INSTALL CYLINDER HEAD LH

Tech Tips

Perform "Inspection After Repairs" after replacing the cylinder head LH.

Place the cylinder head LH on the No. 2 cylinder head gasket.
Note
- Make sure that no oil is on the mounting surface of the cylinder head LH.
- Do not damage the cylinder head LH and No. 2 cylinder head gasket.
Apply a light coat of engine oil to the threads and under the heads of the cylinder head set bolts.
Install the 8 cylinder head set bolts and 8 plate washers.
Note
- Install the cylinder head set bolts to their original positions.
- Do not drop the plate washer for the cylinder head set bolt into the cylinder head LH.
- The cylinder head set bolts are tightened in 2 progressive steps.
- If any cylinder head set bolt is broken or deformed, replace it.
Step 1:
1. Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 8 cylinder head set bolts with plate washers in several steps in the sequence shown in the illustration.
  
  Torque:
  
  36 N*m { 367 kgf*cm, 27 ft.*lbf }
  
  If any one of the cylinder head set bolts does not meet the torque specification, replace the cylinder head set bolt.
Step 2:
1. Mark the engine front side of each cylinder head set bolt head with paint.
2. Tighten the cylinder head set bolts 180° in the sequence shown in step 1.
Check that the painted marks are now facing rearward.
Apply a light coat of engine oil to the threads of the bolts.
Install the 2 bolts. Using several steps, tighten the bolts uniformly in the sequence shown in the illustration.

Torque:

30 N*m { 306 kgf*cm, 22 ft.*lbf }
