Our 2011 Subaru Outback 3.6R, which we bought brand new back in Feb ’11 and only has 4k miles, seems to be having issues with the cooling fan. The cooling fan will come on when the engine is cold and it will stay on the entire time the engine is running. I’ve read that the cooling fan will run the whole time when either the A/C is on or the vent control is set to defrost, regardless of whether the engine is cold or hot. In my case, the cooling fan comes on when the engine is cold, even with the HVAC off and it will remain running at full speed when the engine is running, again with the HVAC off.
Every time I go to start the car after it has been sitting for an entire day and the engine is cold, when I turn the key to the “On” position, before the engine is even started, the cooling fan comes on. How is this possible when the engine isn’t even running and the engine is cold. Again, the HVAC is off. Once the car is started, the cooling fan will remain on until the car is shut off. The fan is running as such a high speed you can hear it over the noise of the idling engine. Once I turn the car off the fan shuts off.
Since we’ve owned the car there were two other issues First, the transmission pan gasket wasn’t properly installed and it was leaking transmission fluid. That issue was fixed and is good now. The second issue was that oil was leaking from the timing chain cover. It turns out that the timing chain cover gasket was also improperly installed. This too was fixed, and doesn’t seem to be a problem anymore.
Could the cooling fan be running irregularly due to broken sensors? Could it be a bad thermostat? Do you think something could have been broken or incorrectly reinstalled when the technician had to remove the timing chain cover to fix the timing chain cover gasket?
Any feedback is appreciated.
