what things set off the coolent buzzer/alarm? and how often is it a false alarm?

mine is going off constantly and i found out it was the water level sensor. check the front of the thermostst housing there is a black plug,looks like a bolt head. make sure the wire is connected to it because mine melted off ( black wire ) and made the buzzer go off. just ordere a new one it was around $42 from malloy mazda.

Low coolant level. I've never heard of one falsing, but I could be wrong...

austinsFD

what about a broken or leaking pipe?

2 things will set off the buzzer:

1. the coolant level sensor; and

2. a disconnection b/w a white single wire connector located right behind the PS pump; I think it's a low oil level sensor.

Both must be in working order or the buzzer will not shut off.

Your coolant level is too low. Add more to the filler neck when the car is cold. If you shine a flashlight down the filler neck when the car is cold, you'll probably see the level below the sensor. You sensor is working as it should.
