Low Coolant Light... But There's Plenty of Coolant

2002 Chevy Silverado 2500 HD 6.0 False Low Coolant indicator
This was periodically happening to my truck as well: 'Low Coolant' on the message center, but there was plenty of antifreeze mix in it.
Instead of buying a new reservoir just for the sensor/ float in the bottom, I simply took the reservoir off and cleaned it out with a long pipe cleaner and some super green. Next, I rinsed it out and checked to see if the float worked (since I could now see through the sides).
Finally, I rinsed the reservoir out again, refilled it with coolant, reinstalled in my truck and it has been working great ever since!
No more false 'Low Coolant' message!
