I like it for diagnostic purposes. Lets say I just replaced my Water Pump. And.. I forgot to tighten something to specs or whatever. The leak only appears as soon as I start driving the car. I then see the temp gauge climbing like it should, then DING "Low Coolant" So, I pull over, check the coolant, whatdaya know? The coolant is low. Let the car cool down for a minute, drive home, and I don't have to get a tow, or deal with any of that ****. With me, checking the coolant level everytime I am under the hood, there will never be a drop of coolant missing. But you cannot plan for the unexpected.

my car did the samething, the warning will come on and off when ever it wanted, i was living with it for a while but it got annoying, i even unpluged it but i warning stay on. i finally brike down and got a replacement. it only cost $30 for the senser.this is alot more enjoyable to drive the car know when i don't have to worry about the warning coming on.

if you just replaced your pump you should be under the hood checking the coolant for the fist few days.
