1. Thoroughly clean the head cover gasket and the

groove.

2. Install the head cover gasket (A) in the groove of

the cylinder head cover (B).

3. Check that the mating surfaces are clean and dry.

4. Apply liquid gasket, P/N 08717-0004, 08718-0001,

08718-0003, or 08718-0009, evenly to the chain
case and the No. 5 rocker shaft holder mating areas.
Install the component within 5 minutes of applying
the liquid gasket.

NOTE:

• If you apply liquid gasket P/N 08718-0012, the

component must be installed within 4 minutes.

• If too much time has passed after applying the

liquid gasket, remove the old liquid gasket and
residue, then reapply new liquid gasket.

5. Set the spark plug seals (A) on the spark plug tubes.

Place the cylinder head cover (B) on the cylinder
head, then slide the cover slightly back and forth to
seat the head cover gasket.

6. Inspect the cover washers (C). Replace any washer

that is damaged or deteriorated.

7. Tighten the bolts in three steps. In the final step

tighten all bolts, in sequence, to 12 N·m (1.2 kgf·m,
8.7 lbf·ft).

NOTE:

• Wait at least 30 minutes before filling the engine

with oil.

• Do not run the engine for at least 3 hours after

installing the head cover.

• To avoid damaging the wire and terminals, unplug

the wiring connectors carefully while holding the
connector portion.

• Connect the Honda Diagnostic System (HDS) to the

data link connector (DLC) (see step 2 on page 11-3),
and monitor the engine coolant temperature (ECT)
sensor 1. To avoid damaging the cylinder head, wait
until the engine coolant temperature drops below
38 °C (100 °F) before loosening the cylinder head
bolts.

• Mark all wiring and hoses to avoid misconnection.

Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.

1. Relieve the fuel pressure (see page 11-322).

2. Drain the engine coolant (see page 10-8).

3. Remove the air cleaner assembly (see page 11-345).

4. Remove the drive belt (see page 4-31).
