Additional Notes
- The Nissan Sentra B18 2.0 cooling system holds 7.1 liters when paired with a CVT transaxle, compared to 6.9 liters with a manual transaxle. The 0.2-liter difference reflects the additional coolant volume routed through the CVT's thermal management circuit.
- The 7.1-liter and 6.9-liter figures apply to both the CAN and USA market configurations across the 2019-2021 model years, meaning the transmission-based capacity split is consistent regardless of market.
- Initial service intervals for the CAN market are set at 168,000 km or 84 months. The extended duration of the first interval is characteristic of long-life coolant formulations, which are designed to maintain corrosion inhibitor effectiveness well beyond conventional coolant service periods.
- Subsequent CAN market coolant changes are scheduled at 120,000 km or 60 months. The reduction from the initial interval reflects the diminished reserve capacity of the coolant's additive package after the first full service cycle.
- USA market initial service intervals are expressed as 105,000 miles or 84 months. The 84-month time limit is identical to the CAN market figure, while the mileage equivalent aligns closely with the 168,000 km distance when converted.
- Subsequent USA market intervals are set at 75,000 miles or 60 months, mirroring the same time-based structure as the CAN market while expressing the distance component in miles rather than kilometers.
- The 2021 CAN and USA entries carry the same capacity and interval values as the 2019-2021 rows. The capacity figures of 7.1 liters with CVT and 6.9 liters with manual transaxle remain unchanged from the earlier configuration.
