Mercury Mariner
Power steering fluid capacity & service interval
Mercury Mariner uses power steering fluid with a capacity of 1,9 liters. Service intervals occur every 15000 km or 12 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| Mariner 2.3 16V (2005-2008) |
|
| Mariner 3.0 V6 (2005-2008) |

Additional Notes
- The Mercury Mariner carries a power steering fluid capacity of 1.9 liters across both available engine configurations for the 2005-2008 model years.
- The 1.9-liter figure represents a system fill volume, reflecting the total fluid held within the power steering reservoir and associated hydraulic circuit rather than a partial service top-up amount.
- Both the 2.3 16V four-cylinder and the 3.0 V6 share an identical 1.9-liter capacity, meaning engine displacement and cylinder count produce no variation in power steering fluid volume between the two configurations.
- The specified service action for both engines is a fluid level check rather than a full drain-and-refill, which is a common distinction in power steering maintenance intervals.
- The check interval is set at 15,000 km or 12 months, whichever comes first, applying under normal use conditions for both the 2.3 16V and the 3.0 V6 variants.
- A 12-month time-based ceiling on the interval means the fluid level is to be inspected at least once per calendar year regardless of whether the distance threshold has been reached.
