Check the routing of the A/C pipe (1) under the rear lower corner of the air cleaner. Reposition the line away from the air cleaner if necessary.
Install the air cleaner assembly. Refer to the Air Cleaner Assembly Replacement procedure in the Engine Mechanical section of SI.
Install the air cleaner intake duct. Refer to the Air Cleaner Intake Duct Replacement procedure in the Engine Controls section of SI.
Install the fuel injector sight shield. Refer to the Fuel Injector Site Shield Replacement procedure in the Engine Mechanical section of SI.
On 2005 Pontiac Grand Prix vehicles built after January 1, 2005 and all 2005 Buick Allure/LaCrosse vehicles, check to see if the A/C compressor has an
inertia pulley. Figure 1 shows a compressor with a non-inertia pulley. Figure 2 shows a compressor with an inertia pulley. If the A/C compressor has
been replaced during a previous repair then the compressor currently on the vehicle may not have an inertia pulley. If the A/C compressor does not have
an inertia pulley, then install an A/C Clutch Assembly, P/N 89018605.
Engineering is currently investigating a permanent solution. Once the solution is available, this bulletin will be revised.
Parts Information
If the A/C compressor is replaced for another specific reason and the replacement compressor does not have an inertia pulley, then be sure to transfer the
inertia pulley to the new compressor before installing it on the vehicle.
