Toyota RAV4, XA40 (USA / CAN)

Additional Notes

• The Toyota RAV4 XA40 2.5 non-hybrid variants, covering both 2WD (ASA42) and 4WD (ASA44) configurations across 2013-2018, share an identical cooling system capacity range of 6.6-6.8 liters. The range rather than a fixed value reflects normal variation between a drain-and-fill service and a complete system overhaul that includes flushing residual fluid from all passages.
• The 2.5 Hybrid 4WD (ASA44) carries a main cooling system capacity of 7.5 liters, which is notably higher than the 6.6-6.8 liter figure for non-hybrid variants. The additional volume accommodates the expanded thermal management demands of the hybrid powertrain components.
• In addition to the main cooling circuit, the 2.5 Hybrid 4WD (ASA44) has a separate inverter cooling system with a capacity of 1.5 liters. The inverter circuit is a distinct loop dedicated to managing heat generated by the power electronics that convert DC battery power to AC for the electric motor.
• Canadian-market specifications for the 2.5 2WD and 4WD non-hybrid models set the normal-use coolant change interval at 80,000 km or 60 months. The time component of 60 months means a change is due at five years regardless of whether the distance threshold has been reached.
• Under the first-change-only condition for Canadian-market non-hybrid models, the change interval extends to 160,000 km or 120 months. This doubled interval reflects the extended-life properties of the factory-fill coolant, which is formulated to last longer than subsequent refills before its corrosion inhibitors degrade.
• US-market non-hybrid models specify a normal-use coolant change at 50,000 miles or 60 months. The time threshold of 60 months aligns with the Canadian schedule, while the mileage figure of 50,000 miles converts to roughly 80,000 km, making the distance intervals effectively equivalent across both markets.
• For US-market non-hybrid models under the first-change-only condition, the change interval is 100,000 miles or 120 months. As with the Canadian equivalent, the 120-month time limit applies regardless of accumulated mileage.
• The coolant check interval for Canadian-market models is set at 8,000 km or 6 months across all configurations, including both the main and inverter cooling circuits on the hybrid. The 6-month time interval means the system is inspected at least twice per year independent of driving distance.
• US-market models specify a coolant check interval of 15,000 miles or 18 months, which is a longer interval than the Canadian 8,000 km or 6-month schedule. The 18-month time threshold means the system may go up to a year and a half between inspections under low-mileage use.
• The hybrid inverter cooling circuit on the 2016-2018 RAV4 2.5 Hybrid 4WD (ASA44) follows the same change intervals as the main cooling system within each market. In Canada, normal use calls for a change at 80,000 km or 60 months, with the first-change-only interval at 160,000 km or 120 months. In the USA, the corresponding figures are 50,000 miles or 60 months for normal use, and 100,000 miles or 120 months for the first change.
