    HEY Boys and Girls-This thing REALLY works.
    Just did a flush on my 04 Grand Marquis-
    1st I tried it plain distilled water-read as expected-ZERO protection-Zero temp. Tried it in 1st drained gallon. Read as expected. Tried in diluted AF and water-protection was lowered. Tried in car w/50-50 mixture read as expected.
    I am convinced-It really works!

            I always just guessed when I had the right mix of water and anti-freeze. I thought it was about time I got one of these to actually check it. Very simple to use.

                • Q:

                  The peak antifreeze tester has calibrations on the side for sea level. What type of adjustments should you make for 6300 feet?

                    A:

                    I'm glad to assist, Lu! This will provide a boiling point/freeze point for an antifreeze water solution at sea level using a 15 psi radiator cap. Because automotive systems are pressurized using the tester requires no additional adjustments to be made.

                  How is this supposed to work? I tried it with coolant/anti-freeze and again with plain water and the needle pointed staight up in both situations.

                    A:

                    I woked in an oil/lube shop for over two years and we had these type of coolant testers but I was like you. I could never get an accurate reading so I personally stopped using them. There are other testers that work alot better than this one.
