Additional Notes
- Both the Chang'an Reaton / Ruicheng 1.8T and 2.0 engine variants, each under the SC7186 body designation starting from 2013, share an identical cooling system capacity of 7.8 liters, indicating a uniform cooling circuit volume across the two engine configurations.
- A 7.8-liter coolant capacity falls within the range typical of passenger car cooling systems, reflecting a moderately sized circuit that accounts for the engine block, cylinder head passages, radiator, heater core, and associated hoses.
- The check interval for the cooling system is specified at 10,000 km or 6 months under normal use conditions, whichever comes first, applying equally to both the 1.8T and 2.0 engine variants.
- The coolant change interval is set at 20,000 km or 12 months under normal use conditions, representing a relatively short drain period compared to extended-life coolant schedules seen in some other manufacturers' specifications.
- The check interval of 10,000 km or 6 months is exactly half the change interval of 20,000 km or 12 months, meaning one intermediate inspection falls between each full coolant replacement cycle for both engine variants.
