This comprehensive kit provides technicians and serious DIYers with the means to accurately measure cylinder compression, a critical indicator of engine health and potential issues. Engineered for precision and ease of use, the TU15-53 helps in identifying problems such as worn piston rings, faulty valves, or head gasket leaks, allowing for timely repairs and efficient engine maintenance. Its robust construction ensures reliable performance in demanding workshop environments, making it a valuable addition to any automotive tool collection. The set comes neatly organized in a durable plastic case, ensuring all components are secure and easily accessible.KEY FEATURES AND BENEFITS: Comprehensive and user-friendly: Includes a TU-15 gauge with dual scales (0-1000 PSI and 0-70 bar) for versatile measurement. Quick air release: Integrated deflator allows for efficient pressure release and immediate re-testing. Durable and flexible hose: 16-1/2 inch wire-reinforced hydraulic hose with quick-coupler and swivel for easy, secure connection. Wide engine compatibility: Supports diesel engines from GM, Isuzu, Ford/Navistar (including 7.3 TDI), Audi, Mercedes, Peugeot, Toyota, VW, Volvo, and more. Broad adapter set: Includes TU-15-1A through TU-15-6, TU-15-14, TU-15-17 (for Cummins in Dodge SUVs & Trucks), and TU-15-22A.SPECIFICATIONS: Gauge Range: 0-1000 PSI, 0-70 bar Hose Length: 16.5 inches Included in Kit: TU-15 Gauge Wire-reinforced hydraulic hose with quick coupler and swivel Adapters: TU-15-1A, TU-15-1B, TU-15-1C, TU-15-1D, TU-15-1E, TU-15-1F (TU-15-1A thru TU-15-6), TU-15-14, TU-15-17, TU-15-22A Red plastic storage case HOW TO USE: Prepare the Engine: Ensure the engine is at normal operating temperature. Turn off the engine and allow it to cool slightly to a safe handling temperature. Disconnect the glow plug harness or fuel injectors, depending on the engine design and specific test procedure. Remove Glow Plugs/Injectors: Carefully remove all glow plugs or fuel injectors from the cylinders you intend to test. Connect the Tester: Select the appropriate adapter and thread it into the glow plug or injector port. Connect the quick coupler of the testers hose to the adapter. Perform the Test: Open the throttle fully. Disable the fuel system and ignition system if applicable. Crank the engine for at least 47 compression strokes or until the gauge reading stabilizes. Record Readings: Note the compression reading and release pressure using the deflator button before testing the next cylinder. Repeat and Compare: Test all cylinders and compare readings. Differences over 1015% may indicate issues.BENEFITS OF USING LANG TOOLS DIESEL COMPRESSION TEST SET (TU15-53): Accurately identifies engine wear such as worn piston rings or valve issues before major damage occurs. Broad compatibility reduces the need for separate tools for different engines. Streamlines the diagnostic process, allowing for faster checks. Helps extend engine life by supporting preventive maintenance. Facilitates informed repair decisions based on actual cylinder performance.FEATURES: Snap-in lens on the gauge for protection.
