Datsun (Nissan) Sunny, B110/B210/B310

Coolant capacity & service interval

Datsun (Nissan) Sunny B110/B210/B310 uses coolant with a capacity range of 4,4 to 5 liters. Service intervals include 10000 km, 40000 km, and 40000 km/24 months. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Datsun (Nissan) Sunny 1000, B10 carries a cooling system capacity of 4.5 liters, paired with a change interval of 10,000 km under normal use conditions — a notably shorter interval compared to the later variants in the same model family.
  • The 1200, B110 (1970-1974) cooling system holds 4.9 liters, which is the largest single-figure capacity across all non-transmission-split configurations in the lineup.
  • The 120Y, B210 (1974-1977) has the smallest cooling system capacity of the group at 4.4 liters, while sharing the 40,000 km change interval introduced with the B110.
  • Both the 120Y and 140Y B310 variants (1977-1982) split cooling system capacity by transmission type: manual transmission fitments require 4.7 liters, while automatic transmission fitments require 5.0 liters. The difference reflects the additional heat load that automatic transmissions place on the cooling circuit in some configurations.
  • The 5.0-liter figure for automatic transmission B310 models represents the highest coolant capacity specified across all five configurations in the Sunny B110/B210/B310 range.
  • The B310-era change interval of 40,000 km is also expressed with a time-based limit of 24 months under normal use, meaning whichever threshold is reached first would govern the service point. No time-based limit appears in the earlier B10, B110, or B210 specifications.
  • The 120Y B310 and 140Y B310 share identical cooling system capacities and change intervals for both transmission types, indicating the 1.4-liter engine variant did not alter the cooling system volume or service schedule relative to the 1.2-liter variant in the same body generation.
