Across the Ridgeline lineup, the answer depends on the model year. Pre-2017 Ridgelines use hydraulic power steering and typically require about 0.8–1.0 quart of fluid. Starting with the 2017 redesign, Honda moved to electric power steering, which does not use power steering fluid at all. Always confirm the exact capacity for your specific year in the owner's manual or service guide.
Hydraulic power steering (older Ridgelines, roughly 2006–2014)
For generations that still rely on hydraulic power steering, the system holds roughly a quart of fluid when fully filled. The following notes help clarify what to expect and how to handle top-offs or a basic flush.
- 2006–2014 Ridgeline models with hydraulic PS typically require about 0.8–1.0 quart (approximately 0.75–0.95 liters) to fill the reservoir from empty.
- A routine top-off or simple reservoir refill will generally use less than a full quart, depending on how much was consumed or lost since the last service.
- Always use the Honda power steering fluid specified for your vehicle (do not substitute ATF or other fluids). Check the owner’s manual for the exact fluid specification and grade.
In practice, capacity can vary slightly by year and by how the system is drained and bled during service. When performing a full flush or a complete replacement, plan to use about a quart (roughly 1 liter) of fluid to ensure the system is adequately filled and bled of air.
Electric power steering (newer Ridgelines, roughly 2017 and later)
Since the 2017 redesign, Honda Ridgelines use electric power steering (EPS). EPS systems do not use or require power steering fluid, and there is no reservoir to fill. If you notice steering issues, they are more likely related to the EPS control system, wiring, or related components rather than fluid leakage from a PS reservoir.
- There is no hydraulic power steering fluid capacity for models equipped with EPS; no fluid top-off is required.
- Maintenance focuses on electrical connections, the steering rack condition, belt drive (where applicable), and software/firmware updates as advised by Honda service.
If you have a 2017+ Ridgeline and encounter steering concerns, consult the owner's manual or a Honda dealer for EPS-specific diagnostics rather than attempting a fluid fill.
How to check or top off hydraulic power steering fluid (applicable to older Ridgelines)
Before performing any check or top-off, ensure the engine is cool and the vehicle is on level ground. Use the correct fluid type and follow the bleed procedure if you’ve performed a drain and fill.
- Locate the power steering fluid reservoir under the hood and pull the cap off carefully.
- Check the level against the “MIN” and “MAX” marks on the reservoir while the engine is off and the fluid is cold.
- Top off slowly with the recommended Honda PS fluid until the level sits between the marks. Do not overfill.
- Replace the cap securely and run the engine for a few minutes, turning the steering from lock to lock to bleed air from the system.
- Check for leaks and recheck the level once the engine has cooled again. Refill if necessary to bring it to the proper range.
Note: If the level repeatedly drops, there may be a leak in the PS line or rack that should be inspected by a qualified technician.
Summary
For the Honda Ridgeline, the required power steering fluid depends on the generation. Older, hydraulically powered models (roughly 2006–2014) use about 0.8–1.0 quart of Honda power steering fluid, with larger drops possible during a full system flush. The 2017 and newer Ridgelines use electric power steering, which requires no hydraulic fluid at all. Always refer to the owner’s manual for the exact specification and procedure for your specific year, and consult a dealer or certified technician if you have steering concerns.

The Worst Years for the Honda Ridgeline
If you're buying a Honda Ridgeline, these are the model years to avoid: 2006. 2007. 2008.
How to make a ridgeline faster?
Additional ways to make your Ridgeline faster and more capable include:
- Upgrading the exhaust system: Installing a performance exhaust can reduce back pressure and improve engine breathing.
- Cold air intake kits: These allow cooler, denser air into the engine, enhancing combustion efficiency.
