Daihatsu Charmant
Coolant capacity & service interval
Daihatsu Charmant coolant capacity ranges from 5,9 to 7,1 liters. Service intervals occur every 40000 km or 48 months. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Daihatsu Charmant 1300 carries a cooling system capacity of 5.9 liters, which represents the total system fill volume including the radiator, engine block passages, and reservoir.
- The Charmant 1600 has a noticeably larger cooling system capacity of 7.1 liters, reflecting the greater displacement and associated thermal load of the larger engine compared to the 1300.
- The 7.1-liter capacity applies equally to both the 1981-1983 and 1983-1987 variants of the 1600, indicating no change in cooling system volume across the mid-production revision of that engine configuration.
- All three configurations share an identical service interval of 40,000 km or 48 months under normal use conditions, meaning the coolant change schedule is consistent regardless of engine size.
- The 48-month time limit on the coolant change interval reflects the degradation rate of coolant additives over time, which occurs independently of mileage accumulation.
- The normal use condition applied to all three rows means the stated intervals are not adjusted for demanding operating environments such as extreme temperatures or heavy towing cycles.
- The 1.2-liter difference in capacity between the 1300 and 1600 variants is a meaningful distinction when performing a full system drain and refill, as underfilling the 1600 by that margin could leave portions of the system without adequate coolant coverage.
