Does anyone heard the fan under the hood will always turn on for few second?? Is that normal??
I believe one fan is turned on by the coolant temperature sensor mounted on the radiator.Originally posted by TEG:
I think the IS300 is different.
Is seems to have 2 electric fans that are not clutched to the engine.
There must be some temp sensors and/or ECU that decide when to turn those fans on/off...
