REMOVAL
Outline
At first, remove engine and transmission assembly with front suspension member from vehicle downward.
Then separate engine from transmission.
Preparation
1. Release fuel pressure. Refer to EC-79, "FUEL PRESSURE RELEASE" .
2. Drain engine coolant from radiator. Refer to CO-10, "
Changing Engine Coolant" .
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belts.
3. Disconnect both battery cables. Refer to SC-4, "
BATTERY" .
4. Remove the following parts:
Tower bar: Refer to FSU-20, "TOWER BAR" .
Engine cover: Refer to EM-17, "INTAKE MANIFOLD COLLECTOR" .
Cowl top cover (RH): Refer to EI-20, "COWL TOP" .
Undercover
Drive belts: Refer to EM-12, "DRIVE BELTS" .
Front road wheels and tires
5. Remove air cleaner case and air duct. Refer to EM-15, "
AIR CLEANER AND AIR DUCT" .
6. Discharge refrigerant from A/C circuit. Refer to ATC-123, "
REFRIGERANT LINES" .
7. Remove radiator cooling fan assembly, reservoir tank and hoses. Refer to CO-21, "
COOLING FAN" and
CO-13, "
RADIATOR" .
Engine Room
1. Disconnect heater hose at engine-side, and fit a plug onto hose end to prevent engine coolant leak.
2. Disconnect ground cable (between vehicle to left cylinder head).
3. Disconnect battery positive cable harness at vehicle side and temporarily fasten it on engine.
4. Disconnect A/C piping from A/C compressor, and temporarily fasten it on vehicle with a rope.
5. Remove engine room harness connectors as shown in the fig-
ure.
6. Disconnect two body ground cables.
7. Disconnect brake booster vacuum hose.
8. Disconnect fuel feed hose (with damper) and EVAP hose. Refer to EM-34, "
FUEL INJECTOR AND FUEL
TUBE" .
CAUTION:
Fit plugs onto disconnected hoses to prevent fuel leak.
9. Remove reservoir tank of power steering oil pump, and piping from vehicle, and temporarily secure them
on engine.
CAUTION:
When temporarily securing, keep the reservoir tank upright to avoid a fluid leak.
Passenger Room Side
Follow procedure below to disconnect engine room harness connectors at passenger room side, and tempo-
rarily secure them on engine.
