Just wanted to know what the low coolant warning sound sounded like. Is it actually a buzzing sound or a tone sound? Got in my FD a few days ago and heard a tone and my coolant light was on for a few seconds then went away. Since then it hasn't come back on.

 

tone, same as when arming the alarm or red line...

 

Add coolant. Just like it says. Or you have a bubble in the coolant system, you'ld need to bleed the system to get rid of it. Basicaly whenever the buble hits the sensor, the buzzer goes off. Just the same, I did some radiator work, and took the car out for a drive. I made it 5 miles before the buzzer and add coolant light came on. Turned out the lower radiator hose came off. The add coolant light came on WAY before the engine temps even started to climb. This very well could have saved my engine because I don't always keep a close eye on the water temp gauge.

 

That was some nice radiator work you did
