  post locked   antifreeze types and floating balls  

I have an old floating balls antifreeze tester. Very common. You draw the fluid up into a clear pipette and count the number of balls that float in the liquid sample. I bought some 'green' coolant (says is good for all cars) last fall and I swear I diluted it 50/50. I needed some today and tested it. Only 2 balls float. That's only good to +5F. I don't believe this is right. Do all types of antifreeze work in these floating ball tools?

Thank you.

Yes, the tester works the same for all coolants but I would disagree with the one size fits all on the green coolant. That's just not true. They may make a color that blends in with the other colors but the chemical properties are very different.

Well, it appears that the balls in my old tester have a shelf life. The thing is over 30 years old.

I didn't believe what I was reading so I popped out the balls and put them in a highball glass half filled with
water. Then I added antifreeze in small steps. I got two balls to float but the other 3 never left the bottom.

I went out and purchased a new tester and now all is well. It reads as it should. Just thought I share this.

Thank you.

OK, thanks for reporting back. Closing this now as solved.
