Lang Tools Cylinder Leakage Testers (CLT-2C)

The Lang Tools Cylinder Leakage Testers (CLT-2C) is an indispensable diagnostic tool designed to precisely identify and locate internal engine problems. Unlike a standard compression tester that only indicates overall pressure, the CLT-2C measures the percentage of air leakage from a pressurized cylinder, allowing you to pinpoint the exact source of an issue. This makes it a crucial instrument for diagnosing worn piston rings, faulty valves, cracked cylinder walls, or blown head gaskets, saving time and effort in engine repair. Utilizing shop air pressure, the CLT-2C provides clear, quantitative data through its dual-gauge system, enabling both professional technicians and dedicated DIYers to maintain engine health and performance effectively. Its robust construction, made in the USA, ensures reliability and accuracy, making it a valuable addition to any automotive toolkit.

KEY FEATURES AND BENEFITS:

• Accurate Leakage Measurement: Dual gauges provide precise readings, showing both input air pressure and the exact percentage of air leaking from the cylinder, allowing for specific problem identification.
• Targeted Diagnostics: Helps pinpoint the exact source of engine issues such as worn piston rings (indicated by air escaping the oil filler/dipstick), leaky valves (air from intake or exhaust), or blown head gaskets (air escaping to the cooling system).
• Complements Compression Testing: Offers a more detailed analysis than a standard compression tester, providing actionable insights into the condition of internal engine components.
• Precision Air Regulation: Equipped with a precision regulator to ensure consistent and accurate air pressure delivery to the cylinder for reliable test results.
• Comprehensive Adapter Set: Includes essential M14 standard-reach and long-reach solid adapters to accommodate common spark plug sizes, enhancing versatility.

SPECIFICATIONS:

• Gauges:
• Leakage Gauge: 2.5-inch diameter, 0-100% leakage scale in 5% increments, multicolored band (white face, black numbers).
• Input Pressure Gauge: 2.5-inch diameter, 0-100 PSI range in 2 PSI increments, dual scale with PSI and bar.
• Hose Assembly: 26-inch rubber hose assembly.
• Included Adapters: M14 Standard Reach Adapter, M14 Long Reach Solid Adapter.

HOW TO USE:

1. Prepare the Engine: Ensure the engine is at normal operating temperature and then turn it off. Remove all spark plugs from the engine.
2. Locate Top Dead Center: Rotate the crankshaft until the piston of the cylinder you wish to test is at Top Dead Center (TDC) on its compression stroke. This is crucial to ensure both intake and exhaust valves are fully closed.
3. Connect the Tester: Thread the appropriate M14 adapter from the CLT-2C into the spark plug hole of the cylinder you are testing. Connect the hose assembly to the adapter.
4. Connect to Air Supply: Attach the CLT-2C to your shop air supply.
5. Pressurize the Cylinder: Open the valve on the tester to allow compressed air into the cylinder. Adjust the regulator until the input pressure gauge reads the recommended testing pressure (typically 100 PSI or as specified by the engine manufacturer).
6. Read Leakage: Observe the leakage gauge to determine the percentage of air escaping the cylinder.
7. Identify Leakage Source: Listen carefully for the sound of escaping air.
• Air from the oil filler cap or dipstick tube: Indicates worn piston rings.
• Air from the intake manifold or throttle body: Suggests a leaking intake valve.
• Air from the exhaust pipe: Points to a leaking exhaust valve.
• Bubbles in the radiator or coolant reservoir: Indicate a blown head gasket or cracked cylinder wall.
8. Repeat for Other Cylinders: Repeat the process for each cylinder to get a complete picture of your engine's internal condition.
