Additional Notes

  • The Cadillac Eldorado (1957-1958) rear differential carries a capacity of 2.35 liters, and the check interval is set at 3,000 km under normal use conditions.
  • Starting with the 1959-1960 model years, the rear differential capacity increased slightly to 2.4 liters, while the check interval extended to 6,000 km, a figure that remained consistent through the 1961-1963 rear differential specification as well.
  • The 1959-1963 rear differential configurations share identical capacity and check interval values at 2.4 liters and 6,000 km respectively, reflecting no change across those five model years.
  • Beginning with the 1968-1969 model years, the Cadillac Eldorado transitioned from a rear differential to a front differential arrangement, with a capacity of 2.1 liters under normal use conditions.
  • The 1968-1969 front differential and the 1968-1969 front limited slip differential share the same 2.1-liter capacity, with both carrying a check interval expressed in time rather than distance, specifically every 6 months.
  • A limited slip differential variant was listed alongside the standard front differential for both the 1968-1969 and 1970-1975 configurations, each sharing the same capacity as the non-limited slip counterpart for the respective period.
  • For the 1970-1975 model years, the front differential capacity decreased to 1.9 liters compared to the 2.1 liters specified for 1968-1969, while the 6-month check interval remained unchanged across both the standard and limited slip variants.
  • The shift from distance-based intervals in the 1957-1963 rear differential specifications to a time-based interval of 6 months in the 1968-1975 front differential specifications represents a structural difference in how service checks are expressed across the two eras covered by the data.
