REMOVAL SERVICE POINTS



A



POWER STEERING OIL PUMP REMOVAL

Remove the power steering oil pump from the engine with
the hose attached.

NOTE
Place the removed power steering oil pump where it will not
be a hindrance when removing and installing the engine
assembly, and tie it with a cord.



B



A/C COMPRESSOR REMOVAL

Disconnect the A/C compressor connector and remove the
compressor from the compressor bracket with the hose still
attached.

NOTE
Place the removed A/C compressor where it will not be a
hindrance when removing and installing the engine assembly,
and tie it with a cord.

ENGINE MOUNT BRACKET REMOVAL

1.

Support the engine with a garage jack.

2.

Remove the mechanical hanger (recommended tool) which
was attached when the transmission assembly was
removed.

3.

Hold the engine assembly with a chain block or similar
tool.

4.

Place a garage jack against the engine oil pan with a
piece of wood in between, jack up the engine so that
the weight of the engine is no longer being applied to
the engine mount bracket, and then remove the engine
mount bracket.



D



ENGINE ASSEMBLY REMOVAL

After checking that all cables, hoses and harness connectors,
etc., are disconnected from the engine, lift the chain block
slowly to remove the engine assembly upward from the engine
compartment.

piece of wood in between, and install the engine mount
bracket while adjusting the position of the engine.

2.

Support the engine with the garage jack.

3.

Remove the chain block and support the engine assembly
with the mechanical hanger (recommended tool).

O-RING/HIGH-PRESSURE FUEL HOSE
INSTALLATION

1.

Apply a small amount of new engine oil to the O-ring.

Caution
Do not let any engine oil get into the delivery pipe.

2.

While turning the high-pressure fuel hose to the right and
left, install the delivery pipe, while being careful not to
damage the O-ring. After installing, check that the hose
turns smoothly.

3.

If the hose does not turn smoothly, the O-ring is probably
being clamped. Disconnect the high-pressure fuel hose
and check the O-ring for damage. After this, re-insert the
delivery pipe and check that the hose turns smoothly.

4.

Tighten to the specified torque.

Specified torque: 5.0 Nm
