Additional Notes
- The INFINITI QX50 3.0d J50 cooling system holds 12.9 liters, a notably larger capacity than the 3.7 V6 variant, reflecting the greater coolant volume demands of a diesel engine block and its associated cooling architecture.
- Across both the 2013-2014 and 2014-2017 3.0d configurations, the 12.9-liter cooling system capacity remains unchanged, indicating consistent engine cooling hardware across those production spans.
- The 3.0d cooling system carries a normal-use change interval of 60,000 km or 36 months, while the first change only condition extends that initial interval to 80,000 km or 48 months, reflecting a longer-life factory fill used at the point of manufacture.
- The 3.7 V6 cooling system capacity varies by transmission type in the 2013-2014 specification: automatic transmission configurations hold 9.2-9.6 liters, while the manual transmission configuration holds 9.7 liters, a difference attributable to variations in coolant routing or transmission cooler integration.
- In the 2014-2017 3.7 V6 specification, only the automatic transmission capacity of 9.2-9.6 liters is listed, with no manual transmission figure present.
- The 3.7 V6 normal-use change interval is 60,000 km or 48 months, which is a longer time-based interval than the 3.0d's 36-month normal-use schedule, despite both sharing the same distance threshold of 60,000 km.
- Under the first change only condition, the 3.7 V6 cooling system extends to 90,000 km or 60 months, compared to the 3.0d's first change only interval of 80,000 km or 48 months, making the V6 factory fill interval the longer of the two by both distance and time.
- The 3.0d cooling system check interval is set at 20,000 km or 12 months across all listed configurations, while the 3.7 V6 uses a shorter distance-based check interval of 15,000 km at the same 12-month time frequency.
