you may have a bad sensor or lose sensor check to see if the wireing is rubbing on anything i belive if you have too much water in relation to antifreeze then the light wll come on, have your coolant tested at a service station to make sure you are using the correct ratio.
you can't reset it, fill your coolant up full, both rad and overflow. the light will go out. if it is still on when everything is full, then your coolant sensor is broken or unplugged. if you light goes off then comes on again and your coolant is low, then you have a leak. if you have a 3400 engine in your lumina common leaks are intake gaskets, waterpumps, and head gaskets.
usually when you add coolant light goes off Coolant sensor bad?
That is were the coolant goes when it expands. Sounds like coolant isn't circulating or it is being forced out of the system.
not really. check that oil isn't in your coolant or coolant in your oil. the 3.1L engines seem to have a reputation for bad intake manifold gaskets.
when the engine is running and coolant will become hot to its operating temperature,the cooling system is under pressure,coolant will overflow and goes to coolant reservoir.when the engine goes cold coolant will go back to the rediator.

Green coolant
It has one. Sometimes they get stuck on even after you add coolant. Tap on the reservoir until the light goes off. Or you could always unplug the connector at the bottle and the light will go off. That's at your own risk of course because you won't know when you're low on coolant.
Coolant goes in the radiator or you can also fill the radiator resevoir.
The coolant goes into the reservoir only that says coolant. You don't put it in the radiator.
The coolant resevoir on a mercedes is the same as it is on any vehicle it just might be a different shape. Your coolant resevoir is where you store excess coolant and where exess coolant from your radiator goes.
Belt slipping Did coolant get on belt during replacement?
