Acura ILX, DE2 (USA / CAN)

Additional Notes

• The Acura ILX, DE2 cooling system capacities vary across engine configurations, ranging from 5.18 liters in the 1.5 Hybrid to 6.5 liters in the later 2.4 i-VTEC variants, reflecting differences in engine displacement and thermal management requirements.
• The 1.5 Hybrid (2012-2015) carries the smallest cooling system capacity at 5.18 liters, which aligns with the hybrid powertrain's more compact internal combustion engine component relative to the non-hybrid variants.
• The 2.0 i-VTEC (2012-2015) has a cooling system capacity of 5.33 liters, placing it between the 1.5 Hybrid and the 2.4 i-VTEC of the same generation in terms of coolant volume.
• The 2.4 i-VTEC (2012-2015) holds 5.5 liters of coolant, the largest capacity among the first-generation configurations, consistent with the higher displacement engine generating more heat output.
• The 2.4 i-VTEC saw a notable capacity increase from 5.5 liters in the 2012-2015 generation to 6.5 liters in the 2015-2022 generation, indicating a revised or enlarged cooling circuit in the updated model.
• The 2015-2022 2.4 i-VTEC specifications for the USA and Canadian markets share an identical cooling system capacity of 6.5 liters, meaning no regional variation exists in coolant volume between the two markets for that configuration.
• All five configurations across the 2012-2022 model range use a flexible service interval governed by an on-board maintenance system, meaning coolant service timing is determined by the vehicle's monitoring system rather than a fixed mileage or time schedule.
