Needing engine bolt torque specifications for a 2006 Ford Five Hundred with 3.0 liter engine. This will need to include rod and mains torque and torque rotation.


stage 1 tighten to 30 ft pounds
stage 2 tighten 90 degrees
stage 3 loosen one full turn
stage 4 tighten to 30 ft pounds
stage 5 tighten 90 degrees
stage 6 tighten 90 degrees
this is per mitchell on demand courtesy of ford specs on the lft and right head.
for some reason there are no torque specs on mitchell for connecting rods and mains.

  • NOTE: Use new connecting rod bearing cap bolts.

  • Position the corresponding bearing shells, clean and free of oil, into the connecting rod and the connecting rod bearing cap.
  • Coat the inner side of the bearing shells with engine oil.
  1. NOTE: The crankshaft must rotate freely, if necessary check and adjust the bearing clearances.
    Tighten the main bearing and connecting rod bearing bolts.
    1. Tighten the main bearing bolts in two stages.
      • Stage 1: 25 Nm.
      • Stage 2: 60 degrees.
    1. Tighten the connecting rod bearing bolts in two stages.
      • Stage 1: 35 Nm.
