Additional Notes
- The Soueast DX3 cooling system holds 6 liters of coolant across both the 1.5 and 1.5T engine variants, a capacity typical of compact crossover cooling systems where the fill volume reflects the total circuit including the engine block, radiator, and reservoir.
- Both the naturally aspirated 1.5 and the turbocharged 1.5T share an identical 6-liter cooling system capacity, indicating no meaningful difference in coolant circuit volume between the two engine configurations despite the added thermal load a turbocharger introduces.
- The coolant change interval for both variants is set at 40,000 km or 24 months under normal use conditions, meaning whichever threshold is reached first triggers the service requirement.
- A 24-month time limit alongside the 40,000 km distance interval reflects the chemical degradation of coolant additives over time, which occurs independently of mileage accumulation and is why both criteria apply simultaneously.
- The 40,000 km interval is relatively conservative compared to extended-life coolant schedules seen in some modern vehicles, placing the DX3 cooling service within a conventional maintenance cycle rather than a long-life fluid program.
