Additional Notes

  • The Acura MDX YD1 3.5 V6 cooling system lists two distinct capacity figures for every configuration: a dry fill and a service fill. The dry fill represents the total system volume when completely empty, while the service fill reflects the smaller amount needed during a routine coolant exchange when residual fluid remains in the system.
  • For the 2001-2002 model years in both the USA and CAN markets, the dry fill capacity is 8.7 liters and the service fill is 7.6 liters, a difference of 1.1 liters between a full drain and a standard service top-up.
  • The 2003-2006 model years carry a slightly larger dry fill capacity of 9.0 liters, while the service fill drops to 7.1 liters. The gap between dry and service fill therefore widens to 1.9 liters compared to the earlier generation.
  • USA and CAN market specifications are identical across all model years covered, with no difference in capacity figures or change intervals between the two markets.
  • Under normal use conditions, the change interval for all configurations is 96,000 km or 60 months, whichever comes first.
  • A separate first change only interval of 192,000 km or 120 months is listed alongside the normal interval for every configuration. First change only designates the extended interval applicable solely to the initial factory-fill coolant, after which the normal interval governs subsequent changes.
  • The first change only interval is exactly double the normal interval in both distance and time across all listed configurations, applying equally to the 2001-2002 and 2003-2006 model year groups.
