Professional Ethylene Glycol Antifreeze Tester For Cars And Trucks, Disk Style Readout Of Freezing Point And Proper Water To Coolant Mixture, Easy To Read In Hot Or Cold Engine Conditions
✔️ Disk-style freezing point readout, water-to-coolant mix check
This coolant tester is a compact kit designed to measure the freezing point of ethylene glycol antifreeze and verify the proper water-to-coolant ratio. It reads accurately in hot or cold engine conditions and helps guard against coolant overprotection.
✅ Disc-style readout shows freezing point; five floating discs indicate optimal protection.
✅ Includes a 6th disc to flag overprotection and poor mix.
✅ Clear body makes rust and impurities easy to spot.
✅ Works with cars, trucks, diesel, RVs, campers, and marine antifreeze.
✅ Dex-Cool compatible and glycol-based coolants are readable with this tester.
💡 What is an antifreeze tester used for and how does it protect engines? This handy tool helps verify coolant protection and the correct water-to-ethylene glycol mix in engines. - handy for quickly checking freezing point in hot or cold conditions - shows if the mix is too rich or too lean for optimal protection - helps detect rust, debris, or impurities that signal a coolant flush - works on most vehicles including cars, trucks, RVs, campers, and marine engines
