Coolant sensor goes off at random times?

[Phoenix7]

yes, It's never buzzed at me since. When the car is cold and not under pressure then you won't find the leak that's causing the buzzer to go off. Do a pressure test and see if you can find the leak.



TUrns out that the hot coolant would evaporate when under pressure and at operating temps so I never say a puddle or leak. When I tested my system I was peed on by the T-stat neck so that's how I found the crack.
