Our Pro Series Versatile Coolant Tester is designed to work with diesel engines, RVs, and marine applications, ensuring that you have an accurate and reliable resource at your disposal. Key Features: Accurate at All Temperatures: Whether your engine is hot or cold, our disc-type tester provides precise readings of your coolant’s freezing point, safeguarding against both under and overprotection. Easy to Read: Simply count the number of floating discs within the coolant to determine your antifreeze's effectiveness. The clear design allows you to match it easily against the chart printed on the body of the tester. Prevents Overprotection: Includes a special 6th disc that indicates potential overprotection and inefficiencies due to a poor water-coolant mix, ensuring your coolant remains effective. Powerful Yet Simple Design: The transparent body of our tester enables quick visual checks for impurities such as rust, providing you with immediate insight into your engine's health. Universal Compatibility: Perfect for testing diesel antifreeze, RV antifreeze, marine antifreeze, and more, our coolant tester adapts to almost any vehicle's coolant with unmatched ease. Ensure Efficient Engine Protection: Our radiator coolant tester accurately verifies hot or cold ethylene glycol-based coolants, including those featuring Dex-Cool. With six discs magnified by the convex design of the thermal-resistant plastic barrel, the first five discs provide a freeze indicator reading, while the 6th disc alerts you of potential overprotection. The ideal measurement is five floating discs — a freeze protection level of -34F or -37C. Even if your next coolant flush isn’t on the horizon, regular testing is key to maintaining a robust coolant environment for your engine. This indispensable tool allows you to assess your antifreeze for impurities and debris easily, potentially signaling the need to schedule an earlier coolant flush. If you take your engine's protection seriously, our simple yet powerful coolant kit deserves a place in your toolbox!
