Daihatsu 850/1000
Coolant capacity & service interval
Daihatsu 850/1000 coolant capacity ranges from 2,8 to 4 liters. Service intervals occur every 40000 km or 48 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 Daihatsu 850/1000 coolant system capacity differs notably between the two engine variants. The 1000 (S/T 75) holds 4 liters, while the 850 (S/T 70) holds 2.8 liters, reflecting the difference in engine displacement between the two configurations.
- Both the 1000 (S/T 75) and the 850 (S/T 70) share an identical coolant change interval under normal use conditions, set at 40,000 km or 48 months, whichever comes first.
- The 48-month interval tied to normal use means coolant replacement is due at least every four years regardless of mileage accumulation, since the time-based threshold can be reached before the distance-based one in low-usage scenarios.
- The 1000 (S/T 75) covers the 1984-1992 model years, while the 850 (S/T 70) spans 1983-1986, meaning the two variants overlapped in production for a period of three years from 1984 to 1986.
- A 4-liter cooling system capacity in the 1000 (S/T 75) is consistent with a small-displacement engine where the system volume is modest but sufficient to maintain thermal regulation across the specified service interval.
- The 2.8-liter capacity of the 850 (S/T 70) cooling system is among the smaller values typical of subcompact or kei-class vehicles, where reduced engine bay volume directly limits the total coolant circuit size.
