ENGINE ASSEMBLY
• Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
• When installation directions are specified, install parts according to the directions. Refer to EM-191, "
Com-
ponent".
• Prior to installing the upper torque rod, apply a light coat of silicone lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
• Apply silicone lubricant (A) by dabbing the outward facing tube
surface with a sponge or suitable tool.
• Do not apply excess lubricant.
• Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
• Tighten engine mounting insulator (RH) bolts in the numerical order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases 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 MA-14
.
• 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, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ- ing 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.

CAUTION:
When removing fuel filler hose (1) at the fuel filler tube,
mark components for alignment.
10. Remove vent hose (1) and EVAP hose (2) at rear of fuel tank. • Disconnect vent hose and EVAP hose quick connectors using
the following procedures.
a. Pinch retaining tabs (A) of vent hose quick connector and remove vent hose (1).
b. Slide sleeve (B) of EVAP hose quick connector and remove EVAP hose (2).
• If hoses are stuck, push and pull several times until they movefreely, and disconnect.
CAUTION:
• The tube can be removed when the tabs are completely depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep the resin tube away from heat. Be especially careful when we lding near the tube.
• Prevent acid liquid such as battery electro lyte, from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Do not insert plug that may cause da mage to O-ring in quick connector.
• To keep the connecting portio n clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
11. Support center of fuel tank (1) with transmission jack (A). CAUTION:
Securely support the fuel tank with a suitable tool (B).
12. Remove fuel tank bands (RH and LH).
13. Lower transmission jack carefully to remove fuel tank while sup- porting it by hand.
CAUTION:

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
General PrecautionINFOID:0000000005399835
• Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or ot her enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
• Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent t he vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
• When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
• Before starting repairs which do not require battery power: Turn off ignition switch.
Disconnect the negative battery terminal.
• If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
• Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.
• To prevent serious burns: Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
• Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.
• Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
• Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

PRECAUTIONS
• Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
• After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.
• Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic tro uble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC, CVT, and AT sections.
Precaution for Three Way CatalystINFOID:0000000005399836
If a large amount of unburned fuel flows into the catalyst , the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
• Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
• When checking for ignition spark or measuring engine compression, make tests quickly and only when nec- essary.
• Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the
catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precaution for Fuel (Unleade d Regular Gasoline Recommended)INFOID:0000000005399837
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
