Additional Notes

  • The INFINITI QX56 cooling system capacity is listed at 14.9 liters for the 2010-2013 model years, applying equally to both the rear-wheel-drive and AWD configurations.
  • A 14.9-liter cooling system capacity is relatively large, consistent with the demands of a full-size body-on-frame SUV platform housing a high-displacement V8 engine.
  • The AWD variant shares an identical 14.9-liter cooling system capacity with the standard rear-wheel-drive version, indicating the drivetrain difference does not affect coolant volume requirements.
  • Both configurations carry a "normal" use condition designation, meaning the listed capacity applies under standard operating conditions rather than severe-duty or first-fill scenarios.
