Parts Requiring Angular Tightening

  1. Use an angle wrench for the final tightening of the following engine parts. Cylinder head bolts Lower cylinder block bolts Connecting rod cap bolts Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
  2. Do not use a torque value for final tightening.
  3. The torque value for these parts are for a preliminary step.
  4. Ensure thread and seat surfaces are clean and coated with engine oil.
