Are you checking the coolant cold? If the light comes on while cold, add a little to bring it just over the minimum line. If it's coming on when you are warmed up, then it should always be on when you are cold. At any rate, if the addition of some coolant puts it out, problem solved. If not, then you may need a new level sensor. It is a float type proximity switch and is not adjustable as far as I know. Relatively inexpensive to replace...and a very necessary warning system component to have working right 100% of the time..
