The low coolant sensor is bad or disconnected.
Engine coolant in an Alero is used in the radiator. A diagram and instructions for how to properly use the coolant can be found on the package instructions. An owner manual will also assist in proper use of coolant.
Radiator stores engine coolant for circulation throughout the engine The radiator is placed at the front of the engine and exposed to the atmosphere to keep coolant cool to maintain proper engine temperature
If the coolant reservoir can not maintain the proper level of coolant, it is possible the engine could over heat when the level drops.
The Pontiac Montana engine will overheat if the coolant gets low and is not refilled properly. If coolant is added, an air block WILL OCCUR preventing proper circulation unless owners manual is followed. There are 2 blleeder valves in coolant system. They must be opened & closed in proper sequence (see manual) or engine will overheat. I know-been there!

The coolant level is checked at the coolant tank in the passenger front corner of the engine compartment . The coolant level should be up to the cold mark when the engine is cold . The radiator should be full so its covering the top plate .
Yes, you can. But if you leave in cold area you will have to replace with proper coolant closer to winter. Otherwise it will damage not only your radiator but also the engine.
What does your owner's manual say to use? If low silicate is not listed then drain and refill with the proper coolant.
Do not have your car on. First step is to make sure your car has enough engine coolant, if you are low, buy some at the store and put it in its proper place for your car(If you do not know where that is then consult your owner's manual for engine or engine coolant.) If that is not the problem, then it is possible that you have a leak somewhere from the coolant container to your engine. Either check for any possible holes or loose connections or take it into an auto repair shop.
You should have a thermostat that keeps the engine coolant temperature at 180 or 195. If you are in a cool climate the 195 will work best.
Check the coolant reservoir in the engine compartment. There are marks to assist you with proper level. If it's empty you need to add coolant ASAP.
Remove the coolant reservoir, flush it out, reinstall it and refill with proper coolant.
To add coolant to and 1985 Mercedes 380se find the reservoir located in the engine bay next to the radiator. Make sure to use the proper mixture of coolant to water ratio and pour until the appropriate level. Overfilling can lead to sprouting a leak while the engine is running.
