Coolant question?

Neither of those articles tells how much drain cleaner or lemon juice to add to 6 quarts of coolant to change the PH by a point.

For guys who want to test pH more, I'd suggest just getting a tester. The strips are hard to read and cumbersome. Testers are pretty cheap these days -- about the cost of a couple test strip kits. Lot more accurate too.

This is the one I have. It works great. I think it's .01 accuracy. I use it also for checking boiler system water (for heating). It comes with pH solutions for calibrating and testing. I keep the solution in airtight containers for double-checking accuracy. I haven't noticed much drifting of accuracy. Pretty good tool for $10.

We are just adjusting ph, not antifreeze protection. A standard hygrometer will tell you your freeze protection, but you need ph testing to tell if the coolant is detrimental to the materials in your cooling system. It's like apples and oranges, two different things entirely.

OK, got the new test strips and came out between 7.5 and 8, with 50% glycol.

Too bad you can't use pool water testers because they rely on clear liquid for color change. I have several and have used them for about 40 years. And you are right about the electronic ones. They suck!

Amazon says i bought it in August. Ive used it about once a month since then. Still works. I havent calinrated it since i got it. Havent seen any wild swings in ph readings either.

Is distilled water fine for making the solution, or do I have to track down deionized water?
