearby label, which often lists the accepted ATF grade (e.g., Dexron II/III or Dexron VI)
- Call a Ford dealer or authorized service center with your VIN to confirm the exact specification for your vehicle's year and market
- If you’re replacing fluid, ensure you don’t mix different ATF grades and follow the proper flushing or topping procedure recommended for your Falcon
Note: some later or specialty Falcons could move to electric power steering (EPAS) in specific markets or trims, in which case there is no hydraulic PS fluid to fill. When in doubt, rely on the manual or a certified technician.
When to change or top up power steering fluid
Power steering fluid should be checked regularly as part of routine maintenance. If you notice noise, hard steering, or fluid leaks, inspect the reservoir and piping for signs of contamination or loss. Use the specified ATF grade, top up to the marked level, and consider a professional flush if the fluid is dark, burnt-smelling, or contaminated.
Summary
Most Ford Falcons with hydraulic power steering use ATF, traditionally Dexron II/III, with Dexron VI increasingly used as a modern replacement. Always confirm the exact specification for your year and market from the owner’s manual or a Ford service source, and avoid mixing fluids. When in doubt, consult a qualified technician to ensure proper operation and longevity of the power steering system.
