Tighten the cylinder head bolts to their final torque specification in two steps. Use a crisscross sequence starting with the bolts at the middle of the head and working toward the outer bolts.

1. Step 1: Tighten each bolt to 22 ft. lbs. (30 Nm).
   
2. Step 2: Tighten each bolt to 61 ft. lbs. (85 Nm).

Hope helps.

VOLKSWAGONS YOU NEED CYLINDER HEAD REMOVE SEQUENCE AND CYLINDER HEAD TORQUE SEQUENCE.YOU NEED A REPAIR MANUAL FOR TORQUE SEQUENCE OR YOU WILL HAVE HEAD GASKET LEAKS. TORQUE HEAD BOLTS TO * STEP 1 * TORQUE BOLTS 30 FT LBS * STEP TWO * TIGHTEN BOLTS 44 FT LBS STEP 3 TIGHTEN BOLTS PLUS 90 DEGREES.* STEP FOUR* TIGHTEN BOLTS PLUS 90 DEGREES AGAIN.

Check this procedure...

1. Tighten the first design cylinder head bolts as follows:
   1. M11 bolts 1st pass: in sequence to 22 ft. lbs. (30 Nm).
   2. M11 bolts 2nd pass: in sequence + 90 degrees.
   3. M11 bolts (1,2,3,4,5,6,7,8): + 90 degrees.
   4. M11 bolts (9 and 10): + 50 degrees.
   5. M8 cylinder head bolts (11,12,13,14,15) to 22 ft. lbs. (30 Nm). Begin with the center bolt (11) and alternating side-to-side, work outward tightening all of the bolts.
      
2. Tighten the second design cylinder head bolts as follows:
   1. M11 bolts (1-10) 1st pass: in sequence to 22 ft. lbs. (30 Nm).
   2. M11 bolts (1-10) 2nd pass: in sequence + 90 degrees.
   3. M11 bolts (1-10): + 70 degrees.
   4. M8 cylinder head bolts (11,12,13,14,15) to 22 ft. lbs. (30 Nm). Begin with the center bolt (11) and alternating side-to-side, work outward tightening all of the bolts.

Install the cylinder head bolts in sequence to 22 ft. lbs. (30 Nm). The bolts must be tightened once, then be tightened again in sequence in the following order:

1. Step 1: Short length bolt: (3, 4, 7, 8, 11, 12, 15, 16), plus 55 degrees.
2. Step 2: Medium length bolt: (14, 17), plus 65 degrees.
3. Step 3: Long length bolts: (1, 2, 5, 6, 9, 10, 13), plus 75 degrees.

① Step 1: 44 ft. lbs. Step 2: plus 95 degrees

Driver's side head--



Install the NEW cylinder head bolts. Tighten the bolts as follows:

• Tighten the bolts in sequence to 44 ft. lbs. (60 Nm).
  
• Turn the bolts in sequence an additional 95 degrees.
  

Tighten in sequence to 29ft.lbs then tighten in sequence to 58ft lbs. then loosen all bolts. Then tighten in sequence to 33ft lbs. then tighten each bolt in sequence 90 degrees then tighten each bolt again 90 degrees

There should be 10 headbolts. This vehicle uses torque to yield headbolts and should be replaced with the new gasket. Bolts 1-8 get torqued to 40 ft lbs initially, bolts 9 and 10 get torqued to 30 ft lbs initially, Then all bolts get turned an additional 90 degrees. I would strongly suggest borrowing a torque angle gauge for doing this or you might be doing the same repair next week.

New Headbolts are recommended

Long bolts are torqued to 46'lbs + 90 degrees.

Short bolts are torqued 43'lbs + 90 degrees.

Start in the center, and work to the edges, torquing the bolts in two stages.

Rockers are torqued to 22'lbs.
