Nissan Sunny Wagon (EU)
Coolant capacity & service interval
Nissan Sunny Wagon (EU) coolant capacity ranges from 5,5 to 6,9 liters. Service intervals include checks at 30000 km or 12 months and changes at 60000 km or 24 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 Nissan Sunny Wagon (EU) 1.6 and 1.6 4x4 variants, both on the Y10 platform, share an identical cooling system capacity of 5.5 liters, indicating the all-wheel-drive drivetrain does not alter the thermal management volume of the engine cooling circuit.
- The 2.0 Diesel variant carries a notably larger cooling system capacity of 6.9 liters, which is 1.4 liters more than the 1.6 petrol configurations, reflecting the greater heat rejection demands typical of diesel combustion cycles.
- Under normal use conditions, the 1.6 and 1.6 4x4 models follow a two-stage service schedule: a coolant check at 30,000 km or 12 months, whichever comes first, followed by a full coolant change at 60,000 km or 24 months.
- The 2.0 Diesel specification lists only a change interval of 60,000 km or 24 months under normal use conditions, without a separate intermediate check interval as seen in the petrol variants.
- The 60,000 km or 24-month change interval is consistent across all three Y10 Sunny Wagon configurations for the 1990-1995 period, regardless of engine type or drivetrain layout.
- A 6.9-liter cooling system capacity, as seen in the 2.0 Diesel, represents a substantial fill volume and is relevant when calculating the quantity of coolant concentrate required to achieve a correct antifreeze-to-water ratio during a full system drain and refill.
