INSTALLATION SERVICE POINTS
"AATHERMOSTAT INSTALLATION
Install the thermostat being careful not to fold over or scratch
the rubber ring.
Caution
Make absolutely sure that no oil is adhering to the rubber
ring of the thermostat. In addition, be careful not to fold
over or scratch the rubber ring when inserting. If the
rubber ring is damage, replace the thermostat.
"BARADIATOR UPPER HOSE CONNECTION
1. Insert each hose as far as the projection of the water
outlet fitting.
2. Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
INSPECTION
THERMOSTAT CHECK
1. Immerse the thermostat in water, and heat the water while
stirring. Check the thermostat valve opening temperature.
Standard value:
Valve opening temperature: 80±1.5_C
2. Check that the amount of valve lift is at the standard value
when the water is at the full-opening temperature.
Standard value:
Full-opening temperature: 93_C
Amount of valve lift: 9.5 mm or more
NOTE
Measure the valve height when the thermostat is fully
closed, and use this measurement to calculate the valve
height when the thermostat is fully open.

SRS -AirBagModuleandSeatBeltPre-tensioner
Disposal Procedures52B-65
Driver’s air bag module
(1) Remove the steering column cover, lower.
(Refer to GROUP 52A – Instrument Panel.)
(2) Disconnect the clock spring 2-pin connector and
instrument panel wiring harness connector (2-pin,
yellow).
NOTE
Once disconnected from the instrument panel wiring
harness, both electrodes of the clock spring connector
short automatically. This prevents the driver’s air bag
from accidental deployment caused by static, etc.
(3) Connect deployment harnesses longer than 6 m to
each SRS air bag adapter harness and insulate the
connections with plastic tape.
Also, connect the deployment harnesses in the other
ends to short, thereby preventing the driver’s air bag
from accidental deployment caused by static etc.
(4) Connect the SRS air bag adapter harness to the
clock spring 2-pin connector and route the deployment
harnesses out of the vehicle.
(5) Close all the doors with the windows fully closed and
put a cover over the vehicle to minimize report.
Caution
The cover is required as the glass, if already
damaged, may break.
(6) Separate the deployment harnesses as far from the
vehicle as possible and connect to the terminals of the
battery removed from the vehicle. Then deploy.
Caution
1) Before deploying the air bag, see that no one is in
and near the vehicle. Also, put on safety glasses.
2) The deployment makes the inflator of the
driver’s air bag very hot. Before handling the
inflator, wait more than 30 minutes for cooling.
3) If the driver’s air bag module fails to deploy
although the procedure is respected, do not go
near the module. Contact your local distributor.
(7) Discard the deployed air bag module according to
Deployed Air Bag Module Disposal Procedures.
(Refer to P.52B-75.)

(6) Separate the deployment harnesses as far from the
vehicle as possible and connect to the terminals of the
battery removed from the vehicle. Then deploy.
Caution
1) Before deploying the air bag, see that no one is
in and near the vehicle. Also, put on safety
glasses.
2) The deployment makes the inflator of the front
passenger’s air bag very hot. Before handling
the inflator, wait more than 30 minutes for
cooling.
3) If the front passenger’s air bag module fails to
deploy although the procedure is respected,
do not go near the module. Contact your local
distributor.
(7) Discard the deployed air bag module according to
Deployed Air Bag Module Disposal Procedures.
(Refer to P.52B-75.)
Seat belt pre-tensioner
(1) Remove the center pillar lower trim.
(Refer to GROUP 52A - Instrument Panel.)
(2) Disconnect the seat belt pre-tensioner 2 - pin
connector (red) from the floor wiring harness
connector (2 - pin, red).
NOTE
Once disconnected from the floor wiring harness, both
electrodes of the seat belt pre-tensioner connector
short-circuit automatically. This prevents the seat belt
pre-tensioner from accidental deployment caused by
static, and etc.
(3) Connect deployment harnesses longer than 6 m to
each SRS air bag adapter harness and insulate the
connections with plastic tape.
Also, connect the deployment harnesses in the other
ends to short, thereby preventing the seat belt
pre-tensioner from accidental deployment caused by
static etc.
(4) Connect the SRS air bag adapter harness to the
seat belt pre-tensioner 2 - pin connector (red) and pull
out the operation harness.

Caution
The cover is required as the glass, if already
damaged, may break.
(6) Separate the deployment harnesses as far from the
vehicle as possible and connect to the terminals of
the battery removed from the vehicle. Then deploy.
Caution
1) Before operating the seat belt pre-tensioner,
see that no one is in or near the vehicle.
2) The operation makes the insulator of the seat
belt pre-tensioner very hot. Before handling
the inflator, wait more than 30 minutes for
cooling.
3) If the seat belt pre-tensioner fails to operate
although the procedure is respected, do not go
near the seat belt pre-tensioner. Contact your
local distributor.
(7) Discard the operated seat belt pre-tensioner accord-
ing to Disposal Procedure. (Refer to P.52B-75.)
DEPLOYMENT OUTSIDE THE VEHICLE
Caution
1. Carry out air bag deployment or seat belt pre-tensioner
operation on large flat place at least 6 m away from any
object or person.
2. Avoid a strong wind weather when carrying out
deployment or operation outside the vehicle. Ignite the
air bag at a place upwind from the air bag module and
the seat belt pre-tensioner even in a breeze weather.
1. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds before any further job after the
disconnection of the battery cables. (Refer to P.52B-3.)
2. Carry out deployment of the air bag module and operation
of the seat belt pre-tensioner according to the following
procedure.
Driver’s side air bag module
type>
(1) Remove the driver’s air bag module from the vehicle.
(Refer to P.52B-52.)
Caution
Once disconnected, both electrodes of the driver’s air
bag module connector short automatically to prevent
accidental deployment caused by static etc. Still, in
consideration of the accidental deployment, store the
air bag module on flat place with deployment surface
facing up. Also, do not put anything on it.

(7) Separate the deployment harnesses as far from the
driver’s side air bag module as possible and connect
to the terminals of the battery removed from the
vehicle. Then deploy.
Caution
1) Before the deployment, see that no one is near
around the driver’s air bag module.
2) The deployment makes the inflator of the
driver’s air bag very hot. Before handling the
inflator, wait more than 30 minutes for cooling.
3) If the driver’s air bag module fails to deploy
although the procedure is respected, do not go
near the module. Contact your local
distributor.
(8) Discard the deployed air bag module as specified
in Deployed Air Bag Module Disposal Procedures.
(Refer to P.52B-75.)
Driver’s side air bag module
type>
(1) Remove the steering wheel - air bag module assembly
from the vehicle. (Refer to P.52B-52.)
Caution
Once disconnected, both electrodes of the driver’s
air bag module connector short automatically to
prevent accidental deployment caused by static
etc. Still, in consideration of the accidental
deployment, store the air bag module on flat place
with deployment surface facing up. Also, do not
put anything on it.
(2) Prepare two deployment harnesses longer than 6 m
for deployment and connect the terminals in one end
to short-circuit. This is to prevent accidental
deployment caused by static etc.
(3) Touch the vehicle’s body with bare hands to discharge
static in you.
Caution
Never fail to do Step (3) in order to prevent
accidental deployment caused by static.
