Additional Notes
- The Jaguar XJ X350/X358 power steering system holds 1.6 liters of fluid across both the XJ8 4.2 and XJR 4.2 SC configurations for the 2004-2008 model years.
- A 1.6-liter capacity in a power steering system is a moderate reservoir volume, consistent with rack-and-pinion or recirculating ball systems found in full-size luxury sedans of the era.
- Both the naturally aspirated XJ8 4.2 and the supercharged XJR 4.2 SC share an identical 1.6-liter power steering fluid capacity, indicating no variation in reservoir size between the standard and performance variants.
- The capacity figure of 1.6 liters applies under normal use conditions for both configurations, meaning the specification reflects standard operating fill rather than a post-overhaul or dry-fill scenario.
