Additional Notes
- The INFINITI QX70 S51 power steering system holds 1 liter of fluid across all listed configurations, covering both the 3.7 and 5.0 engine variants in standard and AWD drivetrains.
- A 1-liter capacity is characteristic of a hydraulic power steering reservoir fill, representing the fluid volume held within the system rather than a full hydraulic pump or rack overhaul quantity.
- The 3.7-liter configurations, spanning 2013-2017 in both standard and AWD drivetrains, carry a specified check interval of every 10,000 miles or 12 months under normal use conditions.
- The 5.0-liter configurations, covering 2013-2014 in both standard and AWD drivetrains, share the same 1-liter capacity as the 3.7 but do not carry a listed check interval in the specifications.
- The 3.7 AWD and 3.7 non-AWD variants are identical in both capacity and check interval, indicating no differentiation in power steering fluid service requirements between the two drivetrain configurations for that engine.
- The same pattern applies to the 5.0 variants, where AWD and non-AWD configurations share an identical 1-liter capacity with no divergence between the two drivetrains.
- The 10,000-mile or 12-month check interval on the 3.7 configurations reflects a time-or-distance threshold, meaning whichever limit is reached first would apply under normal operating conditions.
