Ferrari 400

Power steering fluid capacity & service interval

Ferrari 400 power steering fluid capacity ranges from 1 to 2,8 liters. Service intervals include 10000 km for checks and 12 months for changes. The data covers 3 configurations.

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

Additional Notes

  • The Ferrari 400 GT (1976-1979) and 400 GTi (1979-1985) both carry a 1-liter power steering fluid capacity, which represents a standard service fill for a conventional hydraulic rack-and-pinion or recirculating ball steering system of that era.
  • The 400 GTi equipped with the combined power steering and hydraulic levelling system holds a notably larger 2.8-liter capacity, reflecting the additional fluid volume required to serve both the steering circuit and the self-levelling suspension circuit simultaneously.
  • Across both the 400 GT and the standard 400 GTi configurations, the specified check interval falls at every 10,000 km under normal use conditions.
  • The change interval for power steering fluid on both the 400 GT and the standard 400 GTi is set at 12 months under normal use conditions, meaning the replacement schedule is time-based rather than mileage-based.
  • No capacity-only entry exists for the 400 GT, whereas the 400 GTi appears in two distinct configurations: one with a standalone power steering system and one with the combined power steering and hydraulic levelling system, each carrying a different fluid capacity.
