(7)Disconnect the bank 2 CMP sensor connector(A) and the ECT(Engine Coolant Temperature) sensor
connector(B).
(8)Disconnect the bank 2 front/rear O2 sensor connectors(A,B) and the CKP sensor connector(C).
(9)Disconnect the bank 1 CMP sensor connector(A).
7.Remove the PCV(Pulge Control Valve) hose(A).

(2)Connect the breather hose(B) from air cleaner hose.
(3) Connect the MAF connector(A).
26. Install the engine cover.
27. Refill engine coolant.
DISASSEMBLY
Identify MLA(Mechanical Lash Adjuster), valves and valve springs as they are removed so that each item can be
reinstalled in its original position.
1. Remove MLA(Mechanical Lash Adjuster)s(A).
2.Remove valves.
(1) Using SST(09222- 3K000, 09222 - 3C300), compress the valve spring and remove retainer lock.
(2)Remove the spring retainer.
(3) Remove the valve spring.
(4) Remove the valve.

5.Remove the under cover.
6.Drain the engine coolant.
7. Remove the upper radiator hose(A) and lower radiator hose(B).
8.Remove the transaxle oil cooler hoses(A/T vehicles only).
9. Remove the fuel inlet hose(A) from the delivery pipe.
10. Disconnect the engine wiring harness connectors.

INSTALLATION
Installation is in the reverse order of removal.
Perform the following :a. Adjust the shift cable.
b. Refill the engine with engine oil.
c. Refill the transaxle with fluid.
d. Refill the radiator with engine coolant.
e. Bleed air from the cooling system with the heater valve open.
f. Clean the battery posts and cable terminals with sandpaper assemble them, then apply grease to prevent
corrosion.
g. Inspect for fuel leakage.
After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for
approximately two seconds and fuel line pressurizes.
Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.

REMOVAL
WATER PUMP
1. Drain the engine coolant.
System is under high pressure when the engine is hot. To avoid danger of releasing scalding engine coolant,
remove the cap only when the engine is cool.
2. Remove drive belt(A).
3.Remove the timing belt.
4. Remove the water pump(A) and gasket(B).
WATER TEMPERATURE CONTROL ASSEMBLY
1.Drain the engine coolant.
2. Remove the air cleaner assembly.
3. Disconnect the radiator upper and lower hose(A, B).

4.Disconnect the ECT(Engine Coolant Temperature) sensor connector.
5. Remove the coolant hose related to the heater hoses and the ECT(Engine Coolant Temperature) system.
6. Remove wiring protector.
7. Remove water temperature control assembly(A) and the gaskets(B).
8.Remove the water pipe(A).
THERMOSTAT
Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency. Do not remove
the thermostat, even if the engine tends to overheat.
1. Drain engine coolant so its level is below thermostat.
2. Remove the coolant inlet pitting(A) and the thermostat(B).

RADIATOR
1.Drain the engine coolant.
2. Remove the radiator grille upper cover(A).
3.Remove the radiator support upper member assembly(A) for convenience sake.
The bottom side bolt(A) which can be seen after removing the under cover should be loosened for removal of
the radiator support upper member assembly.

Clean the contacting face before assembling.
2. Install the timing belt.
3. Install drive belt(A).
4.Fill with engine coolant.
5. Start engine and check for leaks.
6. Recheck engine coolant level.
WATER TEMPERATURE CONTROL ASSEMBLY
1.Install the water pipe(A).
Tightening torque
16.7 ~ 19.6Nm (1.7 ~ 2.0kgf.m, 12.3 ~ 14.5lb- ft)
2.Install the water temperature control assembly(A) with a new gasket(B).
Tightening torque

29.4 ~ 41.2Nm(3.0 ~ 4.2kgf.m, 21.7 ~ 30.4lb- ft
Use new O - rings and wet them with water or coolant when reassembling.
3. Install the wiring protector.
4. Connect the heater hose and ECT hose.
5. Connect the ECT sensor connector.
6. Connect the radiator upper and the lower hose(A).
7.Install the air cleaner assembly.
8. Fill with engine coolant.
9. Start engine and check for leaks.
10. Recheck engine coolant level.
THERMOSTAT
1.Place thermostat(B) in coolant inlet pitting(A).
Install the thermostat with the jiggle valve upward.

2.Install the coolant inlet pitting(A).
Tightening torque
16.66 ~ 19.60Nm (1.7 ~ 2.0kgf.m, 12.30 ~ 14.47lb- ft)
3. Fill with engine coolant.
4. Start engine and check for leaks.
RADIATOR
1.Install the radiator fan(A) to the radiator.
Tightening torque
4.9 ~ 7.8Nm (0.5 ~ 0.8kgf.m, 3.6 ~ 5.8lb - ft)
2. Install the radiator assembly to the vehicle.
3. Fix the condenser with the radiator assembly.
Tightening torque
4.9 ~ 7.8Nm (0.5 ~ 0.8kgf.m, 3.6 ~ 5.8lb - ft) - D
