4. Remove cowl top extension. Refer to
EXT-24, "Removal and Installation".
5. Remove the front road wheel and tire (RH). Refer to WT-55, "Adjustment"
.
6. Remove the fender protector (RH). Refer to EXT-26, "FENDER PROTECTOR : Removal and Installation"
.
7. Drain coolant from the radiator. Refer to CO-36, "Changing Engine Coolant"
.
CAUTION:
Perform when the engine is cold.
8. Disconnect coolant reservoir hose and remove coolant reservoir tank. Refer to CO-40, "Exploded View"
.
9. Drain the power steering fluid reservoir. Refer to ST-30, "Draining and Refilling"
.
10. Remove the power steering oil pump. Refer to ST-38, "Removal and Installation"
.
11. Support engine and remove the RH engine insulator and bracket. Refer to EM-220, "Exploded View"
.
12. Set No. 1 cylinder at TDC on its compression stroke. • Align pointer with TDC mark on crankshaft pulley.
13. Remove drive belt. Refer to EM-134, "Removal and Installation"
.
14. Remove the drive belt auto-tensioner assembly. Refer to EM-135, "Removal and Installation of Drive Belt
Auto-tensioner".
15. Remove water drain plug (A) and copper sealing washer (B) to drain coolant from engine.
CAUTION:
Do not reuse copper sealing washers.
16. Disconnect RH valve timing control connectors and remo ve valve timing control cover (bank 1). Refer to
EM-182, "Exploded View"
.
17. Remove water pump cover. Refer to CO-44, "Exploded View"
.
18. Remove the timing chain tensioner (primary) as follows:
a. Pull the lever (C) down to release the plunger stopper tab (B).
b. Insert the stopper pin A into the tensioner body hole to hold the lever (C) and keep the plunger stopper tab (B) released.
NOTE:
An allen wrench [(1.2 mm (0.047 in)] is used for a stopper pin A
as an example.
c. Compress the plunger (D) into the tensioner body (1) by press- ing the slack guide (2).
d. Keep the slack guide (2) pressed and lock the plunger (D) in by pushing the stopper pin A through the lever (C) and into the
chain tensioner body hole.
e. Remove timing chain tensioner bolts and then remove the timing chain tensioner. CAUTION:
Be careful not to drop timing chain te nsioner bolts inside timing chain case.
19. Remove the three water pump bolts (A). Make a gap between water pump sprocket (1) and timing chain, by carefully turning
crankshaft pulley (2) counterclockwise until timing chain loosens
on water pump sprocket (1).

4. Turn the crankshaft pulley approximately 20
° clockwise so that
the timing chain on the timing chain tensioner side is loose.
5. Apply engine oil to the oil feed hole and timing chain tensioner and install the timing chain tensioner.
6. Remove the stopper pin (A).
7. Install valve timing control cover (bank 1) and water pump cover.
a. Before installing, remove all traces of liquid gasket from mating surface of water pump cover and IVT cover using a scraper.
Also remove traces of liquid gasket from the mating surface of the front cover.
b. Apply a continuous bead of liquid gasket to mating surface of IVT cover and water pump cover. Use Gen-
uine RTV Silicone Sealant or equivalent. Refer to GI-21, "Recommended Chemical Products and
Sealants".
CAUTION:
• Installation should be done within 5 minutes afte r applying liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after the co mponents are installed to allow
the sealant to cure.
8. Install water drain plug (A) and copper sealing washer (B). CAUTION:
Do not reuse copper sealing washers.
9. Installation of remaining components is in the reverse order of removal. • After installation, refill coolant and check for leaks. Refer to CO-36, "Changing Engine Coolant"
and CO-
35, "System Inspection".
CAUTION:
Do not spill coolant in en gine compartment. Use a sh op cloth to absorb coolant.
• After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to purge air from the high-pressure chamber of the chai n tensioner. The engine may produce a rattling noise.
This indicates that air still remains in the chamber and is not a matter of concern.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.

< PRECAUTION >[QR25DE]
PRECAUTIONS
• Be sure to connect rubber tubes properly afte
r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to the malfunction of the EVAP system or fuel injection system,
etc.
• Be sure to erase the unnecessary malfunction info rmation (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.
General PrecautionsINFOID:0000000009462050
•Always use a 12 volt battery as power source.
• Do not attempt to disconnect battery cables while engine is
running.
• Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
• Before removing parts, turn ig nition switch OFF and then dis-
connect battery ground cable.
• Do not disassemble ECM.
• If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slight ly when the terminal is dis-
connected. However, this is no t an indication of a malfunc-
tion. Do not replace parts b ecause of a slight variation.
• If the battery is disconnected, the following emission-related
diagnostic information will be lost within 24 hours.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
• When connecting or disconnect ing pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
• Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and co ndenser, thus resulting in dam-
age to ICs.
• Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to preven t engine control system mal-
functions due to receiving exter nal noise, degraded operation
of ICs, etc.
• Keep engine control system parts and harness dry.
• Before replacing ECM, perform ECM Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-88, "Reference Value"
.
• Handle mass air flow sensor carefully to avoid damage.
• Do not clean mass air flow senso r with any type of detergent.
• Do not disassemble electric throttle control actuator.
• Even a slight leak in the ai r intake system can cause serious
incidents.
• Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).
