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.
