radiator coolant testing/ph

have a question on checking the radiator coolant Ph., a friend we were camping with over the weekend recommend I do periodically. I replaced the radiator and coolant in the spring and added Fleet Charge as recommended by Freightliner.
I called NAPA and they sell a test strip for testing the fluids- is this the proper way to test or is there a better way?

thanks-
Steve

That's what I use. There are a few more expensive testers, but I prefer the strips.

are you getting yours at NAPA? do you the name of the strips or all they all pretty much the same?

thanks

The test strips test for ph, SCA, and 2 others, for which, I forget. I had to buy a bottle of 50 strips, which state they are good for 1 year after opening. I later found out you can buy just 1 or 2 from a truck repair shop sometimes.

I went to an auto supply and bought some test strips - and they said right on them they were not to be used for testing "red" anti freeze?

Testing for acid content is easier with a (DVOM) digital volt ohm meter. Just stick the + lead in the coolant. Don't let it touch the metal in the radiator just liquid. Then touch a good ground with the Neg. If the acid content is up you have everything you need to create a small battery. At least two different metals: brass, copper, lead, aluminum etc. and acid. That makes a battery. Your DVOM set on low DC Voltage scale will show a voltage.

Don't ask me what voltage would tell you that the amount of acid in the coolant is to high because i can't remember. Maybe somebody else has done this and would know. I'd suggest checking a freshly cleaned system and and take a reading. Then check dirty systems and determine the voltage spread. I think a voltage up in the 3-4 volt range would be high. The high acid content is more corrosive to the cooling system. That's why it is checked.
