Thread: Low coolant level alarm

but the Datatron is plugged into the top of the radiator - header tank and thermostat housing a much higher, so they could be dry for a while until the alarm on the radiator goes off?

Is this correct?

I am unsure of this too.

How much coolant do you lose before the header tank is empty and the low level is registered at the radiator? A litre or two in a total of eleven maybe?.

My humble view is that this device is for traumatic events where there is a sudden and serious loss of coolant and not a substitute for checking your coolant level on a regular basis. When the alarm goes off you stop immediately while there is still some coolant in the system not just because the level in the header tank is 1mm below the optimum.

Have a look at this set up, might be of some interest to you.

Your african link looks the easiest. When my water pump gasket sprug a leak, the only way I could tell was by constantly checking the header tank, I guess if that level goes down there is a problem.

Good Idea.
Now who can get their hands on a bulk order of those RR caps.
