WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. Before installing the bearing cap bolt, check the bolt screw head is not damaged. If the screw head extremely gets damaged, replace it with a new bolt. The standard length of the new bolt measured from under the head is as follows:

    Standard value: 91.2 - 92.2 mm (3.59 - 3.63 inches)

  2. Attach the bearing cap on the cylinder block as shown in the illustration.
  3. Tighten the bearing cap bolts to specified torque in the sequence shown in the illustration.

    Tightening torque: 24 ± 2 N.m (18 ± 1 ft-lb) 

  4. Make a paint mark on the head of each bolt.

    CAUTION:
    • When the tightening angle is smaller than the specified tightening angle, the appropriate tightening capacity cannot be secured.
    • When the tightening angle is larger than the specified tightening angle, remove the bolt to start from the beginning again according to the procedure.
  5. Make a paint mark on the bearing cap 90 degrees from the paint mark made on the bolt, in the direction of tightening the bolt.
  6. Turn each bolt 90 degrees in the tightening sequence specified in step  2, and make sure that the paint marks on the bolt and cap are aligned.
  7. Check that the crankshaft rotates smoothly.
  8. Check the end play. If it exceeds the limit value, replace the thrust bearing.

    Standard value: 0.05 - 0.25 mm (0.002 - 0.009 inch) 

    Limit: 0.3 mm (0.01 inch)
