At what temperature does the EA888 engine's cooling fan activate?
1 Answers
Generally, the engine's radiator cooling fan starts operating at around 90 degrees Celsius. When the temperature reaches approximately 105 degrees, the fan begins running at high speed. For domestic vehicles, the fan typically activates between 93 to 95 degrees. The radiator fan automatically turns on only after the engine has been running for a certain period and the coolant temperature rises. Additional information about automotive electric fans includes: 1. Working principle: The electric fan is controlled by a thermostat - when coolant temperature reaches the upper limit, the thermostat powers on the fan which operates until temperature drops to the lower limit when the thermostat cuts power. 2. Operational requirements: The electric fan motor draws high current during operation, requiring higher-grade wiring.
