Additional Notes
- The DAF F800 CB (4x2) and F800 CN (4x2) both carry a coolant system capacity of 25 liters, which is a figure associated with a full system fill encompassing the engine block, radiator, and expansion reservoir.
- A 25-liter capacity in a commercial vehicle cooling system of this era reflects the demands of sustained heavy-duty operation, where larger fluid volumes help maintain stable thermal regulation across extended running periods.
- The change interval for both configurations is set at 24 months under normal use conditions, placing coolant renewal on a two-year cycle rather than a mileage-based schedule.
- A time-based interval of 24 months is characteristic of coolant service schedules because coolant degradation is driven largely by chemical breakdown and corrosion inhibitor depletion over time, independent of distance traveled.
- The CB and CN body variants share identical capacity and interval specifications across the full 1987-1991 model year span, indicating no differentiation in cooling system design between those two configurations.
