Additional Notes
- The INFINITI QX70 3.0d V6 S51 carries the largest cooling system capacity across all engine variants at 13 liters, reflecting the additional thermal management demands of a diesel powertrain compared to the petrol V6 and V8 options.
- The 3.7 V6 petrol cooling system holds 9.7 liters, while the 5.0 V8 petrol system requires between 10.7 and 11.6 liters depending on configuration, with the range indicating variation between specific build or equipment differences within that engine family.
- On the 3.0d V6, the first-change-only interval extends the initial coolant drain to 80,000 km or 48 months, compared to the standard normal-use cycle of 60,000 km or 36 months. Subsequent changes revert to the shorter normal-use schedule.
- The 3.7 V6 and 5.0 V8 petrol engines share a first-change-only interval of 90,000 km or 60 months, which is notably longer than the diesel equivalent. After the first change, both petrol engines follow a normal-use interval of 60,000 km or 48 months.
- Coolant check intervals differ between the diesel and petrol engines. The 3.0d V6 specifies checks every 20,000 km or 12 months, while both the 3.7 V6 and 5.0 V8 specify checks every 15,000 km or 12 months.
- The 3.0d V6 specifications cover two distinct production ranges, 2013-2015 and 2015-2017, yet the capacity and interval values remain identical across both ranges, indicating no cooling system specification change between those periods.
- Similarly, the 3.7 V6 and 5.0 V8 specifications are split across 2013-2015 and 2015-2019 ranges, with all capacity and interval figures remaining unchanged between the two periods for each respective engine.
