Removal
   
When removing the high pressure fuel pump, high pressure fuel pipe, delivery pipe, and injector, there may be injury caused by leakage of high pressure fuel. Therefore, do not attempt repairing immediately after the engine stops.
   
•
Use fender covers to avoid damaging painted surfaces.
•
To avoid damage, unplug the wiring connectors carefully while holding the connector portion.
   
Mark all wiring and hoses to avoid misconnection.
1.
Remove the engine cover.
(Refer to Engine And Transaxle Assembly - "Engine Cover")
2.
Remove the air duct.
(Refer to Intake And Exhaust System - "Air Cleaner")
3.
Remove the battery.
(Refer to Engine Electrical System - "Battery")
4.
Remove the engine room under cover and engine room RH side cover.
(Refer to Engine And Transaxle Assembly - "Engine Room Under Cover")
5.
Drain the engine coolant.
(Refer to Cooling System - "Coolant")
6.
Drain the engine oil.
(Refer to Lubrication System - "Engine Oil")
7.
Remove the air cleaner assembly.
(Refer to Intake And Exhaust System - "Air Cleaner")
8.
Remove the surge tank.
(Refer to Intake And Exhaust System - "Surge Tank")
9.
Remove the intake manifold.
(Refer to Intake And Exhaust System - "Intake Manifold")
10.
Remove the LH/RH cylinder head cover.
(Refer to Cylinder Head Assembly - "Cylinder Head Cover")
11.
Remove the drive belt.
(Refer to Timing System - "Drive Belt")
12.
Remove the idler.
(Refer to Timing System - "Idler")
13.
Remove the drive belt tensioner.
(Refer to Timing System - "Drive Belt Tensioner")
14.
Remove the crankshaft damper pulley.
(Refer to Timing System - "Crankshaft Damper Pulley")
15.
Remove the water pump.
(Refer to Cooling System - "Water Pump")
16.
Remove the lower oil pan.
(Refer to Lubrication System - "Oil Pan")
17.
Remove the engine mounting bracket.
(1)
Install the jack to the edge of the upper oil pan to support the engine.
   
Insert the rubber block between jack and upper oil pan.
(2)
Disconnect the engine ground cable (A).
Tightening torque :
10.8 ~ 13.7 N.m (1.1 ~ 1.4 kgf.m, 8.0 ~ 10.1 lb-ft)

(3)
Remove the engine mounting support bracket (A).
Tightening torque :
88.3 ~ 107.9 N.m (9.0 ~ 11.0 kgf.m, 65.1 ~ 79.6 lb-ft)

18.
Remove the timing chain cover (A).

   
Be careful not to damage the contact surfaces of cylinder block, cylinder head and timing chain cover.
Installation
1.
Install the timing chain cover.
(1)
The sealant locations on chain cover and on counter parts (cylinder head, cylinder block, and lower oil pan) must be free of engine oil and etc.
(2)
Before assembling the timing chain cover, the liquid sealant TB 1217H should be applied on the gap between cylinder head and cylinder block. The part must be assembled within 5 minutes after sealant was applied.
Bead width : 2.5 mm (0.1 in.)

(3)
Apply liquid sealant TB 1217H on timing chain cover. The part must be assembled within 5 minutes after sealant was applied.
Sealant should be applied without discontinuity.

   
•
Fill the T-joint area (6EA *) with sealant.
•
Apply sealant all around the dowel pin hole (2EA).
(4)
Install the new gasket (A) to the timing chain cover.

   
When installing the timing cover, take cautious not to take off applied sealant from the timing cover by contacting with other parts.
(5)
The dowel pins on the cylinder block and holes on the timing chain cover should be used as a reference in order to assemble the timing chain cover to be in exact position.
Tightening torque
A (16EA) :
18.6 ~ 21.6 N.m (1.9 ~ 2.2 kgf.m, 13.7 ~ 15.9 lb-ft)
B (2EA) :
24.5 ~ 26.5 N.m (2.5 ~ 2.7 kgf.m, 18.1 ~ 19.5 lb-ft)
C (2EA) :
58.8 ~ 68.8 N.m (6.0 ~ 7.0 kgf.m, 43.4 ~ 50.6 lb-ft)
D (3EA) :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

(6)
Running the engine or performing a pressure test should not be performed within 30 minutes of assembly.
2.
Install the other parts in the reverse order of removal.
   
•
Refill engine oil.
•
Clean the battery posts and cable terminals with sandpaper. Assemble and then apply grease to prevent corrosion.
•
Inspect for fuel leakage.
–
After assembling the fuel line, turn on the ignition switch (without operating the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes.
–
Repeat this operation two to three times, and then check for fuel leakage at any point on the fuel lines.
•
Refill radiator and reservoir tank with engine coolant.
•
Bleed air from the cooling system.
–
Start engine and let it run until it warms up. (Until the radiator fan operates 3 or 4 times.)
–
Turn off the engine and let it cool down. Check the level in the radiator, and add coolant if needed. This will allow trapped air to be released from the cooling system.
–
Put radiator cap on tightly, then run the engine again and check for leaks.
