Optimized fluid handling: Enables quick coolant changes and efficient air purging through vacuum pressurization, delivering consistent results during the vacuum filling process for vehicle cooling systems. Versatile use for SUVs and sedans: Fits both SUVs and sedans, providing a practical solution for inspecting and maintaining cooling systems across different vehicle categories. Accurate leak detection: Mechanical pressure gauge offers realtime monitoring of system leaks, enabling precise identification of issues without guesswork. Durable construction: Made with strength alloy and other quality materials to withstand repeated use and provide longlasting performance. Practical use scenarios Scenario 1: In a performing a routine coolant change on a midsize SUV, connect the kit and use vacuum to purge air, then fill to a consistent level for reliable cooling system operation. Scenario 2: After completing a cooling system on a sedan, apply pressure and monitor the mechanical gauge to verify there are no leaks and that the system holds pressure. Scenario 3: Fleet maintenance across a mixed fleet of SUVs and sedans: use the tester kit to inspect cooling systems for leaks and ensure proper filling during service intervals.
