scotte6 Posted January 17, 2012 Share Posted January 17, 2012 I just got the engine back in my 04 Legacy and the cooling fans run as soon as I turn the key on. I ran it for about 20-30 mins and the heat gauge did not move. Are these both related to the temp sensor? Link to comment Share on other sites More sharing options...
Gloyale Posted January 17, 2012 Share Posted January 17, 2012 First, make sure the defrost is off. (fan runs anytime Defrost is on) If it still does same thing, Sounds like the temp sensor is unplugged. Check on the top of the engine, passenger side, under the rear of the manifold. Triangular shaped connector with 3 pins. Link to comment Share on other sites More sharing options...
scotte6 Posted January 17, 2012 Author Share Posted January 17, 2012 Sorry, forgot to add that point that the defroster is off. I think I was on the right sensor earlier today. It is plugged in. I unplugged and re-connected to make it it was making a good connection. There was two wires going to it and I think one was white with blue trace and the other was a yellowish color. Does that sound right? That was one thing I checked over because it made sense that something was left unplugged but I can't find it! Link to comment Share on other sites More sharing options...
nipper Posted January 17, 2012 Share Posted January 17, 2012 Did anyone plug the two green connectors together under the dash? Link to comment Share on other sites More sharing options...
scotte6 Posted January 17, 2012 Author Share Posted January 17, 2012 Nothing was done inside the car. It did not do this before pulling the motor to change the head gaskets. Link to comment Share on other sites More sharing options...
nipper Posted January 17, 2012 Share Posted January 17, 2012 So you did it yourself? Link to comment Share on other sites More sharing options...

Mugs Posted January 17, 2012 Share Posted January 17, 2012 It is easy to "flip" the triangle shape connector "upside down" and sill have it connected with a "positive" click. When this is done it flips the power wire over to the "fan on" pin and will keep the fans on all the time. Unplug it and flip it back over. This time you should see that it lines up with a grove and hear a positive/louder click and not be able to pull it off the sensor like you could when it was flipped upside down. Try that and report back. Link to comment Share on other sites More sharing options...

scotte6 Posted January 18, 2012 Author Share Posted January 18, 2012 I have attached a picture to make sure we are talking about the same sensor. If we are, it was plugged in correctly. Still no good. Link to comment Share on other sites More sharing options...
scotte6 Posted January 18, 2012 Author Share Posted January 18, 2012 sorry...another try at the pic. Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 18, 2012 Share Posted January 18, 2012 (edited) Wrong connector. That's the evap purge control solenoid. Look lower. It's that greyish one attached to the brass fitting down behind the wire harness about mid-left in that pic.
