Removal & Installation
Although the basic W-Body platform is shared among four GM manufacturers, different grilles and fascia panels give the vehicles their identify. This may change from year to year and depending on the model and may vary between different Regular Production Options (RPOs). Since most all grille panels are retained with a combination of tabs and screws, the following should suffice for most all W-Body vehicles.
Open the hood.
Remove the nuts from the grille locating studs.
Remove the grille from the bumper fascia.
Installation is the reverse of removal.
