I have a low coolant light on - no check engine light is on however. I have refilled the reservoir which did not help.

When that did not work, I removed the cap when the engine was cold. Then I ran it until the engine warmed and the thermostat opened. I thought an air bubble could have formed blocking coolant.

The engine temp guage is normal and the engine is not running hot/cold.

Any ideas?

A few weeks ago I changed some other sensors including; cam sensor, knock sensor, oil pressure switch.



Is it possibel that my engine temp/coolant sensor is also bad; where is this located? On the side of the block on the drivers side in front?

the sensor is located in the passsanger side of the radiator, its a rectangle about 2.5 in long 1.5 inches wide, try to clean the coper wire inside the sensor or just go get one from the local dealer; it was like 40 bucks i think.
hope that helps

Unplug it. It'll come on again even with a new sensor. I went through this with my `99 and the only way to get rid of the light for good is to unplug the sensor. `00+ doesn't even have the "low coolant" sensor anymore because of this problem.

Yeah, it's on the passenger side of the radiator. You can remove the battery to get a better veiw/better access to it.

Just clean it and get rid of the dexcool...thats what messing it up...dexcool gunks up the level sensor. They work fine when you do this.

I thought Dexcool is the pink stuff that is the only coolant that is supposed to be used in our cars.

How do you clean the old sensor; water?

Just unplug it.

It will return even if you replace it with a new sensor. I speak from experience.

The '00+ F-bodies don't even have this sensor in their radiators. GM must have been aware that those sensors had issues with proper functioning.

clean it with water...mine went at 30k, cleaned it now I have 64k and its still fine because I switched over to regular antifreeze with a bottle of royal purple.

i thought you could not use regualar antifreeze because it would rust out the inside of the engine!!!

I have this same problem. I cleaned mine, but a day later the light came back on. Guess I will just unplug it now.
