Subject: What should Antifreeze PH Be



Macon, IL		I bought some test strips and tested Ph of antifreeze in my 4630. What should the Ph be? What is high/low-or I guess I should ask at what point should it be changed?

(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.

I don't understand the chart (probably because I don't want to understand the chart)    ;)

 

The "experts" say to change anti-freeze every year, or evry two years at the longest.  Your cooling system should contain liquid that has a ph of 9 or higher.   Anything lower is eating your engine, radiator, hoses, gaskets, etc. from the inside out.  Again, the "experts" say that you can significantly extend the life of your car, truck, etc. by changing coolant (anti-freeze) every year.

The "experts" who say change antifreeze yearly probably have a profit potential in that statement. I don't trust them one bit.
The biggest question in antifreeze is how often does the machine run, and remix the various components of the antifreeze back into the liquid state. The small solids, there primarily to plug minor leaks will settle out of stationary antifreeze, and block minor passages.

PH is strictly dependant on which type of antifreeze you are using. The major difference between green and orange is the PH coming from the factory. Each has been designed to function in a different cooling system, and contains different buffers.

Somerville, Indiana		Tim, let you in on a secret...Antifreeze doesn't wear out...50% concentration will always keep your engines from freezing if you don't let them get under advertised temp.

Coolant conditioners deplete...test strips help us keep coolant in shape to keep the inside of the engine looking like new...test at least once a year, add conditioner as needed, add 50% antifreeze-distilled water for make up and never change coolant...We have machines that haven't been changed for over 20 years, water jackets still look like new.

honest.
