EXHAUST MANIFOLD AND TURBOCHARGER ASSEMBLY

1. Refer to the figure and install the gasket (1) to the cylinder head

(2).

2. Tighten nuts in the numerical order shown in the figure.

CAUTION:

Nuts 1, 4 - 8 do not have washers. Because 2 and 3 are nuts

with washers, be careful of the installation positions.

NOTE:

Nuts 9 - 12 indicate the second tightening.

3. Install removed parts in the reverse order of removal.

CAUTION:

After the exhaust manifold and turbocharger assembly is replaced, perform fully-closed position

learning for the wastegate valve, and use CONSULT to individually check the functions of the tur-

bocharger system. Refer to

EC-755, "Work Procedure"

(fully-closed position learning for waste

gate valve) and

EC-932, "Component Function Check"

(individual function inspection).

Inspection

INFOID:0000000012197427

INSPECTION PROCEDURE

Turbocharger Trouble Diagnosis [Oil Leakage, Smoke (white/blue), Lack of Power, Poor Acceleration, Unusual
Noise]

Check items before trouble diagnosis
1. Check that the engine oil amount is the specified level.
2. Interview the customer about whether the engine oil is cooled down by idling after driving.

Diagnosis

• Refer to the table below and check each of the parts.

• For the inspection methods, refer to "INSPECTION AFTER REMOVAL."

INSPECTION AFTER REMOVAL

Perform the following checks. If any adhering material is found, perform cleaning. If any irregularities are

found, or if the value is outside the standard, replace the exhaust manifold and turbocharger assembly.

• Refer to the figure for the names of parts and the locations for visual inspection.

• If the compressor wheel, turbine wheel, rotor shaft, or other internal part is damaged, check the following

paths and completely remove all fragments and other foreign material for preventing secondary malfunc-

tions.

Cleaning Work

NOTE:

The following explanatory figure shows an image of the inspection procedure. (The shapes in the figure do not

match the actual vehicle parts.)

• Clean before checking.

- Use engine conditioner (A) to clean the oil feed and return ports.

- Use radiator cleaner to clean the water feed and return ports.

• After cleaning, air-blow using an air gun (A).

• Air-blow the compressor wheel, turbine wheel, compressor hous-

ing, and turbine housing.

Compressor wheel

Inside of intake port is badly stained with
oil.

There are marks from rubbing against
housing.

Vane is bent or broken.

Rotor shaft

Heavy feel or catching when turned by
hand.

Cannot be turned by hand.

Excessively loose bearing.

Oil return port

Carbon or sludge deposit in oil drain port.

Highly possible.

Possible.

May exist.

EXHAUST MANIFOLD AND TURBOCHARGER ASSEMBLY

Turbine Wheel and Compressor Wheel

• Check visually, and by other means, for adhering oil.

• Check visually, and by other means, for adhering carbon.

• Check for bent or broken vanes.

• Check for interference with the housing.

Rotor Shaft

• Rotate rotor shaft (A) by hand and check that it turns smoothly

without resistance or sticking.

• Shake rotor shaft (A) vertically and horizontally and check for

looseness.

Mounting Surface Distortion

• Using a thickness gauge (A) and straightedge (B), check for distor-

tion of the exhaust manifold and turbocharger assembly mounting

surface at each port, and for distortion of the overall assembly.

• Replace exhaust manifold and turbocharger assembly if the limit is

exceeded.

INSPECTION AFTER INSTALLATION

Start the engine and increase the engine speed. Check for engine oil leakage, exhaust gas leakage, and cool-

ant leakage.

TIMING CHAIN

a. Secure crankshaft pulley (1) using a pulley holder (commercial

service tool) (A).

CAUTION:

• When securing the pulley holder, use a piece of wood or

an equivalent so that the pulley holder does not contact

any surrounding parts.

• Secure the pulley holder so that it is located at a right

angle to the crankshaft pulley.

b. Loosen and pull out crankshaft pulley bolts.

CAUTION:

Never remove the crankshaft pulley bolts as they are used as a supporting point for the pulley

puller.

Install M6 bolt (pitch: 1.0) to the thread hole of crankshaft pulley.

NOTE:

M6 bolts with a length under head of approximately 60 – 80

mm (2.36 – 3.15 in) are recommended.

d. Pull out crankshaft pulley (1) using a pulley puller [SST:

KV11103000 ( — ) ] (A).

5. Remove oil pan (lower). Refer to

EM-200, "Removal and Installation"

NOTE:

When the crankshaft sprocket and the oil pump drive component are not removed, this procedure is not

necessary.
