Acura CSX (USA / CAN)

Additional Notes

• The Acura CSX 2.0 (CAN) cooling system holds 6.45–6.6 liters on a dry fill, which represents the total system volume when completely drained and refilled from empty, such as after a major repair or component replacement.
• The CSX 2.0 (CAN) service fill capacity of 4.2–4.3 liters is notably lower than the dry fill figure, reflecting the volume used during a routine coolant flush where residual fluid remains in the engine block and heater core passages.
• The reserve tank on the CSX 2.0 (CAN) holds 0.4 liters, a separate figure from both the dry and service fill capacities, accounting for the overflow reservoir volume.
• The CSX 2.0 Type-S (CAN), covering model years 2007-2010, carries a slightly wider dry fill range of 6.45–6.75 liters compared to the standard 2.0 trim, suggesting minor variation in cooling circuit volume between the two configurations.
• The Type-S service fill range of 4.2–4.5 liters also spans a broader window than the standard 2.0 trim's 4.2–4.3 liters, indicating greater variability in residual coolant retention across Type-S cooling system servicing.
• Both configurations share an identical reserve tank capacity of 0.4 liters, meaning the overflow reservoir design is consistent across the standard and Type-S variants despite differences in main circuit volume.
• All coolant capacity figures across both configurations are listed under normal use conditions, meaning the specified volumes apply to standard operating environments rather than severe-duty or extreme-climate scenarios.
