ENGINE ASSEMBLY
WARNING:
●Position vehicle on a flat and solid surface.
●Place chocks at front and back of rear wheels.
●Do not remove engine until exhaust system has completely cooled off, otherwise, you may burn
yourself and/or fire may break out in fuel line.
●Before disconnecting fuel hose, release pressure.
Refer to EC-34 (WITH EURO-OBD), EC-428 (WITHOUT EURO-OBD).
●Be sure to lift engine and transaxle in a safe manner.
●For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:
●When lifting engine, be sure to clear surrounding parts. Use special care near accelerator wire
casing, brake lines and brake master cylinder.
●When lifting the engine, always use engine slingers in a safe manner.
●When removing drive shaft, be careful not to damage grease seal of transaxle.
●Before separating engine and transaxle, remove crankshaft position sensor (POS) from the cylin-
der block assembly.
●Always be extra careful not to damage edge of crankshaft position sensor (POS), or signal plate
teeth.
Engine cannot be removed separately from transaxle. Remove engine with transaxle as an assembly.
REMOVAL
1. Drain coolant from radiator and cylinder block. Refer to LC-17, "Chacking Engine Coolant".
2. Remove coolant reservoir tank and bracket.
3. Drain engine oil.
4. Remove battery and battery tray.
5. Remove air cleaner and air duct.
6. Remove drive belts.
7. Remove alternator and air conditioner compressor from engine.
8. Remove power steering oil pump from engine and position aside.

Alternator
Alternator brackets
Radiator and cooling fan
Engine cover
Air ducts and air cleaner case
LH side of engine room:
4. Disconnect all harnesses and grounds that are connected to
components on vehicle.
5. Disconnect vacuum hose on vacuum pump side.
6. Disconnect fuel feed and fuel return hoses on engine side.
Immediately put blind plugs into the openings to prevent
fuel from flowing out.
7. Disconnect heater hose. Plug opening of hose to prevent cool-
ant from flowing out.
RH side of engine room:
8. Remove air conditioner compressor from brackets and move
it toward vehicle side. Secure compressor on vehicle side with
rope.
Vehicle underside:
9. Remove exhaust front tube.
10. Disconnect two hoses from power steering pump and plug to
stop fluid.
11. Remove M/T control rod and support rod.
12. Remove ABS wheel sensor, and temporarily hang brake cali-
per with rope on vehicle side.
13. Remove RH and LH drive shafts.

14. Install engine slingers to cylinder head.
: 30 - 37 N·m (3.0 - 3.8 kg-m, 22 - 27 ft-lb)
Use engine slingers and securing bolts of the specified
service parts.
15. Lift up vehicle to appropriate level where work can be per-
formed efficiently. Using two transmission jacks, securely sup-
port engine oil pan and bottom surface of transaxle.
