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.
Tighten the cylinder head bolts. Tighten the cylinder head bolts is sequence to 29 Nm (3.0 kgf-m, 22 ft. lbs.). Use a beam-type torque wrench. When using a preset type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it. Make sure the threads are clean, new heads bolts are best.
The torque settings for the cylinder head on a 2003 Ford Ranger 2.5 turbo diesel WLT engine are as follows:
Main cap bolts: 70 Nm (52 ft-lbs)
Head bolts: 65 Nm (48 ft-lbs)
Rocker arm shaft nuts: 25 Nm (18 ft-lbs)
It is important to note that these torque values are for the cylinder head bolts and main cap bolts only. Other fasteners on the engine, such as the oil pan bolts, may have different torque requirements.
It is also important to use a torque wrench and follow the proper tightening sequence when installing the cylinder head. Consult the service manual for your vehicle or a repair manual for the specific tightening sequence and additional torque specifications.
I hope this information is helpful. If you have any further questions or need additional assistance, don't hesitate to ask.

if this is a aluminum head it will be a torque to yeild. you will need brand new head bolts and a torque to yeild wrench, torque to yeild is not a set value but the stretching point of the bolt, wich a torque to yeild wrench will tell you when the bolt is starting to stretch then you stop and torque is achieved. often the starting torque is approx 30pds then you go back through with the torque to yeild wrench. if it has a cast iron head it will have a set value determined by the manufacture which on this car i do not know off hand. I hope i at least led you in the right direction
Tighten the cylinder head bolts sequentially in three steps. NOTE: Perform each step twice. 1st step torque: 39 Nm (4.0 kgf-m, 29 ft. lbs.) 2nd step torque: 69 Nm (7.0 kgf-m, 51 ft. lbs.) 3rd step torque: 98.1 Nm (10.0 kgf-m, 72.3 ft. lbs.) Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt, and retighten it from the first step.
