Nissan Maxima, A36 (USA / CAN)

Additional Notes

• The Nissan Maxima A36 3.5 carries a total cooling system capacity of 9.2 liters across all listed configurations, spanning both the Canadian and US markets and all model years from 2015-2023. A total capacity figure represents the full volume of the cooling system including the engine block, cylinder head passages, radiator, and reservoir, as opposed to a drain-and-refill figure which would reflect only what can be recovered during a standard service.
• Canadian-market specifications for 2015-2019 include a coolant level check interval of every 8,000 km or 6 months under normal use conditions. No equivalent periodic check interval appears in the 2019-2021 or 2021-2023 Canadian entries, nor in any US-market entries across the full 2015-2023 range.
• Under normal use conditions, the Canadian-market 3.5 calls for a coolant change at 120,000 km or 60 months. The time-based threshold of 60 months, equivalent to five years, reflects the degradation rate of coolant additives over time independent of mileage accumulation.
• The first-change-only condition for the Canadian market extends the initial coolant change interval to 168,000 km or 84 months. This longer interval acknowledges that factory-fill coolant is often a long-life formulation with a higher additive concentration than standard service-fill fluid, allowing the first drain to be deferred relative to subsequent changes.
• US-market specifications follow the same 60-month and 84-month time thresholds as the Canadian market, but express the distance intervals in miles rather than kilometers. The normal change interval is 75,000 miles at 60 months, and the first-change-only interval is 105,000 miles at 84 months. Converting 120,000 km yields approximately 74,565 miles, confirming the two markets share effectively equivalent distance thresholds despite the unit difference.
• The first-change-only interval of 105,000 miles or 84 months applies uniformly across all three US-market year groupings: 2015-2019, 2019-2021, and 2021-2023. No variation in either the distance or time threshold appears across any of those ranges, indicating a consistent factory-fill coolant specification throughout the A36 generation in the US market.
• The Canadian-market specifications are divided into three overlapping year groupings: 2015-2019, 2019-2021, and 2021-2023. The 9.2-liter capacity and the 120,000 km / 60-month normal change interval remain unchanged across all three groupings, reflecting no revision to the cooling system service requirements within the Canadian A36 production span covered by these specifications.
