2. Install fuel injector (4) to fuel tube (1) with the following proce-
dure:
a. Insert clip (2) into clip groove (F) on fuel injector. • Insert clip so that protrusion (G) of fuel injector matches cut-
out (D) of clip.
CAUTION:
• Never reuse clip. Replace it with a new one.
• Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached. • Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion (B) of fuel tube matches
cut-out (C) of clip.
• Make sure that fuel tube flange (A) is securely fixed in flange
fixing groove (E) on clip.
c. Make sure that installation is complete by making sure that fuel injector does not rotate or come off.
3. Set fuel tube and fuel injector assembly at its position for installation on cylinder head. CAUTION:
Be careful not to let tip of injector nozzle interfere with other parts.
4. Tighten bolts in numerical order as shown.
5. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check on Fuel Leakage 1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, make sure there are no fuel leaks at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start the engine. With engine speed increased, make su re again that there are no fuel leaks at connection
points.
CAUTION:
Never touch the engine immediately after it is stopped, as the engine becomes extremely hot.

pump sprocket bolt.
CAUTION:
• Secure the oil pump shaft with the WAF part (A).
• Never loosen the oil pump sp rocket bolt by tightening the
oil pump drive chain.
5. Install chain tensioner (for oil pump) (1). 1. Fix the plunger at the most compressed position using a
stopper pin (A), and then install it.

INSPECTION AFTER INSTALLATION The following are procedures for chec king fluids leak, lubricates leak.
• 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 GI-42, " Recommended Chemical Product and Sealant " .
• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, or any oil/fluids including engine oil and
engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-638, " Diagnosis Pro-
cedure " (Type 1) or
EC-1153, " Diagnosis Procedure " (Type 2).
• Check when engine is cold so as to pr event burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-16, " Inspection " .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while checking.
a. Remove intake manifold. Refer to EM-141, " Component " .
b. Disconnect ignition coil and in jector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to EM-160, " Component " .

6. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End cranking after checking.
• Check engine oil leakage by oil amount adhered to the shop cloth inserted into the oil hole.
WARNING:
• Be careful not to touch rotating parts (drive be lts, idler pulley, and crankshaft pulley, etc.).
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engi ne oil contamination.
CAUTION:
• Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
• Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engi ne oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid valve oil hole of the cylinder head.
• Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-199, " Component " .
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-15 .
8. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-15 .

• Use the adapter whose picking up end inserted to spark plug hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
