Now, I kind of understand what is going on my radiator fans.
Coolant temperature sensor sends the temperature value to the ECM while coolant temperature sender
send the signal to the indicator on the driver'* pannel. So the indicator shows the right temperature of
the coolant because the coolant temperatuer sender is working fine.
However, due to the falure of the coolant temperature sensor that is supposed to give the value to ECM, the two radiator fans are not spinning.
So if my conclusion above is correct, I should replace the SENSOR not sender, am I right?
Thanks in advance for your comments.
