Additional Notes

  • The INFINITI Q40 cooling system holds 8.5 liters of coolant, with an additional 0.8-liter reservoir capacity that accounts for the expansion tank separate from the main circuit fill volume.
  • Both the rear-wheel-drive Q40 and the AWD variant share identical cooling system capacities of 8.5 liters plus a 0.8-liter reservoir, indicating no difference in cooling circuit volume between the two drivetrain configurations.
  • Under normal use conditions, the coolant change interval is set at 75,000 miles or 60 months, whichever comes first, applying equally to both the standard and AWD variants.
  • A first change only interval of 105,000 miles or 84 months is specified for the Q40 and Q40 AWD, reflecting the extended service life of the factory-fill coolant before the standard recurring interval takes over.
  • The gap between the first change only interval (105,000 miles / 84 months) and the normal interval (75,000 miles / 60 months) represents a 30,000-mile or 24-month extension granted specifically to the initial factory coolant charge.
