Toyota Aygo, XB40 (EU)

Additional Notes

• The Toyota Aygo XB40 (EU) 1.0 VVT-i cooling system holds between 3.6 and 4.3 liters across all model years from 2014 to 2021. A range like this typically reflects variation between a partial drain-and-fill service and a full system flush, where the lower figure represents a partial refill and the upper figure accounts for a complete overhaul capacity.
• Under normal use conditions, the cooling system interval calls for a check every 30,000 km and a full coolant change every 90,000 km. A normal use classification generally refers to standard driving patterns without prolonged idling, extreme temperatures, or heavy towing.
• A separate first change only interval is listed alongside the normal interval for all 2014-2021 configurations. Under first change only conditions, the coolant change is extended to 150,000 km while the check interval remains at 30,000 km. A first change only designation typically means the factory-fill coolant has a longer initial service life before the standard recurring interval takes effect.
• The 60,000 km difference between the normal change interval of 90,000 km and the first change only interval of 150,000 km reflects the extended protection period associated with long-life factory-fill coolant formulations, which are engineered to resist degradation longer than standard refill fluids.
• The cooling system capacity and both service intervals remain identical across all five production period groupings of the 1.0 VVT-i engine, spanning 2014-2015, 2015-2018, 2018-2019, 2019-2020, and 2020-2021, with no variation in any specified value across the entire 2014-2021 range.
