When do the radiator fans kick on in 850 Volvos? And do they continue to run (for a short while) even after the car has been turned off-like A1 VW's. I am just trying to confirm that the new radiator fan that was installed(last week at the Volvo dealership in Cerritos) in my father's 850 is indeed operating properly. I drove my Mom to the office this morning on the way to the mechanic (to have the oil changed, a new sway bar end link installed, and the tires rotated), and after driving the 5 miles, the fan wasn't running. It did appear to be running (however slowly) after I brought the car to the house so my father could take it to work. Thanks in advance :)
