Installation
Reverse removal procedure noting the following.
• Clean mating surfaces of ECT sensor and thermostat case.
• Check O-ring for damage and replace, if necessary.
• Tighten ECT sensor (1) to specified torque.
Tightening torque
ECT sensor (a): 15 N·m (1.5 kgf-m, 11.0 lb-ft)
• Connect connector to ECT sensor securely.
• Refill coolant referring to “Cooling System Flush and
Refill in Section 1F”.
ECT Sensor InspectionS7RS0B1306009
Immerse temperature sensing part of ECT sensor (1) in
water (or ice) and measure resistance between sensor
terminals while heating water gradually.
If measured resistance doesn’t show such characteristic
as shown, replace ECT sensor.
HO2S-1 and HO2S-2 Heater On-Vehicle
Inspection
S7RS0B1306010
1) Disconnect sensor connector.
2) Using ohmmeter, measure resistance between terminals “V
B” and “GND” of sensor connector.
If found faulty, replace oxygen sensor.
NOTE
Temperature of sensor affects resistance
value largely. Make sure that sensor heater is
at correct temperature.

Resistance of oxygen sensor heater
HO2S-1: 5.0 – 6.4 Ω at 20 °C (68 °F)
HO2S-2: 11.7 – 14.5 Ω at 20 °C (68 °F)
Viewed from terminal side
3) Connect sensor co nnector securely.
HO2S-1 and HO2S-2 Removal and InstallationS7RS0B1306011
Removal
WARNING!
To avoid danger of being burned, do not
touch exhaust system when system is hot.
Oxygen sensor removal should be performed
when system is cool.

1) Disconnect negative (–) cable at battery.
2) Disconnect connector of heated oxygen sensor and
release its wire harness from clamps.
3) Perform following items before removing heated oxygen sensor.
a) For HO2S-1, remove exhaust manifold referring to “Exhaust Manifold Remo val and Installation in
Section 1K”, if necessary.
b) For HO2S-2, hoist vehicle.
4) Remove heated oxygen sensor from exhaust pipe or exhaust manifold.

2) Install new seal ring and connect exhaust No.1 pipe (1) to exhaust manifold.
Tighten pipe fasteners to specified torque.
Tightening torque
Exhaust No.1 pipe bolt (a): 50 N·m (5.0 kgf-m,
36.5 lb-ft)
3) Install exhaust manifold stiffener (2). Tighten exhaust manifold stiffener bolts to specified
torque.
Tightening torque
Exhaust manifold stiffener bolt (b): 50 N·m (5.0
kgf-m, 36.5 lb-ft)
4) Install new seal ring and connect exhaust No.1 pipe (1) to exhaust No.2 pipe. Tighten pipe fasteners to
specified torque.
Tightening torque
Exhaust No.2 pipe bolt (c): 43 N·m (4.3 kgf-m,
31.0 lb-ft)
5) Install heated oxygen sensors (3) referring to “HO2S-1 and HO2S-2 Removal and Installation in
Section 1C”, if removed.
NOTE
Be sure to identify heated oxygen sensor
No.1 and No.2 by its connector color.

6) Connect heated oxygen sensor No.2 connector (1)
(connector color: green) and heated oxygen sensor
No.1 connector (2) (connector color: black), and then
fit coupler to br acket securely. 7) Install exhaust manifold cover to exhaust manifold.
8) Install A/C condenser to vehicle body for equipped
with A/C.
9) Install radiator referrin g to “Radiator Removal and
Installation in Section 1F” for equipped with A/C.
10) Install front bumper with fr ont grille by referring to
“Front Bumper and Rear Bumper Components in
Section 9K”.
11) Install engine cover.
12) Connect negative cable at battery.
13) Check exhaust system for exhaust gas leakage.
Exhaust Pipe and Muffler Removal and
Installation
S7RS0B1B06003
For replacement of exhaust pipe, be sure to hoist vehicle
and observe WARNING under “Exhaust System
Components” and the following.
CAUTION!
Exhaust manifold have three way catalytic
converter in it, it should not be exposed to
any impulse.
Be careful not to drop it or hit it against
something.

• Tighten bolts and nuts to specified torque when reassembling. Refer to “Exhaust System
Components”.
• After installation, start engine and check each joint of exhaust system for leakage.
