Review on Prestone AF 1420 Antifreeze Coolant Tester by Jason Marquez
Best Antifreeze Tester
A great product that has been on the market for years but is essential for checking the quality of the antifreeze in your radiator. Easy to read, simply insert into a COLD radiator, squeeze the bulb and fill the chamber. The dial accurately shows the performance of the coolant. If you want to change your own antifreeze or check the quality of the antifreeze in your radiator, you'll need one of these. Lasts for years. I keep mine in a ziplock bag and attach it to a gallon of antifreeze in the garage. Always ready, always in action.
