Additional Notes
- The Acura Integra DE4 cooling system service intervals across all listed configurations follow a flexible schedule governed by the on-board maintenance system rather than a fixed mileage or time-based interval.
- The 1.5T engine, available in both CAN and USA markets from 2022, carries a service fill capacity of 5.6–5.8 liters, reflecting the range of coolant volume expected when refilling the system during routine maintenance without a full drain.
- No overhaul capacity figure is listed for the 1.5T configuration, meaning only the service fill value of 5.6–5.8 liters is specified for that engine.
- The Integra 2.0 Type S, introduced in 2023 for both CAN and USA markets, has a notably higher service fill capacity of 6.7 liters compared to the 1.5T, indicating a larger cooling system volume consistent with the more powerful engine.
- An overhaul capacity of 8.3 liters is specified for the 2.0 Type S, representing the total system volume when the cooling circuit is fully drained and refilled, such as during a complete coolant flush or major engine work.
- The difference between the 2.0 Type S overhaul capacity of 8.3 liters and the service fill of 6.7 liters suggests approximately 1.6 liters of coolant typically remains in the system during a standard service drain, which is a common characteristic of cooling systems where full drainage requires additional procedures.
- CAN and USA market variants share identical capacity specifications within each engine configuration, with the 1.5T at 5.6–5.8 liters service fill and the 2.0 Type S at 6.7 liters service fill and 8.3 liters overhaul capacity respectively.
