Auto body repair & detailing: grill removal, buick rendezvous, splash shields

Question
I have an '04 Buick Rendezvous, and I'm trying to remove the front grill so I can install a transmission cooler. I can get it most of the way off, but there is a couple of areas that I can't seem to find how it is attached. I would normally get a chiltons, or haynes manual, but they have not published one for this vehicle.  Do you have any diagrams, or can you explain to me the correct procedure?

Thank you

Ther is not a manual available, only a GM garage can print you off detailed instructions on grille removal. let me save you some trouble- it's easier to remove the front bumper to access the area you want in. You need to loosen up the front of the splash shields in the fenders to access the 4 bolts holding the corners of the bumper cover to the fenders. remove all the attaching clips along the bottom of the cover, and all the ones across the top in the hood area. You may need to remove the headlamps, but if memory serves, you need to leave them in, because you need to remove the bumper to remove the headlamps. The bumper and grille come of as one big unit. If the grille extends over the headlamps, and seems to be attached directly to the lamps, use a stiff putty knife to pry loose the clips. Then, the entire facia will come off. It's very tight up front, you will need the cover off so you have room to work. Bill
