any thoughts!.
the use of the above would be desireable to illiminate the chemical reactions within the coolant system with the different metals used so has anyone used either long term?
Many schools of thought on this very subject on most Vehicle forums.....some say okay for distilled/deionised where others say not and use drinking water from the tap or bottle.....
You take your pick really..... I stand in the deionised camp personally but that is not to say that tap water is not right to use.
Indeed the conductivity of deionised water is lower due to the process it goes through.
There are another 2 thoughts, a) If you use a 50% pre-mix coolant...... what is "water" is the coolant mixed with? b) on anything electrical that "measures" a fluid by conductance the quality of components are key to the device working correctly in all circumstances. Having worked with level devices, not just for water based chemicals but for the mining and food industries too, we had to use the correct materials for the job.
I guess the choice is in the hands of the "end user" after doing their research
