Have the cooling system flushed, put in a new thermostat, be sure the radiator's not clogged. If it's cheap, maybe a new temp sender too. The car's possibly overheating, a very bad thing with the WHITE motor.

usually when everything seems right and that light comes on, either the fluid level sensor in the expansion tank (clear tank with green cap on passenger's side under the hood) is either broken or disconnected. You can lift the expansion tank up and check the wiring from below. It is not a float, but an internal sensor...when it gets wet, the connection is made and completes the circuit. It it is dry (lack of radiator fluid) then it opens a circuit and turns the light on in the dash. Hope this helps. I would try this before all of the replacements mentioned above. What's the temp sensor on your dash? The radiator light is not the same as the high temp. light if I remember correctly.

yeah...it is on mine...reminds me of the wee alarm we used with our kid when he was trying to keep a dry bed for the night. At least no float in mine.
