Fiat Duna, 146 (EU)
Coolant capacity & service interval
Fiat Duna and 146 (EU) models require 6 liters of coolant. The service interval for coolant is 60000 km or 24 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Fiat Duna 60 and Weekend 60, covering 1986-1992, share a cooling system capacity of 6 liters, which represents the total system fill volume including the radiator, hoses, and reservoir.
- The Duna 70 and Weekend 70, introduced a year later in 1987 and running through 1992, carry the same 6-liter cooling system capacity as the 60-series variants.
- Both the 60-series and 70-series configurations specify a coolant change interval of 60,000 km or 24 months under normal use conditions, whichever comes first.
- A 24-month time-based interval alongside the 60,000 km distance limit means a vehicle accumulating low annual mileage would still require a coolant change within two years under normal use.
- The alignment of capacity and interval figures across both the 60 and 70 engine variants suggests a shared cooling system architecture between the two configurations despite the difference in engine output designation.
