Additional Notes

  • The Maserati Quattroporte AM 107 carries a 2-liter power steering fluid capacity across all configurations, which is a relatively substantial reservoir volume for a hydraulic power steering system of the era and reflects the demands of a large, heavy luxury sedan.
  • Alongside the main power steering reservoir, a separate steering box capacity of 0.2 liter is specified for all configurations, indicating a recirculating ball or worm-type steering gear that holds its own lubricating fluid independently of the hydraulic assist circuit.
  • Both the power steering reservoir and the steering box share identical service intervals under normal use conditions: a fluid check at every 5,000 km and a full fluid change at every 20,000 km.
  • The 5,000 km check interval for the power steering fluid under normal use conditions suggests a relatively frequent monitoring schedule, consistent with maintenance practices common to high-performance European vehicles of the 1960s.
  • The 4200 and 4700 engine variants, spanning both the 1963-1967 and 1968-1970 production periods, share identical power steering and steering box capacities and service intervals, meaning the displacement difference between the two engines had no bearing on the steering system fluid specifications.
  • The continuity of the 2-liter power steering capacity and the 20,000 km change interval across the 1963-1967 and 1968-1970 model year splits indicates no revision to the steering system fluid service requirements between the two production phases of the AM 107.
