Additional Notes
- Across all Fiat Fullback 2.4 D configurations from 2016-2020, the rear differential fluid capacity is specified at 2.3 liters, whether the unit is a standard open differential or a limited slip differential.
- The front limited slip differential on the 4WD variants holds a notably smaller 1.2 liters of fluid, reflecting the physically smaller housing of a front axle differential compared to the rear unit.
- Both the 113 kW and 133 kW 4WD variants share identical front limited slip differential capacity and service intervals, meaning the power output difference between the two engine tunes has no bearing on differential fluid specifications.
- Under normal use conditions, all differential positions across the 2016-2020 Fullback range follow a check interval of every 20,000 km or 12 months, whichever comes first.
- The fluid change interval for all differentials in the Fullback 2.4 D lineup is set at 80,000 km or 48 months under normal use conditions, placing a full drain-and-refill cycle at four times the frequency of a routine level check.
- The 2WD Fullback 2.4 D (113 kW) carries specifications for both a standard rear differential and a rear limited slip differential, with both sharing the same 2.3-liter capacity and identical service intervals, indicating the limited slip unit does not require more frequent servicing under normal conditions.
