Cylinder Heads

Installation (cont'd)

4. Install the cylinder heads on the cylinder block.

5. Tighten the cylinder head bolts sequentially in 2 or

3 steps.

Specified Torque:

76 N-m (7.8 kgf-m, 56 Ibf-ft)

NOTE:

We recommend using a beam-type torque wrench.

When using a preset-type torque wrench, be sure

to tighten slowly and not to overtighten.

If a bolt makes any noise while you are torquing

it, loosen the bolt and retighten it.

Apply engine oil to the bolt

threads.
6. Install the head cover gasket in the groove of the

cylinder head cover. Seat the recesses for the cam-

shaft first, then work it into the groove around the

outside edges.

NOTE:

Before installing the cylinder head cover gasket,

thoroughly clean the seal and the groove.

When installing, make sure the head cover gasket

is seated securely in the corners of the recesses

with no gap.

7. 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, reap-

ply liquid gasket after removing old residue.

After assembly, wait at least 30 minutes before

filling the engine with oil.

Apply liquid gasket to

the shaded areas.ProCarManuals.com

Troubleshooting

How to Read Flowcharts

A flowchart is designed to be used from start to final repair. It's like a map showing you the shortest distance. But beware:

if you go off the "map" anywhere but a "stop" symbol, you can easily get lost.

Describes the conditions or situation to start a troubleshooting flowchart.

Asks you to do something; perform a test, set up a condition etc.

Asks you about the result of an action, then sends you in the appropriate troubleshooting direction.

(bold type)
The end of a series of actions and decisions, describes a final repair action and sometimes directs you to

an earlier part of the flowchart to confirm your repair.

NOTE:

• The term "Intermittent Failure" is used in these charts. It simply means a system may have had a failure, but it checks

out OK at this time. If the Malfunction Indicator Lamp (MIL) on the dash does not come on, check for poor connections

or loose wires at all connectors related to the circuit that you are troubleshooting (see illustration below).

• Most of the troubleshooting flowcharts have you reset the Powertrain Control Module (PCM) and try to duplicate the

Diagnostic Trouble Code (DTC). If the problem is intermittent and you can't duplicate the code, do not continue through

the flowchart. To do so will only result in confusion and, possibly, a needlessly replaced PCM.

• "Open" and "Short" are common electrical terms. An open is a break in a wire or at a connection. A short is an acci-

dental connection of a wire to ground or to another wire. In simple electronics, this usually means something won't

work at all. In complex electronics (like PCM's), this can sometimes mean something works, but not the way it's sup-

posed to.

Does the voltage stay within

NO
Intermittent failure, system is OK

at this time. Check for poor con-

nections or loose wires at C444

(located behind right kick panel),

C610 (secondary HO2S (Sensor

2)) and
PCM.
The scan tool indicates Diagnostic Trouble Code (DTC) P0139: A slow response problem in the Secondary

Heated Oxygen Sensor (Secondary HO2S) (Sensor 2) circuit.

— The MIL has been reported on.

— DTC P0139 is stored.

Problem verification:

1. Do the PCM Reset Procedure.

2. Start the engine. Hold the

engine at 3,000 rpm with no

load (in Park or neutral) until

the radiator fan comes on.

3. Check the secondary HO2S

(Sensor 2) or output at 3,000

rpm with the scan tool.

Replace the secondary HO2S (Sen-

sor 2).

PCM Memory Setting

NOTE: The PCM reset procedure and disconnecting the

battery or the BACK UP RADIO (7.5 A) fuse cancels the

PCM memory for idle control. The following procedure

is needed after the PCM reset procedure and reconnect-

ing the battery or the BACK UP RADIO (7.5 A) fuse.

1. Start the engine. Hold the engine at 3,000 rpm with

no load (in Park or neutral) until the radiator fan

comes on.

2. Let the engine idle for approx. 5 minutes under the

following conditions:

• Transmission in Park or neutral

• A/C switch OFF

• Headlights OFF

• Rear defogger OFFProCarManuals.com
