it doesnt take much to turn that light on...mine came on, and gradually got worse. turned out the water pump was bad....only 45K on it. never even leaked on the ground, burned off on the engine, i could only see it by looking closely or feeling the bottom of the pump

Yup, my water pump went bad at about 72k, and the light stopped coming on after i changed it, but the past few weeks it comes on everyday, but my coolant is always good to go. oh well, damn 4.3L
