6. Start the engine and run it until it stalls.
7. After the engine stalls, crank it for five more seconds.
8. Turn the ignition switch to OFF.
9. Remove all spark plugs. Spark Plug > REMOVAL">
10. Install the compression gauge to the spark plug hole.
NOTE:
When using a screw-in type compression gauge, the screw should be less than 25 mm (0.98 in) long.
11. Connect the battery ground terminal. NOTE">
12. Turn the ignition switch to ON.
13. Depress the accelerator pedal to full throttle.
14. Crank the engine by starter motor and read the value when the needle of the compression gauge becomes stable.
NOTE:
• Perform at least two measurements per cylinder, and make sure that the values are correct.
• If the compression pressure is out of standard, check or adjust the pistons, valves and cylinders.
Compression pressure (at 200 — 300 r/min):
Standard
1,050 — 1,400 kPa (11 — 14 kg/cm2, 152 — 203 psi)
Difference between cylinders
100 kPa (1 kg/cm2, 14 psi) or less
15. After inspection, install the related parts in the reverse order of removal.
