2006 S-type supercharger removal

The title says it all! I removed the supercharger on a 2006 S-type R to fix a coolant hose. Here are the pics and how I did it:
  • Here we go!
  • First off I removed the top engine cover, the wipers, the cowling, and the intake boot. That should be pretty straight forward, notice that I marked the position of the wipers with blue tape.


  • It might be a good idea to blow the engine so no debris falls inside since we are taking the intake system apart. There is a clamp that holds the main intake tube in place, loosen it and remove it carefully so as not to rip the rubber apart.

  • Remove the expansion tank and the front cover.

  • Undo the two hoses on the pic, and move it to the right out of the way.
  • Remove the thermostat housing which is held in place by four bolts and four hoses, two on each side, one below and a big one behind it. You also need to unplug the temperature sensor.


  • Remove the three part hose in the pic, and move it our of the way. Then loosen the supercharger belt with a half inch drive ratchet. Just remove the belt from the supercharger, you don't need to take it completely out. Then push it aside.

  • Now it's time to remove the top cover of the supercharger, just 4 bolts and a clamp hold it in place. Your main concern is the hose, you don't want to mess it up unless you have a new one. You might notice that sometimes my pics repeat, usually I take two to make sure they are OK, but I put them both because you can never have too many pics.

  • Removing the throttle body wasn't as hard as I thought, just remove the four bolts, and the connector. Removing the boot (carefully) helps.
  • Now comes the real fun!!! The EGR valve needs to come out, makes everything else much easier. Your main concern here (in this whole procedure this is what you wanna do right!) is DO NOT ROUND OFF THE EGR BOLTS. You want to make sure that when you are taking these out your socket is straight, and spraying it with Rust-off is a good idea.
  • To go at these (after trying and failing miserably I admit it) I realized it becomes much easier if you remove the A/C Cabin Filter and the housing as in the pic.
  • The you have to remove the heater hoses, there is two 10 mm bolts that hold the heater hoses brackets, you want to take those off to allow them to move out of the way (they won't be out off the way they will still annoy you. Just position them where they bother you the least)

  • To take out the EGR valve (shown below), remove the two 13 mm nuts at the bottom of the exhaust pipe. Then there is two 8 mm bolts that hold the valve to the supercharger. I loosened the two nuts with a deep 13 mm socket, a 3/8 swivel extension and a ratchet from the top. The two 8 mm I loosened with an 8 mm socket, a 3/8 to 1/4 inch adapter, and a long non-swivel extension with a 3/8 drive ratchet. MAKE SURE IS STRAIGHT you don't want to round those bolts... One of the hoses as you can see I disconnected at the opposite end. The other hose I took off the EGR, but to get to that one I "fished" the EGR out so it was easy to get my tool to it.
  • You also need to look and remove anything that needs to be removed to the best of your common sense (I couldn't be stopping to take a pic to every single thing I did) but it's not too bad. Of the top of my head I remember moving the harness out of the way, the vacuum tube, a couple of vacuum hoses in the back.
  • So how do you finally take the supercharger out? There is five 10 mm bolts holding the supercharger in place. Look at the next pic of the supercharger already out so you see where they are at. There is two at the back that go to the sides, two super easy at the front, but there is one (one S.O.B. I might add) that is right below it (again look at the pic of the supercharger pic). And there are the pain in the ass hoses!



  • Check back for when I'll post how I put it back together!

    1. Great article. Would have been lost without it. One thing I did different. By removing the plenum (4 bolts on the rear of the sc) it makes the 5th bolt on sc super easy. Thanks for making this available to all who are in a bind.

  11. Excellent report. I need to change my EGR valve on a 2006 STR. Is yours a LHD? I ask because my EGR connects to bank 2 (RHS standing in front of the car looking towards it). Yours seems to have a short exhaust connector pipe.

  12. Re above comment. Of course it is LHD. Just realised where the brake master cylinder and servo are located!

  13. My bad mistake. EGR valve connects to Bank 1 so that is not my problem after all.
    Having inspected the spark plugs on Bank 2 it is suggested that there is a leaking inlet manifold gasket so will need to do all the above to change the inlet manifold gasket.
