8. Install two bolts (A) securing the evaporativeemission (EVAP) canister purge valve bracket.
9. Connect the breather hose (B), and install the dipstick (C).
10. Connect the evaporative emission (EVAP) canister purge valve connector.
11. Install the four ignition coils (see page 4-21).
12. Install the engine cover. NOTE:
 Use fender covers to avoid damaging the painted surfaces.
 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).
5. Remove the intake manifold:  K20Z2 engine (see page 9-3)
 K20Z3 engine (see page 9-7)
6. Remove the exhaust manifold (see page 9-11).
7. Disconnect the evaporative emission (EVAP) canister hose (A) and the brake booster vacuum
hose (B).

19. Connect the positive crankcase ventilation (PCV)hose (A) (K20Z2 engine) and install the ground
cable (B).
20. Connect the fuel feed hose (A) (see page 11-331), then install the quick-connect fitting cover (B). 21. Connect the evaporative emission (EVAP) canister
hose (A) and the brake booster vacuum hose (B).
22. Install the exhaust manifold (see page 9-11).
23. Install the intake manifold:  K20Z2 engine (see page 9-4)

24. Install the drive belt (see page 4-31).
25. Install the air cleaner assembly (see page 11-345).
26. After installation, check that all tubes, hoses and connectors are installed correctly.
27. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so that the fuel
pump runs for about 2 seconds and pressurizes the
fuel line. Repeat this operation three times, then
check for fuel leakage at any point in the fuel line.
