Radiator Cooling Fan Stays On S70

jda2000 pretty much called it. The temp sensors go bad in these cars all of the time and you have to pull the thermostat housing out of the way to get to it so you might as well just toss in a new thermostat while you have the old one out. I replace them all of the time for posting codes as well as leaking coolant right through the center of them. If they post a code for that sensor it will put the fan into default mode and it runs at half speed all of the time as well as running on for a few minutes after the car is shut off.
