Does this remedy itself or do the screws need removing & cleaning?

This happens at this time every year.
Because of the low temps the alarm will 'mutter' for a min or two until the coolant temp reaches about 10C......
If you change your coolant and replace it with RED coolant.....it will coat the inside of the system with a protective layer, in doing this it also coats the LCA sensor screw causing the alarm to play up......if you put up with this for a couple of weeks until the coolant has finished the coating process, remove the screw and wire brush it.....all will now be well.......or contact. [email protected]. For a replacement screw. (please send a SAE)

The alarm need coolant of the correct strength to work properly......plain water is not good enough. 30/50% is what the alarm likes best

Thanks for the info. I'll give the screw a clean.

In answer to the question, no I haven't bled the system yet, because I'm replacing the thermostat tomorrow. I just topped up with plain water just to give a bit of cooling while I move the van around on the drive. I'll fully drain it and refill and bleed after that.

With regard the the screw, isn't it just a stainless steel self tapper?

Just to clarify, does that mean the alarm will go off falsely in plain water (which I'd expect if its conductivity is low, as is that of air)?

A LCA will not work properly in plain water

The screw is 316 SS and the correct thread and length for the Bongo system........mess about with this at your peril .....

But to clarify, would you expect it to go off (BEEP) falsely if immersed in plain water? Or are you saying its behaviour in plain water is just unpredictable. And out of interest, what % anti-freeze must you have in the system before it can be expected to work properly?
