| (from a google search) - The problem comes when the Ph of water 7.0 to 7.2 and antifreeze Ph is 10.5 right out of the container. A 50/50 mix of water and antifreeze would have a Ph factor of 8.75. This level is too acidic for today's cooling systems. The recommended Ph level should be between 9.8 and 10.5; this level greatly reduces the acid content, that together with electrochemical reaction of dissimilar materials causes electrochemical degradation.
