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 com-
pletely 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-38, ªFuel Pressure Releaseº.
+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 crank-
shaft position sensor (POS) from the cylinder 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.
REMOVALNJEM0022S011. Drain coolant from radiator and cylinder block. Refer to LC-17,
ªChanging Engine Coolantº.
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.
Power steering oil pump does not need to be disconnected
from power steering tubes.

InspectionNJEM0088+Before inspecting the engine, make sure the engine has
cooled down; wait approximately 30 minutes after the engine
has been stopped.
+Visually inspect all belts for wear, damage, or cracks on con-
tacting surfaces and edge areas.
+When measuring deflection, apply 98 N (10 kg, 22 lb) at the.
marked point.
+When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning the crankshaft two turns or more, re-adjust to
the specified value to avoid variation in deflection
between pulleys.
+Tighten idler pulley lock nut by hand and measure deflec-
tion without looseness.
