Where is egr valve located on 2006 Cadillac DTS


I'm not familiar with your vehicle (I'm in the UK). However, the EGR valve is usually connect to the air intake.

Look for a 'unit' that is connected to the air intake via a tube.

Here's a link done with a general Google search for '2006 Cadillac DTS egr'. Hopefully you will recognise your own egr valve amongst the images:

Oxygenator causing random missing


ok so throwing parts at it might fix it but more than likely you have an issue with coolant seeping into the intake from the upper intake manifold (its plastic) where the EGR tube connects to the upper manifold. There is a new updated intake for those engines, which has a bigger diameter where the tube connects, (the tube burns thru the plastic).
check which cylinder is misfiring (P0301 indicates cyl. 1 and P0302 cyl. 2 and so on) and the pull the plug where the misfire indicates and see what it looks like. Check coolant levels to verify no coolant is internally leaking in to the engine. If this is the problem you need to have it repaired immediately or risk hydro-locking the engine. If this is the case you will need to pull all the plugs and replace them, but before installing the new plugs, be sure to crank the engine over about 3 times to expel all the liquid from the cylinders.

Starter needs to be replaced. Need instruction procedure for a do it yourselfer.


Hi, I have pasted the procedure from autozone.com below. Because this requires removal of the intake manifold, please be as sure as possible that your starter needs replacement. If you have any doubt, please let me know what your symptoms are and what troubleshooting you have done that led you to believe your starter is bad. Also, if you have any questions about the procedure below, please let me know. Thanks for using FixYa.


Removal & Installation


Disconnect the Negative battery cable


Relieve the fuel system pressure (you can do this by placing a rag over the schrader valve on the fuel rail and pressing in the valve stem--just be careful not to spray fuel on your eyes).


Drain the cooling system.


Remove or disconnect the following:


  • Intake manifold heat shield
  • Sight shield
  • Coil module connectors from the coil modules located on the valve covers
  • Positive Crankcase Ventilation (PCV) hose and valve from the valve cover
  • Fuel regulator vacuum tube
  • Vacuum tubes from the AIR solenoid
  • Fuel inlet and return lines
  • Fuel rail bracket retaining nut at the rear lift bracket
  • 2 pushnuts attaching the engine coolant heater wire and set it aside, if equipped
  • Fuel injector electrical connections
  • Fuel rail and injectors
  • Plenum duct clamp at the rear of the intake manifold, loosen
  • Intake manifold bolts and the manifold
Clean the manifold mating surfaces.


Remove or disconnect the following:
Starter electrical connectors Starter motor

To install:

Install or connect the following:

  • -S- terminal wire. Torque the nut to 35 inch lbs. (4 Nm).
  • Starter electrical connectors. Torque the nut to 89 inch lbs. (10 Nm).
  • Starter motor
  • Mounting bolts. Torque the bolts to 22 ft. lbs. (30 Nm).

    2. Place the front of the intake manifold downward on to the cylinder heads.

  3. Install the intake manifold bolts and torque to 89 inch lbs. (10 Nm) in the sequence illustrated. DO NOT torque the intake manifold bolts when the engine is HOT or at operating temperature.
  4. Make sure the plenum duct is fully attached to the rear of the intake manifold and tighten the plenum duct clamp to 20 inch lbs. (2.25 Nm).
  5. Install or connect the following:

How to install a intake on a big block chevy corvette


That depends on type of gasket being used. Some fel-pro gaskets have sealant built into the gaskets, I have used some sealant to help hold gaskets in place around bolt holes during installation but that's not always necessary...and yes there is a torque sequence for intake manifolds...example given in link.

The balancer should be torqued also...85 - 90 Ft-lbs if I remember correctly. The balancer should be all the way back when completely torgued, if not you may need to check for clearance problems.

Hi sapperstein,

What you're looking for should be on the upper end of the tappet cover, and connected to the intake manifold, probably by way of a flexible tube....PVC refers to 'positive crank ventilation'..... It a way of re-burning the gases, created in the crank case....
