Component Tightening Specifications and Sequences

Cylinder Head Bolt





HINT: The cylinder head bolts are tightened in 2 progressive steps.

Apply a light coat of engine oil to the bolt threads and the area beneath the bolt heads that come in contact with the washers.
Install the bolts and plate washers to the cylinder head.

NOTICE: Do not drop the washers into the cylinder head.





Using several steps, uniformly install and tighten the 10 cylinder head set bolts and plate washers with a 10 mm bi-hexagon wrench in the order shown in the illustration.
Torque 70 Nm (714 kgf-cm, 52 ft. lbs.)





Mark the front side of the cylinder head bolt with paint.
Retighten the cylinder head bolts 90° in the sequence shown in the illustration.
Check that the paint mark is now at a 90° angle to the front.





Cylinder Head Set Bolt
Using vernier calipers, measure the length of the head bolts from the seat to the end.
Standard bolt length 141.3 to 142.7 mm (5.563 to 5.618 inch)
Maximum bolt length 144.2 mm (5.677 inch)
If the bolt length is greater than the maximum, replace the cylinder head set bolt.
