Additional Notes

  • The Cadillac DeVille (USA / CAN) power steering system holds 0.7 liter across all listed configurations, covering both the DHS and DTS trims fitted with the 4.6 V8 32V engine.
  • A capacity of 0.7 liter is a relatively modest figure, consistent with the fluid volume held within a rack-and-pinion or recirculating-ball power steering reservoir and associated lines rather than a full hydraulic overhaul fill.
  • The 1999-2003 DeVille DHS 4.6 V8 32V and the 2003-2005 DeVille DHS 4.6 V8 32V share an identical 0.7 liter power steering capacity, indicating no change in system volume between the two production periods for the DHS trim.
  • The same consistency applies to the DTS trim, where both the 1999-2003 and 2003-2005 DeVille DTS 4.6 V8 32V specifications list 0.7 liter, confirming uniform capacity across the full span of years covered.
  • All four rows carry a normal use condition, meaning the listed 0.7 liter capacity applies under standard operating circumstances rather than a modified or severe-duty service scenario.
  • The 2003 model year appears as both an end point and a start point across the DHS and DTS rows, reflecting a mid-cycle boundary within the 1999-2005 generation rather than a separate model line.
