The Prestone Professional Antifreeze/Coolant Tester is a precision diagnostic tool designed to measure the concentration of ethylene glycol in your vehicle’s cooling system. For those living in Missouri, where winter temperatures can plummet and summer heat can be intense, knowing your coolant’s freezing and boiling points is essential for engine health. This professional-grade tester uses a high-visibility pointer and a clear scale to provide an immediate readout, allowing you to determine if your mixture is sufficient to prevent the engine block from cracking in the winter or boiling over in the summer. Its durable, impact-resistant housing is built to withstand the rigors of a busy garage, making it a reliable staple for both professional mechanics and DIY enthusiasts.
Key Features of Prestone Professional Antifreeze/Coolant Tester
Additional Information
To get the most accurate reading, ensure you draw enough fluid into the tester so that the pointer can float freely without touching the sides of the housing. If the coolant appears rusty or cloudy while inside the tester, it is a sign that the corrosion inhibitors have broken down and the system should be flushed and refilled, regardless of the temperature reading. Always perform this test when the engine is completely cool; opening a radiator cap on a hot engine can lead to serious burns from escaping steam and pressurized coolant.
