Thank you! Done and done. Drove 60 miles no issues other than I over filled the overflow.

 

the fans will stay on untill you move air thru the car again. If Sitting, the fans will simply stay on and do their job. They won't go off untill you start driving again. At least in hot weather.

 

fans come on if the temp gets above a certain level, if the a/c is on, if the system is in diognostic mode, if the system is forsed into open loop by a failing sensor. they do not come on just because the car is not moving.
