ENGINE ASSEMBLY
 Place chocks at front and back of rear wheels.
 For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
 Always be careful to work safely, avoid forceful or uninstructed operations.
 Never start working until exhaust system and engine coolant are cool enough.
 If items or work required are not covered by the engine section, refer to the applicable sections.
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking point at rear axle, refer to GI-30, "
Garage Jack and
Safety Stand and 2-Pole Lift".

WARNING:
Read “General Precautions” when working on the fuel system. Refer to FL-2, "
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.

system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Three Way CatalystINFOID:0000000003852782
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.
Multiport Fuel Injection System or Engine Control SystemINFOID:0000000003852783
 Before connecting or disconnecting any harness connector for the
multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
 Before disconnecting pressurized fuel line from fuel pump to injec-
tors, be sure to release fuel pressure.
 Be careful not to jar components such as ECM and mass air flow
sensor.
HosesINFOID:0000000003852784
HOSE REMOVAL AND INSTALLATION
 To prevent damage to rubber hose, do not pry off rubber hose with
tapered tool or screwdriver.
 To reinstall the rubber hose securely, make sure that hose insertion
length and orientation is correct. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against hose
stopper.)
