Nissan Q-bic (EU)
Coolant capacity & service interval
Nissan Q-bic (EU) coolant capacity ranges from 5,5 to 6,5 liters. Service intervals occur every 90000 km or 36 months. The data covers 3 configurations.

Additional Notes
- The Nissan Q-bic (EU) 1.6 and 1.6i variants, both on the Y10 platform from 1992-1996, share an identical cooling system capacity of 5.5 liters, indicating no difference in coolant fill volume between the carbureted and fuel-injected petrol configurations.
- The 1.7 D diesel variant carries a cooling system capacity of 6.5 liters, which is one full liter more than either petrol variant, a difference consistent with the higher thermal load diesel engines typically generate and the additional cooling demands of compression ignition combustion.
- All three variants specify a change interval of 90,000 km or 36 months under normal use conditions, meaning the distance and time limits run concurrently, with whichever threshold is reached first serving as the service trigger.
- The 36-month time limit on the coolant change interval reflects the chemical degradation of antifreeze additives over time, which occurs regardless of mileage accumulation, making the calendar component of the interval independently significant.
- The 90,000 km distance interval is notably long for a coolant service specification from the early 1990s, placing the change interval in a range associated with extended-life coolant formulations rather than conventional short-interval antifreeze products of that era.
- The capacity figures of 5.5 and 6.5 liters represent full cooling system fills, encompassing the radiator, engine block passages, heater core circuit, and overflow reservoir, rather than a partial drain-and-refill volume.
