    So I fitted that coolant level sensor today, the one from CarTekMotorsport. They were really good at shipping it to me, followed up every day to check if I'd received it. Works very well and is very sensitive from what I've seen today. And the alarm buzzer is LOUD! I think even a small drop in coolant level will set the alarm and warning light off, even though it is fitted in the top hose just where it enters the rad.

    Any news on the CarTekMotorsport cooland flow system installed? Working fine? No false alarms due to sensitivity?

    My father in law has an unit. He sells them for R350.
    Very simple system that beeps when the water runs out of the radiator.

    He actually gave me one after I lost a head on my Ford ranger.
    He gave DVR one when we picked up my bakkie from him to test as well.

    Don't know if it worked for him or if he has issue with it but for me it works, only problem I have is the wire gets corroded so what I do is use a connector block remove the sleeve and when the buzzer starts buzzing when there is water in I remove the old connector and replace it.

    Bought this little 12volt water level float from micro robotics in Centurion and installed it in the radiator bottle. Easy and seals properly. Went to comunica today and bought a 12 volt buzzer, red led and inline fuse. Will complete the installation tomorrow. When water level is just above minimum the alarm will be activated.

    Toppie4x4.. I don't know whether you have a "closed" system. My Landcruiser 1Hz has an "open" system and will supplement coollant due to vacuum in the radiator.
    IMO...
    In an "open" system the coollant in the reservoir will not be supplemented when a radiator hose burst as there will not be a vacuum in the radiator. The reservoir will stay full while the radiator/enjin runs dry!

    Can you tell us more about it, what it is and how it is fitted, post some pics?
    Does he sell them on a website?

    Default Low Coolant Level Sensor/Alarm

    Two years on and the CarTek Motorsport coolant level alarm is still working perfectly. It measures the water level in the top radiator hose and sounds an alarm as soon as this water level drops. It also beeps when you turn the vehicle on to let you know it is working.

    The link to where I bought it in 2017 is in post #32, but sadly they appear to have discontinued them.
