Suitable coolant / Corrosion inhibitor.

[Rob Beale]

pH means Hydrogen Index. It is a German language term, like ABS!

The pH scale measures the acidity or alkalinity of a substance on a scale from 1 to 14
pH 1-2 is extremely strong Acid, pH7 is neutral and pH13-14 is extremely strong Alkali
Examples of the 3 are stomach acid, distilled water and Caustic soda.

Note that rain water is slightly acidic due to dissolved CO2 from the atmosphere about pH5.5

Coke is about pH3.5 which works like other acidic rust converters.

Baking soda is weak alkaline, and is good for neutralising acid spills on car batteries and terminals.


My reading of the quotes from Lynn is that we want stronger alkaline pH levels in our engines
