Fitting guidelines



A 
Fitting the O-ring
Fit the O-ring into the O-ring groove at the end of the water inlet
pipe, and insert it into the water pump after moistening with water
the places where the O-ring will make contact with the water pump.
Caution
Ensure that absolutely no engine oil, or other type of grease,
gets onto the O-ring.

Remove the deliver pipe, with the injector and the fuel pressure
regulator intact.
Caution
When removing the delivery pipe, be careful not to drop the
injector.
Fitting guidelines



A 

Connecting the O-ring and the fuel high pressure hose
1. Apply a small quantity of fresh engine oil to the O-ring, and
insert it into the delivery pipe without damaging the O-ring.
2. Check that the high pressure hose can be turned smoothly. If it
cannot be turned smoothly there is a possibility that it is biting
into the O-ring, so remove the high pressure hose and check for
any damage to the O-ring. If the O-ring is undamaged, reinsert it
into the delivery pipe and check once more whether the hose
can be turned smoothly.
3. Tighten the mounting bolt to the specified torque.
Tightening torque: 5.0 ± 1.0 N·m

2HOW TO USE THIS MANUAL
How to Use this Manual
Range of description
This manual explains the service procedure for the engine after it has been removed from the vehicle. For information on
removing the engine from the vehicle, or "on-vehicle" servicing of the engine, please refer to the separate service manual for
the relevant vehicle model.
Understanding the description
Inspection
The manual only indicates inspection points where special tools or measuring devices are required. It does not mention general
visual checks, part cleaning requirements, and so on, but these must also be carried out as part of the actual service work.
Service sequence
(1) A component diagram is provided at the beginning of each section in order to give the reader a clear
understanding of where the various parts are installed.
(2) The numbers in the component diagram indicate the sequence of the service procedure. Tightening torques
are shown and non-reusable parts are indicated where appropriate
Removal sequence:The part numbers correspond to the numbers in the component diagram and indicate
the removal sequence.
Installation sequence:This is only shown if the parts cannot be installed in the reverse order to the removal
sequence.
Disassembly sequence: The numbers of the part names correspond to the symbols in the component
diagram and indicate the disassembly sequence.
Assembly sequence:This is only shown if the parts cannot be re-assembled in the reverse order to the
disassembly sequence.
Symbols for lubricants and sealants
Application points for lubricants and sealants are
indicated by special symbols (shown right) on the
component parts diagram or on the following page............... Grease
.............. Sealant or liquid gasket (FIPG)
.............. Brake fluid
.............. Engine oil
Types of service points
“Service point” notes are used to give a detailed
description of essential maintenance and service
points, standard values, procedures for using special
tools, and other important information at relevant
points in the service sequence. The different types
of “service point” are shown on the right-hand side.: Indicates that there is a removal or
disassembly service point
: Indicates that there is an installation or
assembly service point
: Indicates that the removal or disassembly
service point is described in the ’01-14G6
DOHC Engine Service Manual.
: Indicates that the installation or assembly
service point is described in the ’01-14G6
DOHC Engine Service Manual.
: Indicates that the removal or disassembly
service point is described in the ’03-14G6
