Removal and Installation (AWD Model)
WARNING:
^ Situate vehicle on a flat and solid surface.
^ Place chocks AT front and back of rear wheels.
^ For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS CATALOG.
CAUTION:
^ Always be careful to work safely, avoid forceful or uninstructed operations.
^ Do not start working until exhaust system and engine coolant are cool enough.
^ If items or work required are not covered by the engine section, refer to the applicable sections.
^ Always use the support point specified for lifting.
^ Use either 2-point lift type or separate type lift as best you can. If board-on type is used for unavoidable reasons, support at rear axle jacking point with 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 "Garage Jack and Safety Stand".

3. Disengage intermediate fixing point. Pull out engine room harnesses to engine room side, and temporarily secure them on engine.
CAUTION:
^ When pulling out harnesses, take care not to damage harnesses and connectors.
^ After temporarily securing, cover connectors with vinyl or similar material to protect against foreign material adhesion.
Vehicle Underbody
1. Remove exhaust front tube. Refer to "EXHAUST SYSTEM".
2. Disconnect steering lower joint at power steering gear assembly side, and release steering lower shaft. Refer to "STEERING COLUMN".
3. Remove propeller shaft. Refer to "REAR PROPELLER SHAFT".
4. Disengage A/T control rod at control device assembly. Then, temporarily secure it on transmission, so that it does not sag. Refer to "SHIFT CONTROL SYSTEM".
5. Remove rear plate cover from oil pan (upper). Then, remove bolts fixing drive plate to torque converter. Refer to "TRANSMISSION ASSEMBLY"
6. Remove bolts fixing transmission to lower rear side of oil pan (upper). Refer to "TRANSMISSION ASSEMBLY"
7. Remove LH and RH side outer socket ends from steering knuckle. Refer to "FRONT SUSPENSION ASSEMBLY".
8. Remove lower ends of LH and RH side struts from lower arms. Refer to "FRONT SUSPENSION ASSEMBLY".
9. Remove LH and RH side lower arms from suspension member. Refer to "FRONT SUSPENSION ASSEMBLY".
10. Remove LH and RH side front drive shafts from LH and RH side steering knuckles. Refer to "FRONT DRIVE SHAFT".
Removal Work
1. Use a manual lift table caddy (commercial service tool) or equivalently rigid tool such as a transmission jack. Securely support bottom of suspension member and transmission.
CAUTION: Put a piece of wood or something similar as the supporting surface, secure a completely stable condition.
2. Remove rear engine mounting member bolt.
3. Remove suspension member mounting bolt and nut. Refer to "FRONT SUSPENSION ASSEMBLY".
4. Carefully lower jack to remove engine, transmission, and suspension member assembly. When performing work, observe the following:
CAUTION:
^ Confirm there is no interference with vehicle.
^ Make sure that all connection points have been disconnected.
^ Keep in mind the center of vehicle gravity changes. If necessary, use jack(s) to support vehicle at rear jacking point(s) to prevent it from falling it off the lift.
Separation Work
1. Install engine slingers into the front of RH bank cylinder head and the rear of left bank cylinder head.
Slinger bolts: 28.0 Nm (2.9 kg-m, 21 ft. lbs.)
^ To protect rocker cover against damage caused by tilting of engine slinger, insert spacer between cylinder head and engine rear lower slinger, in the direction shown in the figure.
NOTE: Spacer is a component part of engine rear upper slinger assembly.
2. Remove power steering oil pump from engine side. Refer to "POWER STEERING OIL PUMP".
3. Remove engine mounting insulator (RH and LH) under side nuts with power tool.
4. Lift with hoist and separate engine and transmission assembly from suspension member.
CAUTION:
^ Before and during this lifting, always check if any harnesses are left connected.
^ Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
5. Remove front drive shaft (LH and RH). Refer to "FRONT DRIVE SHAFT".
6. Remove alternator. Refer to "CHARGING SYSTEM".
7. Remove starter motor. Refer to "STARTING SYSTEM".
8. Remove front propeller shaft from front final drive assembly side. Refer to "FRONT PROPELLER SHAFT".
9. Separate engine from transmission assembly. Refer to "TRANSMISSION ASSEMBLY".

11. Remove dynamic damper, engine mounting insulator (rear) and rear engine mounting member from transmission.
12. Remove front final drive assembly from oil pan (upper). Refer to "FRONT FINAL DRIVE ASSEMBLY".
INSTALLATION
Note to the following, and install in the reverse order of removal.
^ For a location with a positioning pin, insert it securely into hole of mating part.
^ For a part with a specified installation orientation, refer to component figure in "Removal and Installation (AWD Model)".
^ When installing engine mounting bracket (LH and RH side) on cylinder block, tighten two upper bolts (shown as A in the figure) first. Then tighten two lower bolts (shown as B in the figure).
^ Install engine mounting bracket (RH) (Lower).
CAUTION: Tighten mounting bolts to the specified torque with following mounting surfaces touched.
^ Engine mounting bracket (RH) (Upper) to engine mounting bracket (RH) (Lower) (shown as C and D in the figure).
^ Front final drive assembly to engine mounting bracket (RH) (Lower) (shown as E in figure).
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
^ Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to "RECOMMENDED FLUIDS AND LUBRICANTS".
^ Use procedure to check for fuel leakage.
^ Turn ignition switch "ON" (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
^ Start engine. With engine speed increased, check again for fuel leakage at connection points.
^ Run engine to check for unusual noise and vibration.
^ Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids including engine oil and engine coolant.
^ Bleed air from lines and hoses of applicable lines, such as in cooling system.
^ After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
