Daewoo Nubira Head Torque specs

My daughter bought a 1999 daewoo nubira 2.0 on ebay. After a few weeks of driving it the car started to act up. I noticed some brown milky stuff in the overflow reservoir and thought it was rust, so I did a radiator flush. Come to find out this milky stuff was block sealer. Now that I washed out all the sealer I ended up with water in my exhaust and oil. Major problem.
Head gasket?? Cracked head??
After I removed the head it had bad pits between the water ports and it had to be welded and re surfaced. Only $194.00.
Bought new gaskets, head bolts and timing belt on ebay for great price. Today I started putting it back together.
The machine shop gave me a torque spec sheet. It said cylinder head torque 18ft/lbs +90 degree, +90 degree, +90 degree. Here is my Question, What does 90 degree three times mean???
I saw on line some where the torque should be 65 ft/lbs.
I need some help.
Thank you!!

The head bolts are "Torque to Yield" or TTY bolts. Like a standard head bolt, a TTY bolt will stretch and spring back up to its yield point. But once the yield point is passed, the bolt becomes permanently stretched and does not return to its original length. Because of this, TTY bolts should not be reused. The torque procedure for tightening a TTY head bolt involves tightening it until a certain torque reading is reached. Then the bolt is given an additional turn to a specified angle (say an additional 45 to 90 degrees) to load the bolt beyond its yield point for maximum clamping pressure. There is a tool called a "Torque-To-Angle Indicator" gauge and is used with a torque wrench to achieve proper bolt loading.

I am having the same problem with My Daewoo Nubria as in the message posted #123 . It wants to pull to the left when you give it gas. When you let off the gas it will pull back to the right. I need to know where I can purchase the lower bushings for the torque steering. I will have to do the repair. I will take the car to get a 4 wheel alignment once I replace the bushings. Just help me find a place to buy the lower bushings for the torque steering..

I replaced the hoses yesterday that go to Transmission from Radiator and I have noticed the car now has a slugish start from stop. The car idles lower. Seems like power loss. Any ideas why?

What all should be changed with the timing belt? The water pump and anything else?

Overheating Issue

I seem to have a coolent leak, which is causing overheating unless I keep adding coolent. I bought a bottle of that radiator sealent, but can not find the radiator cap to put it in. Is this because its a seeled system? What can I do to solve this problem without spending tons of cash at the mechanics? Thanks

If you use that radiator sealent in it, you definitely will be spending tons of cash either at the mechanic or to replace the car.
No two ways around it, your cooling system needs a pressure check with the correct equipment. Most independent shops are very reasonable to diagnose the problem.
Aside from you actually carefully inspecting your hoses and finding the leak, you are out of luck without the proper tools.

There should be a plastic resivor with a tube running to the radiator to add coolant. I think you water pump is going out. It's internal so you may need mechanics and also change the timing belt.

I have just spent a lovely day driving with my family when I noticed the temperature gauge up high and a little yellow light on in my dash. On opening the hood I saw a tiny amount of water coming out from where the radiator hose enters the main body of the engine. I know the hundreds of thoughts that it could have been, but I called my local RAC ma. My RAC Roadside Assistant said it could have been a worn (pressure) 'O'ring or a carroded coupling. I'll find out tomorrow & post what it was. Sometimes things that seem major are only little things!!!
