  1. Pull the air inlet hose straight (1) upward to disengage it from the grommet located on the top of the radiator fan shroud (2).
  2. Disengage the three retaining clamps (3) that secure the air cleaner housing cover (4) to air cleaner housing (6).
  3. Lift and pull the air cleaner housing cover toward the engine to disengage the cover locating tabs (5) from the air cleaner housing and position the cover out of the way.
  4. Remove the air cleaner element (1) from the inside of the air cleaner housing (2).

PLATE-TORQUE CONVERTER DRIVE

1 - FLEXPLATE
  1. Position the flexplate onto the crankshaft and install the bolts hand tight.
  2. Tighten the flexplate retaining bolts to 60 N.m (45 ft. lbs.) in the sequence shown in illustration.
  3. Install the transmission. Refer to «INSTALLATION»(ref-285318-S04241174302008052100000) .
