WARNING:
IPosition vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.
IBefore disconnecting fuel hose, release pressure.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC
SERVICE PROCEDUREº).
IBe sure to lift engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
IWhen lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
IWhen lifting the engine, always use engine slingers in a
safe manner.
IWhen removing drive shaft, be careful not to damage
grease seal of transaxle.
IBefore separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
IAlways 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.
