b. Disconnect ignition coil and injector harness connectors. Refer to EM-49, "Exploded View" and EM-44,
"Exploded View".
3. Remove intake valve timing control solenoid valve. Refer to EM-79, "
Exploded View".
4. Crank engine, and then check that engine oil comes out from
intake valve timing control solenoid valve hole (A). End crank
after checking.
WARNING:
Be careful not to touch rotating parts. (drive belt, idler pul-
ley, and crankshaft pulley, etc.)
CAUTION:
 Prevent splashing by using a shop cloth so as to prevent
the worker from injury from engine oil and so as to prevent engine oil contamination.
 Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful no to apply engine oil to rubber parts of drive belt,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.
5. 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, and then clean it. Refer to LU-10, "
Removal and Installation".
 Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-2,
"EngineLubricationSystem".
6. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
 Clean oil groove if necessary. Refer to LU-2, "
EngineLubricationSystem".
7. After inspection, install removed parts in the reverse order.
Inspection for Leakage
The following are procedures for checking fluids leak, lubricates leak. Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
 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 check there is no leakage 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.

General Precautions".
REMOVAL
1. Check fuel level on fuel gauge. If fuel gauge indicates more than
the level as shown in the figure (full or almost full), drain fuel
from fuel tank until fuel gauge indicates level as shown in the fig-
ure or below.
NOTE:
Because fuel will be spilled when removing fuel level sensor
units for the top of the fuel is above the fuel level sensor units
installation surface.
• As a guide, fuel level becomes the position as shown in the
figure or below when approximately 10 (2-1/4 Imp gal) of
fuel are drained from fuel tank.
 In a case that fuel pump does not operate, perform the follow-
ing procedure.
a. Insert hose of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to draw
fuel from fuel filler tube.

PRECAUTIONS
 If old rubber hose is re-used, install hose clamp in its original posi-
tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.
 After installing plate clamps, apply force to them in the direction of
the arrow, tightening rubber hose equally all around.
Engine OilsINFOID:0000000003852785
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
 Avoid prolonged and repeated contact with oils, particularly used engine oils.
 Wear protective clothing, including impervious gloves where practicable.
 Do not put oily rags in pockets.
 Avoid contaminating clothes, particularly underpants, with oil.
 Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
 First aid treatment should be obtained immediately for open cuts and wounds.
 Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
 Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-
tions containing lanolin replace the natural skin oils which have been removed.
 Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
 If skin disorders develop, obtain medical advice without delay.
 Where practical, degrease components prior to handling.
 Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning pollution vary between regions.
Air ConditioningINFOID:0000000003852786
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to
HA section “REFRIGERATION SYSTEM” for specific instructions.
