Harness clip
Remove the harness clip to access the engine mount support bolts.Inspection Procedure
Check the clearance between the support and the engine flywheel housing by using the thickness gauge.Note: The thickness gauge should not enter into the gap between the support and housing.
Inspect the torque of the eight 143-0116 Bolts . Apply the static inspection torque in the direction of tightening.Note: The static inspection torque for the bolts is 80 N m (59 lb ft). The bolts should not move when the static inspection torque is applied.
If the thickness gauge entered the gap, or the bolts moved when the static inspection torque was applied, tighten the bolts to a torque of 100 20 N m (74 15 lb ft).
