    Default How to tell if your G8 is a 2009.5

    Took a qustion today by phone from a real cool guy in New York. 84yo and still loves his Pontiacs. Thought I would share for anyone else interested.
    2009.5 G8 ?

    --------------------------------------------------------------------------------



    Control Systems:
    ECM (GT/GXP Share Same New OS)
    TCM (GT/GXP Share Same New OS)
    BCM (New 09.5 Calibration with many subsystem changes)
    IPC (Totally New Hardware/Calibration NOT Compatible with 08/09)
    Radio (New Part # for Face and Unit)
    VCIM (New Part to add Bluetooth)
    Interior:
    Cup Holders Added To Rear Seat Bottom
    Engine:
    New Valley Plate/Oil Module for L76
    New Timing Chain Tensioner
    New Water Pump
    New Radiator Hoses
    New ECM Mounting Bracket
    New Camshaft for L76 (Unverified physically but very likely)
    New Diameter for foul air passage
    Exhaust:
    Additional Two Pup Cats Added to Mid Pipe Section for GT/GXP
    Body:
    Rear fascia retooled for GXP Style Valence (may have happened earlier in 09 not sure)

    Lots of little things under the skin, especially electronics, otherwise you can't "tell" a difference, bluetooth and rear cupholders aside.
    Also if your car last 6 digits of your vin starts with the #3.
    All GXP's are 2009.5.

    Thanks for the information. I believe my G8 is one of the late cars. I will check my VIN.
