I've used several types of Antifreeze Testers over the years and this one is my favorite. This Tester is easier to read, Holds a good quantity of fluid so you can visually check for contaminates provides a more accurate reading (my opinion). When Testing make sure that fluid completely fills the Tester when held upright, gently tap the Tester Body to shake loose any air bubbles, Hold the Siphon Tube up so your Fluid doesn't drip out give it a couple of seconds for the arm to settle. Reading on 1 side shows how Cold your anti-freeze will protect down to on the other shows the Boiling Point your engine is protected to. After Testing you can simply squirt the fluid back into your Cooling System. Make sure you then Flush the Tester with clear water to remove any traces of anti-freeze.Taken care of this Tester will last many years for you to use.
