On my 2001 Pontiac Grand Prix, the coolant level sensor in the radiator near the battery would get gummed up. You can lower the coolant level in the radiator, remove the battery, and remove the sensor. Clean it and replace the coolant. I was having to do this yearly. One common problem on these Pontiacs is a leaking plastic lower intake manifold gasket set. A small amount of oil can contaminate the coolant and lead to this build up on the sensor and thus the coolant light illuminated. I changed the l.i.m. gaskets on my car with the improved all aluminum replacement gasket set. In my opinion, this is a very good engine but why GM went with these plastic gaskets is beyond me!!

On the side of the radiator, by the filler neck? This is the only low coolant sensor I know of. *Ditto here; There is only one for temp and another for coolant level. Each sets off a different warning light on the dash.
