Additional Notes
- The Chery QQ6 / S21 1.1 carries a cooling system capacity of 6 liters, while the 1.3 engine variant holds 6.5 liters, reflecting the larger displacement's greater thermal mass and additional coolant volume needed to regulate engine temperature.
- Both the 1.1 and 1.3 engine variants share an identical service interval of 40,000 km or 48 months under normal use conditions, meaning whichever threshold arrives first would trigger a coolant change.
- The 48-month time limit on the coolant change interval is significant because coolant additives degrade over time regardless of mileage, so a vehicle driven infrequently could still reach the time-based threshold before the distance-based one.
- The normal use condition applied to both variants indicates the 40,000 km / 48-month interval is not adjusted for demanding operating environments, and both rows carry no separate severe-use interval specification.
- The 0.5-liter difference in cooling system capacity between the 1.1 and 1.3 variants means a technician performing a full coolant service on the larger engine would need to account for the additional volume to avoid underfilling the system.
