Additional Notes

  • The Volvo 66 (EU) power steering system is built around a steering box design across all four trims, rather than a rack-and-pinion arrangement, which is consistent with the compact European vehicle architecture of the mid-1970s.
  • A capacity of 0.04 liter is an exceptionally small fluid volume, reflecting the self-contained nature of a steering box unit where fluid is retained within the housing itself rather than circulated through a reservoir-and-pump circuit.
  • All four trims — the 66 L, 66 DL, 66 GL, and 66 GLS Combi — share an identical capacity of 0.04 liter, indicating no variation in steering box size or fluid volume across the trim lineup.
  • The check interval is set at 10,000 km under normal use conditions for every listed trim, meaning the interval specification applies uniformly regardless of trim level.
  • The 66 GLS Combi carries a narrower model year span of 1977-1978, compared to the 1975-1978 range of the L, DL, and GL trims, though the steering box capacity and check interval remain identical to the other trims.
