Fiat 132 (EU)

Additional Notes

• The Fiat 132 rear differential fluid capacity changed across production phases, with three distinct values appearing in the specifications: 1.43 liters for the earliest configurations, 1.65 liters for the mid-period units, and 1.28 liters for the later ones. These differences reflect changes in the rear axle assembly rather than engine displacement, since both the 1.6 and 1.8 variants share the same capacity figure within each overlapping production period.
• The 1972-1974 configurations of the 132 1.6 (132A) and 132 1.8 (132A1) both carry a rear differential fluid capacity of 1.43 liters. A shared capacity across two different engine variants in the same period points to a common rear axle unit used regardless of the engine fitted.
• For the 1974-1977 period, both the 132 1.6 (132A) and 132 1.8 (132A) share a rear differential capacity of 1.65 liters, the highest value across all listed configurations. This increase from the earlier 1.43-liter figure suggests a revised or larger differential housing was adopted during this phase.
• The 1977-1981 configurations across all listed variants, including the 132 1.6 (132A) and 132 2.0 (132A2), carry the lowest differential capacity in the specifications at 1.28 liters. This reduction from the 1.65-liter mid-period figure indicates another change in the rear axle design for the final production phase.
• Limited slip differential variants for both the 132 1.6 (132A) and 132 2.0 (132A2) in the 1977-1981 period share the same 1.28-liter capacity as their open differential counterparts. While limited slip units typically require a specific fluid type or additive, the capacity itself is identical to the standard rear differential in these specifications.
• All configurations across the full 1972-1981 span share a uniform check interval of 10,000 km and a change interval of 30,000 km under normal use conditions. The consistency of these intervals across all engine variants and differential types indicates a single service schedule applied to the rear differential throughout the model's production life.
• The 30,000 km change interval listed for all configurations represents a relatively extended drain period for a rear differential, reflecting the lower operating stress of a passenger car axle compared to heavier commercial applications. The 10,000 km check interval, set at one-third of the change interval, allows for fluid level and condition monitoring between full service events.
