Thread: 2002 GP 3.8 V6 coolant level sensor

I would imagine that the coolant completes the circuit somehow, since when the light comes on the coolant level is usually below it. Just my guess tho. I just keep mine unplugged so it doesn't send any false lights if it gets gunked up. Been that way for 10 years and never an issue. And yes, I check my coolant level every oil change.
