Ferrari 365

Power steering fluid capacity & service interval

Ferrari 365 requires power steering fluid with a capacity range of 0,2 to 1 liter. Service intervals include checks at 5000 km and 10000 km, with a fluid change at 20000 km. The data covers 4 configurations.

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

Additional Notes

  • The Ferrari 365 GT 2+2, 365 GT4/2+2, and 365 GTC/4 all share a power steering fluid capacity of 1 liter, which is a typical reservoir fill volume for hydraulic power steering systems of that era.
  • All three power steering configurations carry a check interval of every 5,000 km under normal use conditions, with no separate change interval listed in the specifications.
  • The 365 GT4 BB (Berlinetta Boxer) uses a steering box rather than a hydraulic power steering system, and its fluid capacity of 0.2 liters reflects the much smaller volume associated with manual steering box lubrication.
  • The steering box on the 365 GT4 BB carries a check interval of 10,000 km under normal use, which is double the 5,000 km check interval applied to the power steering systems across the other 365 variants.
  • A change interval of 20,000 km is specified for the 365 GT4 BB steering box fluid under normal use conditions, a service action that does not appear in the specifications for the power steering systems on the other models.
  • The 0.2-liter capacity of the 365 GT4 BB steering box stands in notable contrast to the 1-liter capacity of the hydraulic power steering reservoirs, reflecting the fundamental difference between a sealed gear lubricant fill and a pressurized fluid circuit.
