So my car had been sitting for about an hour after taking a test drive to see if the new temp sensor would fix my high temp readings(which it seemed to for a little while and then it seemed to go back to reading hot), and I turn the key on and my cooling fan goes on because I have the fan thermostat turned all the way down to where I think it clicks on at 95 degrees, and I watch the temp gauge come up to halfway ....and I thought WHAT!!! theres no way it could still be that hot! and then for shits I turn on the headlights ( because I somehow thought that the draw on the electrical system was tied into it reading high) and the temp goes up almost to 3/4....so I double checked and I could make the temp go up and down with the lights....Anyone ever heard of something like this happening? I just replaced my temp sensor thinking that it was the problem(running hot), but noticing this, there seems to be other demons at work. Any ideas besides the obvious that it might be a short somewhere?
