I need rthe torque settings for cylinder head bolts as well as the sequence to tighten the bolt

Yes, I can help you with the cylinder head torque wrench setting for your Hyundai Atos 1.0cc. Here are the torque specifications:

First pass: Tighten all bolts to 18 lb-ft (25 Nm)
Second pass: Tighten all bolts to 45 lb-ft (61 Nm)
Third pass: Tighten all bolts to a final torque of 65 lb-ft (88 Nm)
It's important to tighten the bolts in the correct sequence. The sequence is as follows:

10 6 2 3 7
9 5 1 4 8

Note: The numbers above refer to the cylinder head bolts in the correct sequence. Always use a calibrated torque wrench to ensure that the bolts are tightened to the correct specification.

I hope this helps you with your cylinder head installation. If you have any further questions or concerns, feel free to ask.

BOLT INSTALLATION


Apply engine oil to the thread of the bolts and to the washers.
Tighten the bolts to the specified torque, using the tightening sequence shown.
Tightening torque: 54 ft-lb +/- 2 ft-lb
Loosen all bolts fully in the reverse order of tightening.
Re-tighten the loosened bolts to the specified torque in the tightening sequence shown.
Tightening torque: 15 ft-lb +/- 1 ft-lb
This step is to make it easier to ensure you are making 90 degree turns. Make a paint mark across each bolt head and cylinder head.
Tighten the cylinder head bolts 90 degrees in the specified order.
Tighten the bolts another 90 degrees in the specified order and check that the paint marks on the cylinder head bolts are aligned with the paint marks on the cylinder head.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day

To install:

Fig. Cylinder head bolt torque sequence-3.8L engine

1. Install the new cylinder head gasket with the arrow pointing to the front of the engine.
2. Install the cylinder head.
3. Install NEW cylinder head bolts. Torque the bolts in sequence, as follows:
   1. Step 1: 37 ft. lbs. (50 Nm).
   2. Step 2: Plus 120 degree turn.

To install:

Fig. Tighten the cylinder head bolts using the following sequence-31L and 3.4L engines

1. Install the cylinder head with a new gasket.
2. Apply thread sealer to the head bolts.
3. Tighten the cylinder head bolts to 37 ft. lbs. (50 Nm) plus an additional 90 degree turn.

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.

Please don't forget to rate....thanks:

1. Tighten the engine cylinder head bolts in sequence according to the following procedure
   
   CAUTION During the final tightening sequence, bolt No.11 will be tightened to a lower torque than the rest of the bolts. DO NOT over tighten bolt No.11.
   
   
2. Tighten all bolts in sequence (1 through 14) to 22 ft. lbs. (30 Nm).
   
3. Tighten all bolts in sequence (1 through 14) to 45 ft. lbs. (61 Nm).
   
4. Check all bolts to verify they are set to 45 ft. lbs. (61 Nm).
   
5. Tighten bolts in sequence:
   
6. Bolts 1 through 10 to 110 ft. lbs. (149 Nm).
   
7. Bolt 11 to 100 ft. lbs. (135 Nm).
   
8. Bolts 12 through 14 to 110 ft. lbs. (149 Nm).
   
9. Check all bolts in sequence to verify the correct torque.
   

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
