What is the toqrque spechs and order for a Northstar 4.6 engin for both head and main & rod barngs. Does the main barnings have a order


If you have to pull a cylinder head on a 1993-1999 4.0L or 4.6L Northstar V8 to replace a gasket or do a valve job, do not reuse the old 11mm head bolts. Also, GM has revised the head bolt torque values and tightening procedure as follows:
  1. In sequence, torque all bolts to 30 ft.-lbs.
  2. In sequence, rotate all bolts an additional 70 degrees.
  3. In sequence, rotate all bolts an additional 60 degrees.
  4. In sequence, rotate all bolts another 60 degrees.
  5. Torque the front three M6 head bolts to 106 in.-lbs.

2000 cadillac northstar running hot


I just had to rebuild my wife's Northstar. You have a bad head gasket. Her's was doing the same thing, and not showing traditional signs of head gasket problem. (IE: white smoke) It was just overheating with normal use.

Northstar loses a qt of antifreeze every week. No drips leaks seen anywhere. Oil level is ok and water free.


Most likely the Northstar engine has a failed head gasket.These are notorious for this.Take to a reptuable shop and have vehicle block tested.If they dont know what you are talking about,go to another till you find one that does.

Idles high, running temperature is 225 degrees and have to push on accelerator to start


hi,

are you familiar with the northstar engine?
first generation northstars are notorious for this kind of thing..
the engine is prone for metal fatigue/ warping of the heads, and stripped out head bolts, do you have documentation and service history for it?
these engines need a good mechanic to inspect and replace head bolts which strip out and need fixing. I will post a link at the bottom
once the engine is repaired correctly it should last a good long time
have it fixed correctly. I think someone has turned up the idle knob in an attempt to get the coolant flowing quicker to keep it cool.
its worth repairing if you have the money..
