I turn the fans on when the water temp gets to about 170 (low temp T-stat is open). The car never gets above 190 now.  |
On my Audi s4, there was an after-run circuit that would circulate coolant and run the fans for up to 10 minutes after the car was turned off. Some people would change the temperature sensor so it ran more often, however I jumped the sensor with a switch so if I knew I wanted the car to run the fans for the full 10min, I would just flip the switch before turning it off.
I wonder if we can change the sensor that turns on the engine bay cooling fan, or if there is a similar timer that if the sensor is jumped, wouldn't just run forever.
