Use approved bonding agent, sealants or their equivalents when required.

Use tools and recommended special tools where specified for safe and efficient service repairs.

When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for All Mode 4 × 4 SystemEAS000GQ
Even if the 2WD mode is selected, the All mode 4 × 4 system occasionally changes from 2WD to 4WD auto-
matically depending on the driving conditions.
When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free
rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving
force from the rear wheels.
To avoid personal injury and vehicle damage, use one of the following methods when working with the front
wheels drive force and spinning freely.

Remove the propeller shaft.

Use free rollers / chassis dynamometer designed for 4WD vehicles.
Precautions for Three Way CatalystEAS000FR
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.

Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.

When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.

Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precautions for FuelEAS000P9
GASOLINE ENGINE
Use unleaded gasoline with an octane rating of at least 95 (RON).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
DIESEL ENGINE
Diesel fuel of at least 50 cetane.
If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper-
ature conditions.

Above –7°C (20°F) ... Summer type diesel fuel.

Below –7°C (20°F) ... Winter type diesel fuel.

REMOVAL
1. Remove ignition coil. Refer to EM-31, "IGNITION COIL" .
2. Remove spark plug with spark plug wrench (commercial service
tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL (EXCEPT RUSSIA)
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

Frequent engine starts

Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

Extended highway driving

Frequent high engine revolution

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-49, "
FUEL PRESSURE RELEASE" (WITH EURO-OBD) or EC-562,
"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Disconnect fuel pump fuse to avoid fuel injection during mea-
surement.
4. Remove ignition coil and spark plug from each cylinder. Refer to EM-31, "
IGNITION COIL" and EM-32,
"SPARK PLUG" .
5. Connect engine tachometer (not required in use of CONSULT-II).
6. Install compression tester with adapter onto spark plug hole.

Use the adapter whose picking up end inserted to spark plug
hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (bar, kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain specified engine speed.

NOTE:
Can be removed and installed even when assembled with cylinder head.
4. Remove front cover and timing chain. Refer to EM-46, "
TIMING CHAIN" .
5. Remove camshafts. Refer to EM-56, "
CAMSHAFT" .
6. Securely support bottom of cylinder block with a jack or equivalent tool, and release the hoist that was
supporting it.
7. Remove cylinder head loosening bolts in reverse order as
shown in the figure.

Using the following tool, loosen cylinder head bolts.
NOTE:
There are two types of cylinder head bolt because of parallel
manufacture.
8. Remove cylinder head gasket.
INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter

Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.

If reduction of outer diameter appears in a position other than
“d2”, use it as “d2” point.
NOTE:
When replacing any cylinder head bolts, it is possible to use them
with mixing flange bolt and bolt with washer.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checked. Refer to EM-110, "
CYLIN-
DER BLOCK DISTORTION" .
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for engine oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.

If it exceeds the limit, replace cylinder head.Bolt with washer

The shank length under the bolt neck above is the length of
threaded part (pilot portion not included).
e. After tightening all the bolts, re-tighten in the same order.
2. Install power steering oil pump.
3. Install fuel pump. Refer to EM-171, "
FUEL PUMP" .

Before installing, make sure that spacer and the hole 6 mm
(0.24 in) in diameter on coupling are aligned.
4. Install chain guide and tension guides.
5. Install crankshaft sprocket, aligning it with crankshaft key on the
far side.
6. Install primary timing chain with fuel pump sprocket.

When installing, match the alignment marks on sprockets with
color coded alignment marks (colored links) on primary timing
chain.

Install fuel pump sprocket washer with the surface marked “F”
(front mark) facing the front of the engine.
7. Install timing chain onto power steering oil pump sprocket and
through chain guide.
8. Use the positioning stopper pin (special service tool) to hold the
fuel pump sprocket and install the bolt.

Using the TORX wrench (special service tool), turn the fuel
pump shaft little by little to adjust the position of the fuel pump
sprocket. Insert positioning stopper pin into the hole 6 mm
(0.24 in) in diameter on fuel pump sprocket so that the stop-
per pin goes through the fuel pump body. While the stopper
pin is in place, install the bolt.16 mm (0.63 in) : Bolt No. 1, 2, 16, 17, 18, 19, 20, 21, 22
