The low coolant alarm is actually telling you something, but only Haydn speaks the coolant alarm language. Over the 10 years we had our bongos I loved ours, never any false alarms, 2 real alarms after a water pump failure, and a pipe leak. I fitted about 10 to other people's without issues. You can even use them to bleed the coolant system using the seesaw method to listen for the level in the expansion tank, I fitted the high level add-on that Haydn made in limited numbers, this helped you bleed the system with your eyes closed.
I noted that occasionally I did repairs to the Lecky systems on bongos that accompanied coolant alarm squeals or activations,these were usually related to low voltages seen at the alarm wherever it was taken from,usually an ignition switch live as advised.
Alternator problems, battery issues or glow plug or circuit/relay etc are the usual.
After the starter battery has started the engine particularly in harder to start colder months when the glow plugs can be on off for quite a while, the starter battery is recovering from the starting hammering it's just had, the alternator may also be slow to up it game, the lights and wipers go on, the Aircon demist goes on is it hard to imagine the voltage seen at the low coolant sensor may dip slightly, this dip is not as evident when the glow plugs are fresh and the alternator is quick to up its game etc. I always listened to the coolant sensor as it was telling you something was not quite right.
I'm not related to Haydn, or have any connection to jo, I have used their alarms for years without any gripps, they do have their limitations but they are an aid and nothing more, with a bit of common sense they are the best I've found to do the job.

Ps. Haydn, I will pm you my address for the Xmas card. Lol.

You are, of course entitled to your criticism but equally we are entitled to respond.

He changed the terminal ring - and probably did a better job of it than me. He told me that hadn’t managed to get any false alarms from it.
I drove it two miles home and there wasn’t a single squeal.
Drove ten miles to work this morning. All was well. 8 miles in it squeaked for ten seconds. Off for two minutes. Squeal. Off.
On way home squealed three times for 30 seconds at random times.
Will see how it is tomorrow. I don’t have much time at the moment to work this out so may go back to garage to switch it off if it gets worse and come back to it later.
Thanks for all help so far.
