Im having an issue with my coolant temp gauge after my header install. When moving the alternator to do my motor mounts i accidentally broke the plastic plug on the sending unit. I replaced the sending unit, and the gauge seemed to be stuck at 210. Im sure i have the right sending unit, i unplugged it and the gauge dropped to zero. Then i plugged it back in and now every time i start the car it goes to about 150 for a second then drops to zero, and the fans kick on immediately. Any ideas?
