SOURCE: low coolant light keep coming on. radiator full

The problem is the low level sensor.It is just below the radiator fill neck.About 3 or 4 inches down on the passengers side.It is held in by a wire clip.The best way to replace it is to let the cooling system cool down so there is no pressure build up.There is an o-ring for a seal.What I do is lube the o-ring seal before installing the sensor so it goes in easier and the o-ring will not slide off.You can partially drain the coolant just below the sensor level or just remove the sensor and install the new one.You will loose a very slight amount of coolant if your quick enough.You should be able to get one at any part store and it should not cost to much.You can call ahead to the part stores and tell them your make and model number along with the engine size.I hope this helps and good luck.

SOURCE: Low Coolant Light Staying on

This car has sensors on it. If the coolant tank is full and the system is working properly, then one of the sensors is bad.

Have the cooling system presure tested to make sure you have no leaks. If test is good, then look to the sensors.

GM has different systems for each car depending on configuration, so it is hard to point to the one that may be bad.

The CHECK COOLANT indicator illuminates when the coolant level is low in the coolant recovery reservoir. The low coolant level switch is probably in or on the coolant reservoir !

Low coolant light continues to come on. The coolant is full. Reasons why?


This is a common problem and it caused by a defective low coolant light sensor. The sensor is either located in the bottom of the coolant surge/recovery tank or in the side tank of the radiator.

My low coolant light keeps coming, i replace the Thermostat on yesterday but got in car this morning and light came right back on put water in and drove to work when i got to work cut car off look under...


Low coolant doesnt have anything to do with the thermostat. If the coolant bottle was over filled, it will push out, it needs some air space. only fill it to the full line. If the low coolant light is on, but its not really low, the sensor may be bad. Be sure to use the correct coolant DEXCOOL.

The low coolant light is on


If the low coolant light is coming on, there could be a leak in the cooling system and the system may be very low. Sometimes if the cooling system is full and there are no leaks, the low coolant sensor might have a malfunction and turns on the low coolant light.

Light came on instrument panel. looks like a water pump light.


bet it's the low coolant light. There's a senser on the side of the raditor that tells if the coolant is low and it'll come on if there's straight water in the cooling system too it'll come on if the coolant is low it'll come on if it fails and all of these are as common as the other. Sometimes you can disconnect and reconnect the senser and it'll reset ifthe raditor is full of coolant but it can go bad too just as often, Sometimes you can just unplug it and it'll not work but you;ll not know when your low if you do. New sensers are dealer idem.

Low Coolant light stays on


Check you coolant resevoir. The low coolant switch is located in the resevoir so if it is low on coolant there, the light will come on. If it is full, it could be that the switch is stuck due to gunk build up in the resevoir. Hope this helps you out
