Nissan Pathfinder, R53 (USA / CAN)

Additional Notes

• The Nissan Pathfinder R53 3.5 V6 cooling system holds between 11.6 and 11.9 liters across all listed configurations, whether 2WD or 4WD. A capacity range rather than a fixed figure typically reflects minor variation introduced during a full drain and refill, accounting for residual fluid in passages and the heater core.
• The 11.6–11.9 liter capacity figure applies uniformly to both the 212 kW and 220 kW variants of the 3.5 V6, indicating no meaningful difference in cooling system volume between those two power outputs.
• Under normal use conditions, the Canadian-market 3.5 V6 (212 kW) in both 2WD and 4WD configurations carries a coolant change interval of 120,000 km or 60 months, whichever comes first.
• The US-market 3.5 V6 configurations, covering both the 212 kW and 220 kW outputs and both 2WD and 4WD drivetrains, share a normal-use coolant change interval of 75,000 miles or 60 months.
• The time-based component of the normal-use interval is identical at 60 months across all listed markets and configurations, even though the distance thresholds differ between the Canadian and US specifications.
• An initial service interval is listed separately from the normal interval for all configurations. For Canadian-market 212 kW variants, the initial service interval extends to 168,000 km or 84 months, which is 40 percent longer in distance and 40 percent longer in time than the subsequent normal-use interval.
• For US-market configurations, the initial service interval is set at 105,000 miles or 84 months. As with the Canadian figures, the 84-month time limit on the initial service interval is 40 percent longer than the 60-month limit applied to normal subsequent changes.
• The extended initial service interval across all configurations reflects a common practice where the factory-fill coolant is formulated to last longer than the fluid used in subsequent service fills, allowing a longer first change period before reverting to the standard normal-use schedule.
