The 2010 Honda Civic with traditional hydraulic power steering uses Dexron II/III automatic transmission fluid (ATF) in the power steering system. If your Civic is equipped with electric power steering (EPS), there is no dedicated PS fluid to fill. Always consult the owner's manual for your specific trim and region, as equipment can vary.
System basics
In most 2010 Civics, the power steering system relies on hydraulic fluid that the pump circulates to assist steering. This fluid lubricates the pump, seals components, and transmits effort from the steering wheel to the steering rack. Some markets and trims may have variations or EPS, which uses an electric motor rather than hydraulic fluid.
Fluid options
When replacing or topping up the fluid, you’ll typically see two acceptable choices. The following options cover the standard hydraulic PS systems in this model year.
- Honda Power Steering Fluid (PSF) — the brand-approved option designed for Honda PS systems.
- Dexron II or Dexron III Automatic Transmission Fluid (ATF) — commonly used as a cross-reference in many Honda PS systems.
These options reflect typical guidance from owner manuals and service literature. In all cases, avoid engine oil, brake fluid, coolant, or water in the PS reservoir, as these can cause severe steering and component damage.
Replacing or topping up
Before you begin, confirm your Civic’s PS system type by checking the owner’s manual or the under-hood label. If you are topping up only, the procedure is straightforward; if you’re replacing the fluid, a careful bleed and level check ensures proper operation.
- Park the car on a level surface and set the parking brake.
- With the engine off, locate the power steering reservoir and remove the cap to check the level.
- If topping up, pour in small amounts at a time and recheck the level using the markings on the reservoir. Do not overfill.
- Start the engine, turn the steering wheel from lock to lock a few times, and let it run for a moment to circulate the fluid.
- Recheck the level and add more if necessary. Replace the cap securely.
Bleeding hydraulic PS is rarely needed on Civics, but if you’ve performed a full fluid replacement, you may need to cycle the steering and check for air pockets. If you notice noises, stiffness, or leaks, consult a technician.
EPS vs hydraulic: what to know
Most 2010 Civics use hydraulic PS with ATF; however, certain trims or regional versions might use electric power steering. EPS systems use an electric motor and do not require ATF. If your car's steering feels markedly different, check the service manual or sticker under the hood to confirm whether the system is EPS or hydraulic.
Bottom line
For a 2010 Honda Civic with hydraulic power steering, expect to use Dexron II/III ATF or Honda PSF as options. Always verify with the owner's manual or a dealer, especially if your vehicle was built for a market with electronic steering.
Summary
In short, the 2010 Honda Civic generally takes Dexron II/III automatic transmission fluid (ATF) in its hydraulic power steering system, with Honda PSF as an alternative. If your Civic uses electric steering, no PS fluid is required. When in doubt, consult the owner's manual and consider professional service for changes beyond topping up.
