Default Coolant light

So my gf has a 2005 Saturn ion-2 and her coolan light keeps coming on within minutes after startup. Iv looked at it, a mechanic has looked at it, can't seem to figure it out. Is this a normal problem with Saturn ions? Need some advice here on what the problem might be or where to start.

Thanks!

Low on coolant and needs topping off? Often if coolant hasn't been replaced with a complete flush then old coolant eventually precipitates and builds up on the float that dips lower into the coolant. While coolant may look filled to the level mark the float drops a little lower and turns on the low coolant indicator.

Either drain and flush the cooling system or top off about an inch higher than the full mark.

Yeah maybe I should double check her reciept n make sure she got a flush. She told.me she did but idk I don't trust most places anymore. Ill double check all that but last I knew that was all fine.

Usually this is because the .sensor is gummed up and you need to replace the tank. Few have been able to clean it, and none to my knowledge have been able to "fool" it like fdryer suggests.

Sounds like your low coolant light is from your radiator reservoir.. I cleaned mine out and worked like a charm..

on ions, cleaning seems less common to work. not that one shouldn't try, it's just not guaranteed to work.
