2010 - Cylinder Leakage Tester
- Measures the ability of an engine cylinder to hold compressed air using shop air pressure and supplements a compression tester
- Helps detect bad valves, worn rings, cracked cylinder walls and blown head gaskets
- Includes precision regulator with combination M14 and M18 adapter, with a 26" hose assembly
- Dual gauges allow monitoring of input air-line pressure
- MADE IN USA
- Turn regulator knob fully counter-clockwise (do not connect spark plug adapter hose yet).
- Connect regulator to shop air supply (50-150 PSI). Turn regulator knob clockwise until the right hand regulator gauge reads to the middle of the area marked “set”
- Tool is now ready to connect to the engine.
- Allow engine to run until sufficiently warm.
- Remove air cleaner, radiator cap (use caution when removing radiator cap from a hot engine) crankcase filler cap and all spark plugs.
- Place cylinder to be tested on “Top Dead Centre” (T.D.C0 on the compression stroke. (So that exhaust and intake valves are closed.)
- IMPORTANT – Ensure vehicle is in park or neutral with ignition “off” and apply handbrake. Keep hands and clothing away from engine bay, as engine rotation may occur.
- Hand tighten adapter hose into spark plug hole and connect other end into the quick coupler on the tester.
- Regulator gauge will now read percentage of leak down occurring in cylinder. Readings for each cylinder should be noted and compared after test.
- The left-hand pressure gauge indicates the air pressure going into the cylinder. It is important that all cylinders be tested at the same air pressure.
- Due to standard engine clearances and normal wear, no cylinder should be expected to maintain a perfect, no-leak reading. It is important that all cylinders have a relatively consistent reading.
