    i dont think yall are talking about the same thing. the coolant fill for the supercharger is located on the PASSANGER SIDE of the car and is the clear tube with a cap on it and two hoses attached one going into it and one leaving it. the coolant fill for supercharger IS NOT LOCATED ON THE SUPERCHARGER. take a pic of the part you are questioning, id be easier since there are many things under the hood.

    I think he is talking about the black square panel on top of the supercharger.

    ^^^^ if its got to bolts holding it down it's a coolant fill for if you empty the system and need to refill. Other wise you fill in the plastic fill tube on the passenger side by the fire wall.

    Caution!
    The procedure below must be followed. Improper coolant level could result in poor system performance.

    Important
    The charge air cooling system is filled through the charge air coolant cap and the charge air coolant fill neck.

    Loosen the charge air coolant radiator vent plug.
    Place a shop towel around the charge air coolant radiator vent plug to absorb any leakage.

    • Pour coolant in very small amounts to avoid coolant spillage from the charge air coolant port or from the funnel.
    Using a small funnel, slowly fill the charge air cooling system through the charge air coolant cap port with a 50/50 coolant mixture until coolant is present at the charge air coolant radiator vent plug.
    Hand tighten the charge air coolant radiator vent plug.


    Using a small funnel, continue to slowly fill the charge air cooling system through the charge air coolant cap port until coolant is level with the charge air coolant cap port.
    Important
    Do not cycle the charge air cooling system without the charge air cooling cap in place or coolant loss will occur.

    Install the charge air coolant cap.
    Install the charge air coolant cap bolts
    Tighten
    Tighten the plug to 10 Nm (89 lb in).


    Slowly fill the charge air cooling system through the charge air coolant fill neck until coolant reaches the COLD FILL mark.
    Important
    Cycle the charge air coolant system by using the Tech 2 or by starting the engine.

    Cycle the charge air cooling pump ON and continue to slowly fill through the charge air coolant fill neck until the level stabilizes at the COLD FILL mark.

    Slowly loosen the charge air coolant radiator vent plug until coolant is present.
    Remove the shop towel from around the vent port.
    Tighten the charge air coolant radiator vent plug.
    Tighten
    Tighten the plug to 10 Nm (89 lb in).

    Continue to slowly fill through the charge air coolant fill neck until the level has stabilized at the COLD FILL mark.
    Cycle the charge air coolant pump OFF.

    Remove the charge air coolant cap bolts.
    Remove the charge air coolant cap.
    Ensure that coolant is almost level with the coolant cap fill port.
    Top off with the 50/50 coolant mixture through the charge air coolant cap port, if necessary.

    Install the charge air coolant cap.
    Install the charge air coolant cap bolts.
    Tighten
    Tighten the plug to 10 Nm (89 lb in).

    Important
    Do not cycle the charge air cooling system without the charge air cooling cap in place or loss of coolant will occur.

    Cycle the charge air coolant pump ON for 3 minutes.
    Cycle the charge air coolant pump OFF.
    Fill through the charge air coolant fill neck until the level stabilizes at the COLD FILL mark.
    Repeat steps 19-21 until level is stabilized at the COLD FILL mark with the charge air coolant pump in the OFF position.
    Inspect the concentration of the engine coolant, using the J 26568 .
    Install the charge air cooling system pressure cap.
    Inspect the charge air cooling system for leaks.



    That sounds like a lot of work just to add. I would use the inline fill for add, but the full procedure for starting from empty.

    Yep sounds right it takes along time to fill when empty and get all the air out.
