Head Bolt torque and sequence needed?

Here are the head bolt tightening instructions you have requested below.

Important: Use new cylinder head bolts. The required tightening method stretches the bolts; therefore, the cylinder head bolts are not reusable.

Install new cylinder head bolts. Tighten cylinder head bolts in the proper tightening sequence and in stages.
Torque:
Cylinder Head Bolt: 25 N.M (18 ft. Lbs.) + 90 degrees + 90 degrees + 90 degrees + 15 degrees

Check out the sequence in the images below.

Hi,

I attached the directions below. Indicated is the front cylinder head. The rear follows the same procedure.

Note that you need to be using new head bolts. Torquing the head requires a multi-step process. In reality, you should have a torque angle gauge to do it properly because you tighten them (in sequence) to a specified torque. After that, you retorque the bolts 4 more times in increments of 90 degrees. The fifth time, they are torqued an additional 15 degrees.

Take a look at the pics below and let me know if you have questions.

Take care,

joe
