fla 9 Posted July 1, 2010 Just yesterday the run-on fan did not come on after switching the car off, although water was around 90-92 ish and a fairly long run. However, after driving it 10 minutes later for a short trip, it did but only for about 10 seconds. I have twin spals in mine. How could i test this, or more to the point, what exactly needs to be tested? The fan control module and/or the rad sensor? The rad is pretty new (bought from here) as is the sensor in it too.
