Replace the timing belt at 105,000 miles (168,000 km)
according to the maintenance schedule {normal condi-
tions/severe conditions). lf the vehicle is regularly driven
in either of the following conditions, replace the timing
belt at 60,000 miles (U.S.A.l 100.000 km (Canada).
- ln very high temperatures (over 110'F, 43"C).- In very low temperatures (under -20"F. -29"C).
Turn the crankshaft pu\ley so the No. 1 piston is at
top dead center (TDC).
Remove the guard bar and splash shield (see page

Gylinder Head
Removal
Engine removal is not required for this procedure.
l!@ Make sure iacks and safety stands are
placed properly, and hoist blackels ale attachgd to the
correct position on the engine.
NOTE:
o Use fender covers to avoid damaging painted sur-
faces.
o To avoid damage, unplug the wiring connectors care-
fully while holding the connector portion.
. To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F (38'C)
before loosening the retaining 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.

Installation
Installthe cylinder head in the reverse order of removal:
1. Clean the cylinder head and block surfaces.
2. Clean the oil control orifice. Install the cylinder headgasket, dowel pins and the oil control orifice on thecylinder block. Always use a new cylinder head gas-ket.

4. Tighten the cylinder head bolts in two steps. In thefirst step tighten all bolts, in sequence, to about 29
N.m {3.0 kgf.m,22 lbf.ft); in the finat step, tighten inthe same sequence to 85 N.m (8.7 kgf.m,63 lbf.ft).
Use a beam-type torque wrench. When using a pre-
set-type torque wrench, be sure to tighten slowly
and do not overtighten.
lf a bolt makes any noise while you are torquing it,loosen the bolt, and retighten it from the 1st step.

ldle Control System
System Description
The idle speed of the engjne is controlled by the ldle Air Control (lAC) Valve'
The valve changes the amount of air bypassing into the intake manifold in response to electric current controlled by the
ECM/PCM. When the lAc valve is activated, the valve opens to maintain the proper idle speed.

IAC VALVE
INTAKE MANIFOLD
After the engine starts, the IAC valve opens for a certain time. The amount of air is increased to raise the idle speed
about 150 - 300 rpm.
when the cootant temperature ts row, the lAc valve is opened to obtain the proper fast idle speed The amount o{
bvoassed air is thus controlled in relation to the engine coolant temperature
When the idle speed is out o{ specification and the scan tool does not indicate Diagnostic Trouble Code (DTC) P0505
or P1508, check the following items:
. Adjust the idle speed (see page 11-169, 170)
. Air conditioning signal (seepagell-1551
. ALT FR signal (see page 1l-159)
. Starter switch signal (see page 11-16'1)
. A,/T gear position signal (see section 14)
. PSP switch signal (seepagell-162)
. Brake switch signal (see page 11-165)
. Fast idlethermovalve (see page'11 168)
. Hoses and connecttons. IAC valve and its mounting O-rings
lf the above items are normat, suDslitute a known-good IAC valve and readjust the idle speed {see page 11-169, 170)
lf the idle speed still cannot be adjusted to specification (and the scan tool does not indicate DTC P0505 or Pl508)
after IAC valve reolacement, substitute a known-good ECM/PCM and recheck lf symptom goes away' replace the
original ECM/PCM.
