Check the coolant top up reservoir. Low coolant sensor is usually in the overflow/reserve container.
Wash out and clean any dirt or corrosion from the sensor prong.
Refill to correct level with fresh coolant, then recheck alarm operation.

I have the same problem with my 2002 Impala. I recently replaced the radiaor. Had to remove the Low Coolant Sensor and install onto new radiator, (its located 2-3 inches below the fill spout) now the low coolant warning light is on when I start it and drive off. clears once the engine is at operating temperature. Temperature is in good order. do I have a faulty sensor?
help me out guys, whats my next step? new Sensor?

1998 Pontiac Sunfire has a low coolant light on I changed the sensor thermostat and flushed the system including bleeding the light is still on and has no leaks and the reservoir tank is full what's...

low coolant sensors work by the fact that they need to be completely covered by water. There is current to the sender that earths out through the coolant to the engine and back to the battery earth wire.. This circuit hols a relay open so that no lights come on. When the circuit is broken ( low water --broken wire) the relay clicks in and the lights come on to let you know that there is no coolant in the system before there is damage done to the engine. So check that there is coolant. in the radiator right up to the cap ( not some in the radiator) and check that the wire is not broken at the sensor.. You may not have bled all the air out of the system (air lock) and this is affecting the sensor because there is not always water around it.

2002 ford windstar sel overheating

first check coolant level in radiator coolant level sound low.if coolant overflow jug empty.coolant sysyem low, when add coolant to coolant overflow jug coolant level should stay at full cold mark.if coolant level okay,engine overheat while sitting or moving in slow traffic either coolant fan relay or fuse could be bad.or engine coolant temperature sensor could be bad. coolant sensor turn on cooling fan at certain wire check to make sure cooling fan motor not bad or short in wires.if all is good have pcm check it controls fan relay to through the coolant temperature sensor signal when coolant get hot.

I have a 1998 Silhouette. I turn it on and leave it in parking for a long time and it does not overheats. But when a drive it for about 20 minutes it starts overheating. The low coolant light comes on not...

The low coolant light may be due to the sensor, these sensors go bad often, they are located on the front side of radiator. as far as overheating the first then i would do is a block test, this is done with a fluid to test if exhaust is entering the cooling system and stopping the flow which make it overheat, if it passes this test then i would replace the thermostant and go from there, hope this helps.

I have a 2000 silhouette. the coolant level low light keeps coming on even though coolant has been added. after about 10 minutes of idling the temp rises to just below h.but temp is fine while driving....

Bleed the air out of the coolant system,and add more coolant,to radiator,and reservoir,and make sure the cooling fans are coming on,if the low coolant light stays on,remove the low coolant light sensor,and clean it off,it is located on passengers side in the radiator,it has a wire clip you have to remove,and dont loose it,after cleaning it,put the clip back on the sensor,and push the sensor back in the hole.

Low coolant light,low oil and check engine light

Most likely it is the sensor, it is located on the radiator near the battery, it will stay off if you unplug it, Check the fuses and relays though just to make sure, oil pressure sensor possibly but again check fuses

Low coolant light won't go off, coolant level is just fine, how do I reset the light?

The light should reset itself after a few on/off cycles of the ignition, if not you may have a bad low coolant sensor.

Coolant level warning on dash board

Check your coolant level in the radiator when the engine is COLD. If it is low, add more. Also check and add as needed in the reservoir to the specified level. If these are full, then you have a bad water level sensor that will need replacement. This is a plug in the top of the radiator with a wire coming out of it. It acts much like a door switch that turns on the light when you open the door, only where the door switch is a momentary contact operated by a spring, the sensor in the radiator reads continuity based on the water level in the radiator tank. When there is no fluid, there is no continuity and the light comes on.

Hope this helps,

Monte carlo 01 runs hot, says low coolant but its full

Thermostat is probably stuck closed... Run the car with the cap of the bottle or radiator and see if it starts to circulate when it gets hot... Be careful though because it can over heat and have no coolant flowing.. And also watch for spewing fluid if it get hot at the place you took the cap off.... The low coolant could also mean the radiator is not full but the bottle is... Check for a restriction from the bottle to the radiator.. If you see a sensor on the bottle it could be bad... But That won't cause it to over heat. It'll just say low coolant because the switch is stuck.
Also does the fan come on while it's getting hot?
If not that could be the reason for the overheating.. And the coolant level sensor could be bad telling you it's low
Cap off look for circulation of antifreeze.
At the same time before it over heats make sure fan is coming on. No fan on? Fan fuse or relay could be bad... Also maybe a wire.
No circulation? Thermostate stuck or restriction in coolant hose...Line... Radiator..... And worse case scenario the water pump might be bad.
The low level I wouldn't worry about. Find out why it's over heating first.
