Unplug the low coolant level sensor. If the light and alarm stop going off the sensor is bad. Most of the time the sensor gets dirty and can't "see" the coolant. HTH. -Jim

Looks like the sensor screws into the radiator, on the same side as the radiator cap, about halfway down. You'll see an electrical connector plugged onto it. HTH. -Jim
