   Crank the engine for no more than 5 ~ 10 seconds.

8. Inspect all the spark plugs.

   Tightening torque: 

   14.7 ~ 24.5 N.m (1.5 ~ 2.5 kgf.m, 10.8 ~ 18.1 lb-ft)

9. Using a spark plug socket, install the spark plugs.
10. Install the ignition coils.

    Tightening torque: 

    9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

    NOTE: When inserting ignition coil into the cylinder head cover for spark plug to be inserting ignition coil, the sealing cap of ignition coil must be mated totally with inner side of cylinder head.
