out in fuel line.
lBefore disconnecting fuel hose, release fuel pressure.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC
SERVICE PROCEDUREº).
lBe sure to hoist engine and transmission in a safe man-
ner.
lFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATA-
LOG.
CAUTION:

Take special care near accelerator wire casing, brake
lines and brake master cylinder.
lIn hoisting the engine, always use engine slingers in a
safe manner.
lFor 4WD models, apply sealant between engine and
transmission. Refer to MT section (ªRemoval and Instal-
lationº).
Removal
