Additional Notes
- The Acura MDX YD2 3.7 V6 cooling system carries a dry fill capacity of 9.2 liters, a figure that reflects the total volume of the system when completely empty, as encountered during a full engine overhaul or major component replacement.
- The service fill capacity of 7.3 liters represents the amount of coolant needed during a routine drain and refill, where residual fluid remains in the engine block, heater core, and other passages that do not fully drain.
- The difference of 1.9 liters between the dry fill and service fill values indicates the volume of coolant that typically stays trapped in the system during a standard service procedure.
- Both the 2007-2010 and 2010-2013 3.7 V6 configurations share identical dry and service fill capacities, meaning the cooling system volume remained unchanged across the full 2007-2013 production span of the MDX YD2.
- Both configurations are listed under normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty or high-stress driving scenarios.
