Hi all,


This is my first time posting on this forum so I hope I'm in the right area.  My "service air bag" light came on today and I knew right away what the issue was due to the popular corrosion complaints.  I decided to check for myself and sure enough, one of them is cracked.  What I'm having difficulties understanding is why the retaining bolt is going from the top down.  You would basically have to remove the radiator to get this thing out.  I really don't understand why mine looks nothing like there other videos and images I've seen online.  For everyone else, it seems as easy as getting underneath the truck and just unplugging and unbolting it.


Has anybody else had a similar experience as me?  Is there an easier way to remove this without having to take out or remove the radiator?  I noticed that the end of the bolt is star shaped.  Is this so that you can fit some kind of tool over it to unscrew from the bottom end?


This image is from the underside.  I removed the plastic skid plate to get a better view.  I should also mention that this is on a 2012 Chevy Silverado 1500 LT.  With a 5.3 V8, not that it has any relevance for this.
