Cylinder Head

Installation (cont'd)

14. Apply liquid gasket to the head cover gasket at the

four corners of the recesses.

NOTE:

• Use liquid gasket. Part No. 08718 - 0001 or 08718

- 0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Do not install the parts if five minutes or more

have elapsed since applying liquid gasket. Instead,

reapply liquid gasket after removing old residue.

• After assembly, wait at least 30 minutes before

filling the engine with oil.

15.
Apply liquid gasket to

the shaded areas.

When installing the cylinder head cover, hold the

head cover gasket in the groove by placing your fin-

gers on the camshaft contacting surfaces (top of the

semicircles).

Once the cylinder head cover is on the cylinder

head, slide the cover slightly back and forth to seat

the head cover gasket.

NOTE:

• Before installing the cylinder head cover, clean

the cylinder head contacting surfaces with a

shop towel.

• Do not touch the parts where liquid gasket was

applied.

• Replace the washer when damaged or deterio-

rated.

• Reconnect the grounds cables to the cylinder

head cover.
16. Tighten the nuts in two or three steps. In the final step,

torque all nuts, in sequence, to 12 N-m (1.2 kgf-m, 8.7

Ibf-ft).

NOTE:

• Be sure to wipe any liquid gasket off the surface

of the No. 7 camshaft holder where the distribu-

tor is to be attached.

• After assembly, wait at least 30 minutes before

filling the engine with oil.

17. After installation, check that all tubes, hoses and

connectors are installed correctly.

18. Enter the anti-theft code for the radio, then enter the

customer's radio station presets.
