  3. Drain engine coolant from radiator. Refer to "DRAINING ".
    CAUTION:
    • Perform this step when engine is cold.
    • Never spill engine coolant on drive belt.
  4. Remove the following parts:
  5. Discharge refrigerant from A/C circuit. Refer to "COLLECTION AND CHARGE ".
  6. Remove radiator hoses (upper and lower). Refer to "EXPLODED VIEW ".

Engine Room LH

  1. Disconnect heater hose from vehicle-side, and fit a plug onto hose end to prevent engine coolant leakage.
  2. Disconnect A/C piping from A/C compressor, and temporarily fasten it on vehicle with a rope. Refer to "EXPLODED VIEW ".
  3. Disconnect brake booster vacuum hose.
  4. Disconnect ground cables.

Engine Room RH

  1. Disconnect battery positive cable vehicle side and temporarily fasten it on engine.
  2. Disconnect all clips and connectors of the engine room harness from engine back side.
  3. Disconnect fuel feed hose (with damper) and EVAP hose. Refer to "EXPLODED VIEW ".
    CAUTION: Fit plugs onto disconnected hoses to prevent fuel leakage.
  4. Remove reservoir tank of power steering oil pump and piping from vehicle, and temporarily secure them on engine. Refer to "AWD: EXPLODED VIEW ".
    CAUTION: When temporarily securing, keep the reservoir tank upright to avoid a fluid leakage.

Vehicle Inside

Follow procedure below to disconnect engine room harness connectors at passenger room side, and temporarily secure them on engine.

  1. Remove passenger-side kicking plate and dash side finisher. Refer to "EXPLODED VIEW ".
  2. Disconnect engine room harness connectors at unit sides TCM, ECM and other.
  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 A/T fluid cooler hoses and power steering oil pump oil cooler hoses.
    NOTE: Cap or plug opening(s) to prevent fluid from spilling.
  2. Disconnect heated oxygen sensor 2 harness. Refer to "REMOVAL AND INSTALLATION ".
  3. Remove three way catalyst and exhaust front tube. Refer to "EXPLODED VIEW ".
  4. Disconnect steering lower joint at power steering gear assembly side, and release steering lower shaft. Refer to "EXPLODED VIEW ".
  5. Remove rear propeller shaft. Refer to "EXPLODED VIEW ".
    NOTE: Cap or plug opening(s) to prevent fluid from spilling.
  6. Remove front drive shaft (both side). Refer to "EXPLODED VIEW ".
    NOTE: Cap or plug opening(s) to prevent fluid from spilling.
  7. Disconnect harness connector from transmission assembly and transfer assembly.
  8. Disengage A/T control rod at A/T shift selector side. Then, temporarily secure it on the transmission assembly, so that it does not sag. Refer to "EXPLODED VIEW ".
  9. Remove rear plate cover from oil pan (upper). Then remove bolts fixing drive plate to torque converter. Refer to "AWD: EXPLODED VIEW ".
  10. Remove bolts fixing the transmission assembly to lower rear side of oil pan (upper). Refer to "AWD: EXPLODED VIEW ".
  11. Remove front stabilizer connecting rod from transverse link. Refer to "EXPLODED VIEW ".
  12. Remove lower ends of left and right steering knuckle from transverse link. Refer to "EXPLODED VIEW ".
  13. Separate steering outer sockets from steering knuckle. Refer to "AWD: EXPLODED VIEW ".
  14. Remove transverse links mounting bolts at suspension member side. Refer to "EXPLODED VIEW ".

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 bolts.
  3. Remove front suspension member mounting bolts and nuts. Refer to "EXPLODED VIEW ".
  4. Carefully lower jack, or raise lift to remove the engine, transmission assembly, transfer, front final drive assembly and front suspension member. When performing work, observe the following caution:
    CAUTION:
    • Confirm there is no interference with the vehicle.
    • Check that all connection points have been disconnected.
    • Keep in mind the center of the vehicle gravity changes. If necessary, use jack(s) to support the vehicle at rear jacking point(s) to prevent it from falling it off the lift.

Separation Work

  1. Install engine slingers into front of cylinder head (bank 1) and rear of cylinder head (bank 2).

    Slinger bolts: 

    Torque : 28.0 N.m (2.9 kg-m, 21 ft-lb) 

    • To protect rocker cover against damage caused by tilting of engine slinger, insert spacer between cylinder head and engine rear lower slinger (3), in direction shown in the figure.
