INSTALL CYLINDER HEAD SUB-ASSEMBLY

Tech Tips

The cylinder head bolts are tightened in 4 progressive steps.

Place the cylinder head sub-assembly on the cylinder block sub-assembly.
Note
- Ensure that no oil is on the contact surface of the cylinder head sub-assembly.
- Place the cylinder head sub-assembly on the cylinder block sub-assembly gently in order not to damage the cylinder head gasket with the bottom of the cylinder head sub-assembly.
Install the 10 plate washers to the 10 cylinder head bolts.
Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.
Step 1:
1. Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 10 cylinder head bolts in several steps in the order shown in the illustration.
  
  Torque:
  
  36 N*m { 367 kgf*cm, 27 ft.*lbf }
  
  Note
  
  Do not drop the plate washers for the cylinder head bolts into the cylinder head sub-assembly.
Step 2:
1. Check that the cylinder head bolts are tightened to the specified torque.
  
  Torque:
  
  36 N*m { 367 kgf*cm, 27 ft.*lbf }
Step 3:
1. *a Paint Mark
  
  Front of Engine
  
  Mark each cylinder head bolt head with paint as shown in the illustration.
2. Tighten the cylinder head bolts 90° in the order shown in step 1.
Step 4:
1. Tighten the cylinder head bolts another 90° in the order shown in step 1.
2. Check that the paint marks are now facing rearward.
  Note
  - Do not install the timing chain cover assembly for at least 2 hours after installation.
  - Do not start the engine for at least 2 hours after installation.
