The 2010 Honda Accord with hydraulic power steering typically uses automatic transmission fluid that meets Dexron II/III specifications, or Honda’s own Power Steering Fluid (PSF) if your manual specifically calls for it. In practice, many Accords from this era operate with Dexron II/III ATF, but the exact requirement can vary by market and production date, so always verify with your owner's manual or a Honda dealer.
This article explains the fluid options, how to confirm the exact specification for your car, and practical steps for checking, topping up, or replacing the fluid.
Fluid options and compatibility
There are two main directions you may see in manuals or on labels for this model. Your exact requirement depends on the production date and market, so always check the owner's manual. The two common options are:
- Dexron II/III-compatible automatic transmission fluid (ATF) for the power steering system, which is widely used on many 2010 Accords with hydraulic PS.
- Honda Power Steering Fluid (PSF), brand-specific, used when the manual specifies PSF for your vehicle.
In practice, Dexron II/III ATF is the common go-to for most 2010 Accords; however, using Honda PSF where specified by the manual ensures compatibility with seals and pump materials.
How to Confirm the Correct Fluid
To confirm the exact requirement for your car, follow these steps:
- Consult the owner's manual section on Power Steering Fluid for the exact specification (ATF Dexron II/III vs. PSF).
- Check the power steering reservoir cap or inner label for the recommended fluid type or grade.
- Look for an under-hood sticker or VIN-specific service bulletin from Honda, as production changes can update the recommended fluid.
- When in doubt, contact a Honda dealership providing your VIN to get the precise specification for your car; do not mix fluids if the manual prohibits it.
Using the wrong fluid can cause seal damage, noise, and steering problems, so confirm before purchase or top-up.
Maintenance and care
Regular checks are part of routine maintenance. The power steering fluid should be clean and at the correct level, and you should avoid contamination from engine oil or coolant leaks.
Signs the power steering fluid needs attention
- Low fluid level in the reservoir
- Dark, burnt-smelling or contaminated fluid
- Whining or groaning noises from the power steering pump
- Stiff or "notchy" steering feel, especially at low speeds
These signs warrant inspection and possibly a fluid flush or top-up with the correct specification.
How to top up or replace the fluid
Here are the steps to top up or replace the power steering fluid safely:
- Park on level ground, engine off, and set the parking brake.
- Open the hood and locate the power steering fluid reservoir; check the fluid type and level using the dipstick or marks on the reservoir.
- If topping up, use the correct fluid and add small amounts at a time, rechecking the level until it reaches the Full mark. Do not overfill.
- If performing a replacement/flush: drain the old fluid from the reservoir or follow the factory procedure, then refill with the specified fluid.
- With the engine running, slowly turn the steering wheel from lock to lock several times to bleed air from the system, then recheck and top up if necessary.
- Inspect for leaks around the reservoir and hoses, then reinstall the cap.
Bleeding and replacement procedures can vary; if you’re unsure, have a technician perform the service to avoid air pockets and potential damage.
Summary
For a 2010 Honda Accord with hydraulic power steering, the recommended fluid is typically ATF Dexron II/III or Honda PSF, depending on your manual and production date. Always verify the exact specification in the owner’s manual or with a Honda dealer, use only the approved fluid, and follow proper bleeding procedures when servicing. Regular checks help prevent pump noise, seal wear, and steering issues, keeping the system responsive.
