Accent, Tagaz, Radiator fan, Automatic transmission
On a Tagaz accent with an automatic transmission, the radiator fan is turned on by a signal from the engine ECU. The engine ECU receives a signal about the coolant temperature from the coolant temperature sensor located in the cylinder head. When the coolant temperature reaches 92-94°C, the engine ECU turns on the radiator fan at low speed, and when the coolant temperature reaches 96-98°C, at high speed.
If the radiator fan does not turn on according to a signal from the engine ECU, you need to check:
* The radiator fan itself
* Radiator fan power supply circuits
* Coolant temperature sensor
* Engine ECU
