3. Before removing the spark plugs,
clean the area around the spark
plugs using compressed air.
It is important to prevent foreign
materials from falling into the cylinders
once the spark plugs are removed.
4. Disconnect the coil wire from the
coil, and remove all spark plugs.
Note the position of the wires so that the
correct wire may be replaced on each
plug at the end of the job. On engines
with two spark plugs per cylinder,
remove only one plug per cylinder.
5. Remove the oil dipstick, radiator
cap, and disconnect one end of
the PCV hose. If the engine has a
carburetor, remove the air cleaner and
open the throttle all the way. If the
engine is fuel injected, remove the air
cleaner or open the throttle body.
6. Position the cylinder to be tested
at TDC on the compression stroke
so all valves are closed.
7. Install correct size Spark Plug
Adapter onto end of Adapter Hose,
then thread Adapter with attached
Hose into spark plug hole of cylinder
to be tested. Connect the male
end of the Adapter Hose to the
female coupler on the Tester.
8. Turn the Pressure Regulator Knob
fully counterclockwise. Connect
a compressed air source (not
included) to the air inlet plug on
the Cylinder Leak-Down Tester.
9. Turn the Regulator Knob clockwise
until the regulated Pressure Gauge
reaches desired input test pressure.
Make sure the test pressure used
is 10 PSI less than the maximum
pressure produced by the air source,
but not greater than 100 PSI.
NOTICE:
DO NOT operate this Tester
with the input air pressure set higher than
100 PSI, which can damage the tool.
10. The pressure in the cylinder being
tested is indicated on the Leakage
Gauge. The amount of leakage
in the cylinder is determined by
comparing the difference in pressure
between the two gauge readings.
11. Turn the Pressure Regulator Knob
fully counterclockwise before
disconnecting the Adapter Hose. Test
the remaining cylinders to determine
which cylinders are bad, if any.
12. Use the diagnostic techniques
in the next section to determine
the cause of the problem.
