Thread: 02 GP Coolant Light

I have a 2002 GP with about 180k miles on it. Recently, the coolant light has been turning on despite there being plenty of coolant in the radiator and the engine running at normal temps (it has a new thermostat/temp gauge). I proceeded to change the coolant level sensor with a junkyard part, but the symptoms didn't change, so i'm assuming there's something else going on here. Has anyone hear of/seen this before? What's the next thing I should look for?

Why does this happen? Is the harness going bad?

Like Scotty said dex sludge blocks the sensor hole and you can have a full radiator with the sensor sitting here n a pocket of air. Or sludge on the sensor itself.
