If you are saying that it comes on now and then, and goes off, your may just need to add Anti-freeze/boil to the overflow tank. Does it come on when you're coming to a stop or going up or down a hill, if yes, add coolant to the overflow tank to bring it up to the correct level, not the radiator.

A small loss over a long period of time is acceptable, but constant refilling, indicates a leak either internally, with the coolant exiting through the exhaust, or one that you should see under your car occasionally. Sometimes you'll find your coolant leak in the floorboards if the heater core or hose leaks.

If your sensor comes on after driving a while & goes off as a result of adding coolant, then you'll probably need to pressure test the cooling system to identify where the coolant is going. Bad hose, seal, headgasket, head, etc.

Good luck !

Check the collant level in the coolant bottle. If low add coolant. If it is O.K, then you must have a bad coolant level sensor. It is located inside the bottle and is not serviceable, so you need another Coolant Bootle, and it cost about $60. Before replacing, I would try to remoce the coolant bottle and give it a good cleaning with hot water. You can replace it witha new one, or try the luck in a junk yard.

overfill tank

peak proformance 50/50 coolant is the best i believe. its very cheap and can be found at any general store

check and make sure there is fluid in your radiator
