What are the torque specifications and tightening sequence for cam journal and cylinder head for 2001 daewoo nubira 2.0 :(

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.

Cylinder head bolts are usually tightened to around 65 ft-lbs, depending on what the car is.

There's more than 4 cylinder head bolts... There's usually 10 bolts.
There's also a sequence for tightening the bolts:

cylinder head tightening order Google Search

When tightening cylinder head bolts do it in 'stages' and follow the sequence .. ie.. tighten the bolts finger tight first, then torque them up to about 25 ft-lbs. Wait 2 minutes.

Then tighten them to about 45 ft-lbs in sequence. Wait 2 minutes.

Do it again up to about 55 ft-lbs. Wait 2 minutes.

Tighten them up to 65 ft-lbs or whatever is recommended for your car.

Tightening in order/sequence pulls the cylinder head evenly onto the block. Waiting 2 minutes between stages allows a 'stretched' bolt to 'settle'.

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.

1. Tighten cylinder head bolts to 25 N.m (18 ft. lbs.). Tighten bolts an additional 70 degrees plus 70 degrees plus 30 degrees using angular torque gauge .

Cylinder heat bolt torque:
Torque sequence --------- front | 7 3 1 5 | | 8 4 2 6 | --------- Step 1: Torque all bolts in sequence to 14 Ft/Lbs Step 2: Torque all bolts in sequence to 29 Ft/Lbs Step 3: Torque all bolts in sequence to 36 Ft/Lbs Step 4: in the sequence, loosen the cylinder head bolts three turns. Step 5: Tighten short bolt to 15 - 32 Ft/Lbs Step 6: Tighten long bolt to 30 - 36 Ft/Lbs Step 7: Tighten all bolt to 175- 185 degree note: Do not loosen all of the cylinder head bolts at one time. Each cylinder head bolt must be loosened and the final tightening prior on the next bolt in the sequence.
Main bearing torque:
Torque sequence: Step 1: torque bolts to 91 Ft/Lbs with the exception of the rear main bearing cap Step 2: torque rear main bearing cap bolts to 88 Ft/Lbs Step 3: torque brace bolts to 40 Ft/Lbs
Connecting rod torque:
Torque sequence Step 1: Torque to 29 Ft/Lbs Step 2: Turn an additional 90 degrees

1. CAUTION: Always install new cylinder head bolts. NOTE: Lubricate the cylinder head bolts with Super Premium 5W 30 SAE X0-5W 30-QSP or equivalent meeting Ford specification WSS-M2C153-G prior to installation. Install the cylinder head assembly and tighten the cylinder head bolts in the following sequence.

1. Tighten all bolts in a single sequence to 50 Nm
2. Back the bolts off 1/2 turn.
3. Tighten the bolts in sequence shown to 50 Nm .
4. Rotate all the bolts in a single sequence an additional 180 degrees in two steps of 90 degrees each.

Spec for rod 38Nm

Tighten the cylinder head bolts 1 - 8 in the sequence shown in Cylinder Head Bolts Location and Tightening Sequence Using the 4 step torque turn method, tighten according to the following values:
Step 1: Bolts 1 - 8 to 61 N·m (45 ft. lbs.)
Step 2: Bolts 1 - 8 to 88 N·m (65 ft. lbs.)
Step 3: Bolts 1 - 8 (again) to 88 N·m (65 ft. lbs.)
Step 4: Bolts 1 - 8 turn an additional 1/4 Turn. (Do not use a torque wrench for this step.)
NOTE: Bolt torque after 1/4 turn should be over 122 N·m (90 ft. lbs.) If not, replace the bolt.

Tighten head bolt number 9 Cylinder Head Bolts Location and Tightening Sequence to 33 N·m (25 ft. lbs.) after head bolts 1 - 8 have been tighten to specifications.
