Additional Notes
- The INFINITI QX60 L51 (USA) cooling system capacity is listed as 11.6–11.9 liters across all covered configurations, a range that reflects normal variation during a service fill depending on how completely air is purged from the system during the refill process.
- The FWD and AWD variants of the 3.5 share identical cooling system capacities of 11.6–11.9 liters, indicating the addition of the rear drivetrain hardware does not alter the engine cooling circuit volume.
- Under normal use conditions, the coolant change interval is set at 75,000 miles or 60 months across all listed configurations, meaning whichever threshold arrives first would govern the service timing.
- A first change only interval of 105,000 miles or 84 months is specified separately from the normal interval, reflecting the extended service life of factory-fill coolant before the standard recurring schedule takes effect.
- The 30,000-mile and 24-month gap between the first change only interval and the subsequent normal interval illustrates that the initial factory coolant fill is formulated or conditioned to last longer than subsequent service fills.
- The 2021 and 2022 model year entries carry identical capacity and interval figures for both FWD and AWD configurations, with no numerical differentiation between the two model years in the specifications.
