WARNING:
+Situate 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.
+Be sure to hoist engine and transmission in a safe man-
ner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATA-
LOG.
CAUTION:
+When lifting engine, be careful not to strike adjacent
parts, especially the following: Accelerator wire casing,
brake lines, and brake master cylinder.
+In hoisting the engine, always use engine slingers in a
safe manner.
+For 4WD models, apply sealant between engine and
transmission. Refer to MT section (ªRemoval and Instal-
lationº).
+For tightening torque, refer to M/T and PD sections.
+Before separating engine and transmission, remove the
crankshaft position sensor (TDC sensor) from the
assembly.
+Always pay extra attention not to damage edge of crank-
shaft position sensor (TDC sensor) or ring gear teeth.
