Why is my coolant level low?
If your car’s coolant level is dropping, it is almost always due to leaks in the cooling system – the hoses, radiator or radiator cap, for example. Symptoms of this can be a rising temperature gauge, a sweet odour (the smell of antifreeze), problems with your car’s heater or increased fuel consumption.
Why does my GMC 2500 have a low coolant light?
A good diagnosis goes a long way. Would’ve saved you from having to buy 2 coolant tanks. I have a 2017 GMC 2500 HD with the 6.6 Duramax. The truck now has about 35,000km on it and the low coolant message is appearing at almost every start up. The tank is not low but I topped it off right to the cap and the message still pops up.

Can a PCM turn off a low coolant light?
Yes. If the light goes out then the switch is bad. If not then you could possibly have an open wire and the pcm isn’t seeing that the switch is closed thus keeping the light on. A multi-meter can tell you if a wire is open. Yes.
What to do if your coolant light is not working?
You’ll need to find the wires at the PCM that come from the switch. Then with a multi-meter set on ohms you put one lead on the wire at the PCM and the other lead on the wire at the switch. If it reads OL then the wire is open. If you get some numbers then its not open. If its open then just run a new wire from the pcm to the switch.
