   1. Clean the O-ring groove of the cam timing oil control solenoid assembly.
      NOTE:

      Make sure the O-ring groove is free of foreign matter.

   2. Install a new cam timing oil control solenoid O-ring to the cam timing oil control solenoid assembly.
      NOTE:

      Do not damage the cam timing oil control solenoid O-ring when installing it.

   1. Apply a light coat of engine oil to the cam timing oil control solenoid O-ring.
      NOTE:

      If reusing the cam timing oil control solenoid assembly, be sure to inspect the cam timing oil control solenoid O-ring.

   2. Using an 8 mm socket wrench, install the cam timing oil control solenoid assembly to the No. 2 timing chain cover assembly with 2 new bolts.

      Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf) 

      NOTE:

      • If the cam timing oil control solenoid assembly has been struck or dropped, replace it.
      • Make sure that the cam timing oil control solenoid O-ring is not cracked or moved out of place when installing the cam timing oil control solenoid assembly.
   3. Connect the cam timing oil control solenoid assembly connector.

   1. Apply a light coat of engine oil to the cam timing oil control solenoid O-ring.
      NOTE:

      If reusing the cam timing oil control solenoid assembly, be sure to inspect the cam timing oil control solenoid O-ring.

   2. Using an 8 mm socket wrench and 8 x 10 mm offset long wrench, temporarily install the cam timing oil control solenoid assembly to the No. 2 timing chain cover assembly with 2 new bolts.
      NOTE:

      • If the cam timing oil control solenoid assembly has been struck or dropped, replace it.
      • Make sure that the cam timing oil control solenoid O-ring is not cracked or moved out of place when installing the cam timing oil control solenoid assembly.
   3. Using an 8 mm socket wrench, tighten the bolt (A).

      Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf) 

   4. Using an 8 x 10 mm offset long wrench and 10 mm hexagon socket wrench, tighten the bolt (B).

      Specified tightening torque 

      Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf) 

      HINT: 

      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

        Refer to PRECAUTION [03/2023 - ]

      • When using an 8 x 10 mm offset long wrench (fulcrum length of 164.5 mm (6.48 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):

        5.0 N*m (51 kgf*cm, 44 in.*lbf)

   5. Connect the cam timing oil control solenoid assembly connector.

Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf)
