gar52hpny Posted October 6, 2010 Share Posted October 6, 2010 I just started the 2002 outback 2.5 with a cold engine and cold coolant, almost immediately I heard a click and the cooling fans started for about 10 seconds then turned off. That happened several times before I turned the engine off. I had heard the click previously but the short cycle seems to be new. Does anyone have any ideas what that means? Thank you...

OB99W Posted October 6, 2010 Share Posted October 6, 2010 One possibility is a defective engine coolant temperature sensor. If you have access to an OBD-II scan tool, you could check the live (real-time) data with the engine cold and see what temp is indicated. If it's not near to the ambient temp, the temp sensor might be bad. However, check first for corrosion at the connector before considering replacement.
