  3. Install the BSM mounting bolts.
    1. Tighten the bolts with seating torque 26.4 N.m (3.0 kgf.m, 21.7 lb-ft) and then loosen the bolts.
    2. Using the SST (Torque Angle Adapter, 09221-4A000), tighten the bolts with specified tightening torque and angle.

      Tightening torque 

      Bolts (A) (M9x181.5): 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 88° ~ 92°

      Bolts (B) (M9x100): 22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 43° ~ 47°

      NOTE: Do not reuse the BSM bolts.

  6. Confirm the BSM timing mark.
    1. Turn the crankshaft pulley 4 revolutions and align its groove with the timing mark "T" of the timing chain cover.

      Information 

      If the crankshaft sprocket turns 4 revolutions, the BSM sprocket turns 5 revolutions and the drive shaft turns 8 revolutions.

  7. Install the oil pan.
    1. Using a gasket scraper, remove all the old sealant material from the gasket surfaces.
    2. Before assembling the oil pan, liquid sealant Loctite 5900H, Threebond 1217H or equivalent should be applied on oil pan.

      The part must be assembled within 5 minutes after sealant was applied.

      Bead width:  2.5 mm (0.10 in.)

      NOTE:
      • When applying sealant gasket, sealant must not be protruded into the inside of oil pan.
      • To prevent leakage of oil, apply sealant gasket on the inner threads of the bolt holes.
    3. Install the oil pan (A). Uniformly tighten the bolts in several passes.

      Tightening torque 

      Bolts B (M9): 26.5 ~ 30.4 N.m (2.7 ~ 3.1 kgf.m, 19.5 ~ 22.4 lb-ft)

      Bolts C (M6): 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

      NOTE:
      • After assembly, wait at least 30 minutes before filling the engine with oil.
      • Always use a new drain plug gasket.
  8. Install the A/C compressor bracket (A).

    Tightening torque:  19.6 ~ 23.5 N.m (2.0 ~ 2.4 kgf.m, 14.5 ~ 17.4 lb-ft)
