1. DRAIN ENGINE COOLANT FROM RADIATOR
HINT:
It is not necessary to drain out all the coolant.
2. REMOVE ECT SWITCHES
(a) Disconnect the connector.

tween the terminals when the coolant temperature is
above 93°C (199°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
83°C (181°F).
If no continuity exists, replace the switch.
4. 1MZ±FE engine:
INSPECT No. 1 SWITCH CONTINUITY
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminals when the coolant temperature is
above 98°C (208°F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
88°C (190°F).
If no continuity exists, replace the switch.

HOW TO USE THIS MANUAL
To assist you in finding your way through the manual, the Section Title and major heading are given
at the top of every page.
PREPARATION
Preparation lists the SST (Special Service Tools), recommended tools, equipment, lubricant and SSM
(Special Service Materials) which should be prepared before beginning the operation and explains the
purpose of each one.
REPAIR PROCEDURES
Most repair operations begin with an overview illustration. It identifies the components and shows how
the parts fit together.
Example:
IN002±0W

INTRODUCTIONHOW TO USE THIS MANUAL ±

The procedures are presented in a step±by±step format:

The illustration shows what to do and where to do it.

The task heading tells what to do.

The detailed text tells how to perform the task and gives other information such as specifications
and warnings.
Example:
This format provides the experienced technician with a FAST TRACK to the information needed. The
upper case task heading can be read at a glance when necessary, and the text below it provides de-
tailed information. Important specifications and warnings always stand out in bold type.
REFERENCES
References have been kept to a minimum. However, when they are required you are given the page
to refer to.
SPECIFICATIONS
Specifications are presented in bold type throughout the text where needed. You never have to leave

CAUTIONS, NOTICES, HINTS:

CAUTIONS are presented in bold type, and indicate there is a possibility of injury to you or other
people.

NOTICES are also presented in bold type, and indicate the possibility of damage to the compo-
nents being repaired.

HINTS are separated from the text but do not appear in bold. They provide additional information
to help you perform the repair efficiently.
SI UNIT
The UNITS given in this manual are primarily expressed according to the SI UNIT (International System
of Unit), and alternately expressed in the metric system and in the English system.

GENERAL REPAIR INSTRUCTIONS
1. Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
2. During disassembly, keep parts in the appropriate order
to facilitate reassembly.
3. Observe the following:
(a) Before performing electrical work, disconnect the
negative (±) terminal cable from the battery.
(b) If it is necessary to disconnect the battery for inspec-
tion or repair, always disconnect the cable from the
negative (±) terminal which is grounded to the ve-
hicle body.
(c) To prevent damage to the battery terminal post, loos-
en the terminal nut and raise the cable straight up
without twisting or prying it.
(d) Clean the battery terminal posts and cable terminals
with a clean shop rag. Do not scrape them with a file
or other abrasive objects.
(e) Install the cable terminal to the battery post with the
nut loose, and tighten the nut after installation. Do
not use a hammer to tap the terminal onto the post.
(f) Be sure the cover for the positive (+) terminal is prop-
erly in place.
4. Check hose and wiring connectors to make sure that they
are secure and correct.
5. Non±reusable parts
(a) Always replace cotter pins, gaskets, O±rings and oil
seals etc. with new ones.
(b) Non±reusable parts are indicated in the component
illustrations by the ºº symbol.
6. Precoated parts
Precoated parts are bolts and nuts, etc. that are coated
with a seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(b) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then applyIN022±07

the specified seal lock adhesive to the bolt, nut or
threads.
(c) Precoated parts are indicated in the component il-
lustrations by the º
º symbol.
7. When necessary, use a sealer on gaskets to prevent
leaks.
8. Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
9. Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found at the preparation of AX section.
10. When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating.
11. To pull apart electrical connectors, pull on the connector
itself, not the wires.
12. Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations.
(a) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels at the opposite
end in order to ensure safety.
(b) After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on
a vehicle raised on a jack alone, even for a small job
that can be finished quickly.
