Electric Powertrain Cooling: Overview
Electric Powertrain Cooling - Component Location
NOTE:
Coolant temperature will vary with ambient temperature and load. Temperatures shown are for ambient temperature of 50deg. C (122deg. F). Red arrows indicate a temperature over 70deg. C (158deg. F), Orange arrows indicate a temperature of approximately 70deg. C (158deg. F), Blue arrows indicate a temperature below 70deg. C (158deg. F).
