The reed switch may be stuck. My 98 Grand Am coolant tank ran dry last week when my lower intake manifold gasket started to leak. Fixed the leak and refilled the tank only to see the coolant light still on. Tapped the switch/sensor on the bottom OS the tank with a rubber mallet so the magnetic float could loosen up and float back up. Sure enough, turned on the ignition and light was out.
You can reset the 2001 Buick Century low coolant warning light by removing the fuse. Keep the fuse out for 10 seconds, then replace it to its original spot.
fill the coolant reserve and the light should go out
I have a 2002 alero how do you reset, the coolant light is always on. Thanks, Alero owner
To reset the low coolant light in a 2000 Silhouette, first ensure that the coolant level is topped off in the reservoir. Next, turn on the ignition without starting the engine, allowing the dashboard lights to illuminate. Once the low coolant light is on, press the gas pedal three times within five seconds to reset the warning light. Finally, start the engine to confirm the light has been reset.
There is no way to reset the light. If the light is on, then either the coolant is low, the float is stuck or the sensor is bad.
there is no reset you have replace the low coolant sensor and flush cooling system and use dexcool coolant.
Reset the battery
you may need to replace the sensor for the coolant, there should be a wire connected to it.
Add more fluids
you get coolant and fill it up
If it is the low coolant light, it may mean your coolant is low. If it is not low, it may be the low coolant light sensor malfunctioning.
It's a warning sign that you are low on coolant.
