: What is this part and where can I get it??

07-19-11, 09:16 PM
I was looking up under my 2006 CTS-V and the plastic piece that looks like it protects the underside of the engine is held on by a number of bolts - maybe 6 or so of them?

I need THOSE bolts, because it appears almost all mine are gone (may just a couple are left), becuase my plastic piece is hanging down part of the way.

It is NOT the rubber spoiler piece, it's the plastic piece further back than that...

Help... I would like to get these ordered so my trim piece doesn't fall off.

Mike in Yukon, OK... with my 2006 CTS-V (25K miles).

If it is the plastic piece that I think you are describing it is held on by plastic two-piece push pins. They are available at many autoparts stores, but you will want to take one with you as there several sizes. (I have a draw full of the wrong size, some which were sold to me by dealers who looked up the wrong part number.)

If you can't fix right away, I would get under the car and pull the rest of the pins and store that plastic piece.

Would you happen to know the size/part number so I don't have to go through the trial and error myself??

I do not know, I have yet to get the right part. I was just buying some online and from Luke at Lindsay Cadillac to have some extras around. I have not made it down to the auto parts store yet, but others have posted that they found them at Autozone in several sizes.

I just ordered some of these. If they don't fit I'll add them to my collection unusable push pins.

These are the fender well liner fasteners. The Cadi uses 2 sizes of fasteners all over. Call these guys and they will answer your questions.

I ordered and took delivery of some of these and they do indeed fit the front apron that sits underneath the radiator and part of the engine center.

Use zip ties as a last resort

Hi all!! I got my V just last week; I saw this thread and wanted to offer my .03 cents. I was in Home Depot the other day looking for some bolts. Guess what I found while I was there? They have an entire bolt/screw/nut section devoted to auto-related items. Including a variety of the push pin thingies. If this is what the OP needs, perhaps going to the local home depot (nooooo, I don't work there!) and rummaging through that section might get him what he needs quicker than ordering online and hoping he's got the right part. Hope this helps.

All i know is i needed some of these 78449
Got some at the parts house. Identical part but the plastic is to thick and stiff to work.
Close on the copy but fail.
I will try this place to see if there stuff is correct next time.
