- Lubricate bolt threads with clean engine oil and install bolts.
- Tighten bolts in sequence, using the following steps and torque values:
- Step 1: Bolts 1-8 to 48 N.m (35 ft. lbs)
- Step 2: Bolts 1-8 to 75 N.m (55 ft. lbs)
- Step 3: Bolts 1-8 to 75 N.m (55 ft. lbs)
- Step 4: Bolts 1-8 to +90° Turn Do not use a torque wrench for this step.
- Step 5: Bolts 9-11 to 28 N.m (250 INCH lbs)
