Nissan Altima, L31 (USA / CAN)

Power steering fluid capacity & service interval

Nissan Altima, L31 (USA / CAN) uses power steering fluid with a capacity of 1 liter. Service intervals consist of checks every 15000 miles or 12 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Altima 2.5 (USA) (2002-2006)
  • Use: Normal
  • Capacity 1 liter
  • Check 15000 miles/ 12 months
Altima 3.5 (USA) (2002-2006)
  • Use: Normal
  • Capacity 1 liter
  • Check 15000 miles/ 12 months

Additional Notes

  • Both the 2.5-liter and 3.5-liter engine configurations of the Nissan Altima L31 (USA) share an identical power steering fluid capacity of 1 liter, covering the 2002-2006 model years.
  • A 1-liter capacity is characteristic of a reservoir service fill rather than a full system overhaul, reflecting the volume needed to maintain proper fluid level during routine maintenance rather than a complete drain-and-refill procedure.
  • The specified check interval for power steering fluid is every 15,000 miles or 12 months, whichever comes first, applied under normal use conditions for both engine variants.
  • The 15,000-mile or 12-month check interval is a fluid inspection interval, not necessarily a full fluid replacement interval, meaning the service action at that point is to verify fluid condition and level rather than automatically exchange the fluid.
  • The alignment of specifications across the 2.5-liter and 3.5-liter variants suggests the power steering system architecture does not differ in reservoir capacity between the two engine families in the L31 generation.
