Also check the sensors. There are 3 sensors starting from the end of the block. The first one at the end of the block is for engine/coolant temperature, the second one is the for the sending unit and third one-2 pronged blue sensor is for the aux fan (105 -115c) and may this could be faulty. Use a multimeter to check resistance on the 3rd sensor. If you don't have one, Sears has one on sale for $9.99. Check your service manual for correct resistance values. It is either your thermostat, sensor or fuse and all these parts are very cheap to replace. Good Luck
