able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
For supporting points for lifting and jacking point at rear axle, refer to GI-48, "
Garage Jack and
Safety Stand and 2-Pole Lift".

Protect connectors using a resin bag to protect against foreign materials during the operation.
17. Disconnect fuel feed hose at engine side. Refer to EM-162, "
Component".
18. Disconnect heater hoses, and install plugs them to prevent engine coolant from draining. Refer to CO-47,

During the removal operation, always be careful to prevent the vehicle from falling off the lift due
to changes in the center of gravity.
If necessary, support the vehicle by setting jack or suitable tool at the rear.
During operation, securely support the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely support the engine slingers with a hoist.
