Quick comment about the advice above to drain the ET to reseat the cooling level sensor...
Not necessary at all...the sensor sits in a dry part of the tank. No coolant will come out from sensor hole. It only rotates 90 degrees to get tight...iirc...maybe 180 degress...but it doesn't 'turn' a full rotation.
