I've heard a lot of people say no one will do any major repairs on the Northstar engine because it is so intricate. Plus the bolts could break off or strip the threads. Then you do have problems.

SOURCE: Hello I have a 2000

It can cause it to overheat if it is leaking coolant into the engine or outside of the engine. Replace your thermostat and check your oil for water and your antifreeze for oil. This will confirm if your head gasket or intake manifold gasket is leaking. Check you water pump for leaks and and make sure your coolant reservoir and radiator are full with antifreeze. Another possibility is your catalytic converter is plugged up

SOURCE: we replaced the intake manifold

These have very very specific repair procedures. The intake manifold is leaking coolant into the intake valves. What year and model Cadillac do you have?

SOURCE: I replaced intake manifold gasket

Assuming that the leak was coming from the gasket that you just replaced, it could be due to several factors which include the following:

1) uneven mating condition, between intake and head due to non removal of the old gasket
2) gasket could have shifted out of position while the intake was being put in place
3) over torquing or un-even mating condition could have caused a crack in the composite intake manifold
4) under torqued intake to head attachments.

There are also quick disconnects for the heater hoses which may not be properly retained. These quick disconnects have been known to crack, creating a leak,

I would first determine where the liquid is coming from and then concentrate on that interface to solve the issue.

You can drill it and use an EZ out How to Use Screw Extractor Remove snapped off bolt from engine
Remember to take your time! Go slow and do it right. It's when you try to rush through a job like this and mess it up that you really get into a world of grief. Extractor kits aren't that expensive and always something to have around if you work on cars.

Drilled hole in intake manifold at upper radiator outlet


Did the bolt break off flush with the top of the hole? or if you remove the cover is some bolt sticking up? if there is try and use vice grips to get ahold if the bolts if it is flush then drill the bolt out and re-tap the hole. Way cheaper and likely less work too...

Intake manifold gasket / replace


3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Remove the upper intake manifold using the procedure above.
  4. Remove the EGR outlet pipe from the intake manifold.
  5. Detach the engine coolant temperature sensor wiring harness from the sensor.
  6. Remove the lower intake manifold bolts and carefully lift off the manifold.

To install:

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Upper Intake Manifold (Plenum)
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Tag for identification, then remove the right side spark plug wires.
  4. Disconnect the ignition wires from the fuel rail.
  5. Remove the fuel rail. Please see Section 5.
  6. Remove the cable bracket from the intake manifold.
  7. Remove the throttle body.


NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
  1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces.
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.
