Need to know how much torque to tighten head bolts and connectingrods

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.

The torque specification for the head bolts on a 1997 Toyota Corolla is usually between 26 and 30 foot-pounds. It's important to note that the torque specification can vary depending on the specific engine and head bolt type, so it's always best to consult a service manual or other reliable source for the most accurate and up-to-date information.

It's also important to follow the proper tightening sequence when installing the head gasket. The tightening sequence is usually specified in the service manual and is designed to ensure that the head bolts are tightened evenly and to the proper torque specification.

I recommend using a torque wrench to ensure that the bolts are tightened to the proper torque specification. It's also important to use a torque angle gauge to ensure that the bolts are tightened to the proper angle.

I hope this helps! Let me know if you have any other questions.

The site that has that information is called alldata and it is not free.

Get a HAYNES or CHILTON manual. Is has all tghe steps and tightening torque values. The usual tightening sequence is to start at the center bolt, follow with the center one opposite to it, then follow an spiral going out until you reach the last bolt. As usual, you need to do it in three steps, with a decent torque wrench.

Cylinder head bolt torque spec are

First Tightening Pass --- 22 Ft. Lbs or 30 N.m
Second Tightening Pass --- 155 Degrees
