Get the coolant flushed. The properties of the coolant get diminished and create a situation where you'll have to spend more time here. :)
The coolant level sensor may be part of the cap on the reservior or at the bootmo of the reservior. You see and electrical harness going to it either way. It may not change when you tap on it or it may. I don't recall any other problems that I encountered for triggering that light, unless the reservior was really low.
