Chevrolet Bolt (USA / CAN)

Coolant capacity & service interval

Chevrolet Bolt (USA / CAN) uses coolant with a capacity range of 2 to 7 liters. Service intervals require a change every 150000 miles or 60 months. The data covers 12 configurations.

Additional Notes

  • The Chevrolet Bolt (USA / CAN) carries three separate coolant circuits, each with a distinct capacity: 7 liters for the high voltage battery cooling system, 3.8 liters for the power electronics cooling system, and 2 liters for the heater cooling system.
  • The high voltage battery cooling system holds the largest volume at 7 liters, reflecting the thermal management demands of a large traction battery pack compared to the smaller ancillary circuits.
  • The power electronics cooling system capacity of 3.8 liters sits between the battery and heater circuits, consistent with the heat rejection requirements of inverters and motor drive electronics in an electric drivetrain.
  • The heater cooling system at 2 liters represents the smallest of the three circuits, a capacity typical of a compact auxiliary loop dedicated to cabin heating rather than high-load component cooling.
  • All three coolant circuits across every listed configuration share an identical service interval of 150,000 miles or 60 months under normal use conditions, meaning no circuit calls for more frequent attention than another.
  • The 60-month time limit on the coolant change interval means a calendar-based threshold applies regardless of mileage accumulation, which is relevant for low-mileage vehicles that may reach the time limit before the distance limit.
  • Capacity figures are identical across the Bolt EV (2016-2017), Bolt EV (2017-2020), Bolt EV (2020- ), and Bolt EUV (2021- ) configurations, indicating no variation in coolant circuit sizing between those variants for any of the three systems.
  • Service intervals are also uniform across all listed Bolt configurations and model year ranges, with every circuit specifying 150,000 miles or 60 months under normal use conditions regardless of variant.
