whining low coolant alarm.....

[B*Witched Blingo]

Did he say it was Conductive properties of the Coolant and the sensor having a reduced conductivity as the coolant strength was reduced thus an alarm raised or something along those lines.

Hi folks.....we get this every winter......the test beep/flash will be longer the colder it gets.......also because it takes more out of the battery in colder weather to start the Bongo and as the alarm is voltage sensitive then you can get a chirpy/tweet for a couple of mins till the coolant warms up.
Combine all this with a slightly weak coolant and the alarm will object....as with useing lights/wipers etc. Nothing to worry about.
If the alarm sounds and stays on a while on start up then check the level in the tank...if thats o.k. all should be well after a min or so.
The replys above more or less cover it......
If your battery is very discharged then the alarm will "mummer"

I can 3rd that after a little over two years with mine, I reckon its an even cleverer gadget than we give it credit for.

Its possible to identify a variety of chirps & whines on start up, after a while.

For about 18 months I lived with a weep that guzzled about a pint of coolant a week, usually topping up on a Sunday. The whine got noticeably longer come Thursday/Friday then by Sunday it would stay on at the first click of the key, thus hitting the low mark.

In the early months it was just topped up with water which resulted in the self test blip getting longer as the mixture became more diluted. Once coolant was changed (& lesson learnt ) it became a crisp chirp again.

Haydn may be able to explain how it seems to know.

Its like the mystery of the thermos flask Chris,it keeps hot drinks hot,and cold drinks cold.....but HOW DOES IT KNOW ????

And all was well with the bongo again..............................
