The coolant light is supposed to indicate when the coolant level is low. If you're certain that the vehicle coolant level is up, check the electrical connections and finally the sensor.
fill the coolant reserve and the light should go out
Coolant system warning light. It should go off when you add coolant.
go to auto zone they will do it for you
low coolent/anti-freeze, check the tank and make sure it is full, if not, fill it to the full line. if the light doesn't go away, i would take it some place and see if the thermostat is working correctly.
You have an air bubble. The coolant level sensor is high in the block and you need to bleed the suystem of air in order to turn the light off. Not doing so will create hot spots in the engine block and eventual failure.
when u have low coolant
You may have a faulty coolant level sensor
I am not a car guy, but my low coolant light just came on in my Saturn Vue. I checked the owners manual and it said I should add anti-freeze/coolant. If you go to a car parts store (NAPA, Auto Zone, Pep Boys), they can tell you what type of coolant to add. If the problem repeats, you probabaly have a leak in your cooling system. Good Luck!
Either the coolant reservoir is low on coolant or the coolant level sensor is NG.
Make sure the coolant level is ok, add fluid if needed, that should make the light to go out if light still on you will probably have a bad coolant level switch and will meed to replace it
The coolant level switch on a 95 Achieva has a sticking problem. If you tap the coolant tank near the sensor the light will go out
The universal coolant is a good way to go if you are not sure which it takes. The 98 Saturn has a big colored dot on the reservoir, green or orange Here's my opinion. They make a universal coolant now, perhaps Prestone or some other brand. It claims it can be mixed with ANY type of coolant... if you're not sure what it takes, go with that. Take your time flushing your coolant if it looks like mud. You may have to flush it multiple times to get all the junk out. I bought my Saturn used. When I checked all the fluids my coolant was a browish color. I ask my mechanic he told me that who had it before put both green and orange coolant in it. He flushed it and put in orange coolant.
