Comments about Custom Accessories Antifreeze Tester:

I tried to use this and tested it on distilled water. 5 balls were floating indicating good antifreeze protection. Water should read NO BALLS.
I tried to use soap to remove any contamination, but this did not work.
DO NOT TRUST THIS PRODUCT TO READ CORRECTLY.

    Comments about Custom Accessories Antifreeze Tester:

    Right out of the box, my engine coolant made two balls float. Upon quickly rinsing a couple of times and testing in water, all five balls floated...What?? I set it aside, considered returning it, and also worried there could possibly be oil in my coolant. A couple of hours later, I decided to try again, but this time after thoroughly flushing the device. It then read, consistenly, 0 balls floating for water, 5 balls for my coolant, and 0 balls for water again. There must be residue in the device from manufacturing that interferes with readings straight out of the box. WASH THOROUGHLY WITH CLEAN WATER BEFORE USE. A little soap only helps as long as you rinse it out well. The device is working consistently now, and doing what it should be doing.

      Comments about Custom Accessories Antifreeze Tester:

      I have used these little bulb style antifreeze testers for years and have not had much problem. Lost mine today and bought 3 of these just so I would have a few extra on hand when I needed to find them. Out of the three, only TWO of them held liquid (the third had a leaky bulb so all the liquid would drain out before I could get a reading unless I covered the bottom with my finger). ALL THREE of them floated anywhere from 1 to 5 balls (not even consistently) when tested with PLAIN WATER straight out of the package. WORTHLESS junk....very poor quality.

        Comments about Custom Accessories Antifreeze Tester:

        I DECIDED TO PURCHASE THIS PRODUCT AFTER READING THE FIRST REVIEW. I HAD ONE OF THESE FOR ABOUT 20 YEARS IN THE 80'S AND 90'S. WORKED GREAT BUT THE BULB DETERIORATED. I BOUGHT A TESTER THAT HAD THE POINTER AND NEVER REALLY TRUSTED IT. THIS TOOL IS BASED ON A PROVEN PRINCIPLE...THE MORE DENSE THE WATER...THE MORE BALLS WILL FLOAT. THE MORE ANTIFREEZE IN THE SOLUTION THE MORE BALLS WILL FLOAT....QUITE ACCURATE. SO, I WONDERED WHY ALL BALLS WOULD FLOAT WITH PLAIN WATER AND TODAY FOUND WHY. I TESTED MY AUTOS AND IT WORKED PERFECTLY.... I THEN TESTED MY SON'S CAR AND FROM THE BEGINNING HAD DIFFICULTY WITH THE CORRECT NUMBER OF BALLS FLOATING. HIS CAR HAS A BAD HEAD GASKET WITH OIL IN THE WATER. WHEN THE BALLS BECOME COATED WITH OIL (SINCE OIL IS LIGHTER THAN WATER) ALL THE BALLS FLOAT EVEN WITH PLAIN TAP WATER. I CLEANED WITH A DROP OF DISH DETERGENT AND THE TOOL WORKED CORRECTLY. THIS TOOL WORKS ACCURATELY FOR THE MONEY. IF YOU HAVE PROBLEMS...YOU MIGHT NEED A 15 DOLLAR TOOL. SO, IF YOU'RE HAVING PROBLEMS WITH THIS TOOL, YOU MAY HAVE PROBLEMS WITH YOUR MOTOR.

        Just a toy

        By 

        from San Antonio TX.

        Comments about Custom Accessories Antifreeze Tester:

        I tested this product with tap water and the five balls floated; this means that my truck will be protected all the way to -40 with just water which is not true.

            This tester determines the specific gravity of the coolant which determines if the coolant is good or bad.
