Grill replacement on T1 Sierra

[Kintnerboyredoubt]

I did a search and found one topic on the subject but was still not very clear... has anyone replaced their grill? I bought a blacked out one off of eBay and tried tearing into it today but couldn’t figure out how to remove the lower valence to gain access to the lower bolts on the grill. I could see 2 clips near the headlights but kept feeling like I was going to break it so I gave up and put it back together. Any tips would be appreciated.

Perfect, that’s exactly what I needed to hear. Got as far as removing the upper tray top 4 bolts and felt liner on the passenger side before giving up. I’ll call around to some body shops on Monday and let them deal with it.

Don't have to remove bumper.  Have to remove valence.  Easiest place to find instructions is from any vendor of aftermarket bumpers.  It's not that bad.  Definitely not worth paying someone $130 if you're mechanically inclined.

This bumper is god awful (from my perspective anyway...) anyhow the it includes clear and concise instructions for grill and valance removal for anyone interested

Update, grill is installed, wasn’t too bad only managed to break one clip near the headlight. Cheap grill off of eBay was a bad idea, it was mis manufactured and missing the mounting tabs for the top 2 10mm bolts as well as half of the sleeve to install the weather striping. I went ahead and installed it but will order the genuine gmc one and install it for replacement.

I'm going to agree and say that bumper is HIDEOUS.  Great job digging in and replacing the grill yourself though!

Based my my research, the first 3 minutes of this video would work for the GMC grill removal as well.  I am trying to see if there are any sensors that need reprogramming (for certain models like the denail's) by the dealer.   I want to add an LED Light bar and planned to try this method in the video below.

Sorry to rain on your parade but the gmc grill has 3 10mm bolts on the bottom of the grill that have to be removed. The only way to access them is to remove the entire front valance. Would be a piece of cake if it were the same as the Chevy for grill removal. Good luck.

Thanks for the confirmation.

Bringing back a slightly older post...

 

If you pull the front bumper (I have a base model without fogs, so I don't think I have any wires to worry about), can you sneak out the bottom bolts that hold in the grill?  Or is the lower valence under the grill still in the way from removing the bolts (and/or pulling the grill up)?  

 

Thanks for any help!
