Front Impact Sensor

[itsbo1313]

So I've had an airbag light and service airbag warning in my DIC for a while. I've doing research and ordered the part. Everything I've read and watched says it's easy DIY. Located under the radiator, remove the skid plate with 15mm, remove sensor with 10mm. I get under the truck remove the skid plate the sensor is under the radiator but I have to remove the fans first. Is this specific to the Denali?

I didn't remove the fan when I replaced one on my wife's Denali.

If this is in the wrong section please move.

as soon as you take the splash guard off they are right there one on each side under the front edge of the metal bumper, you can reach up and feel them even with the splash guard on. the left and right are the same so if one side does not make the code go away you can swap it to the other side.

What year is your Denali?

I was able to touch them but the screw/bolt head is above so I can’t get to it.

2008, It only took me 10 mins. Make sure you disconnect the battery

just take the splash guard off, they are bolted to the bottom front edge of the bumper there is no bolt above them.

I took the splash guard off. My sensor is not held on by a 10mm bolt. All the videos show a 10mm bolt from the bottom up. Mine is attached from the top down. I can’t tell what size or type of fastener is holding it on. The head of the bolt or screw is above.

can you stick your phone in there and snap a picture it shouldn't be on top, what year is your truck?

It’s a 2012. Both sensor are mounted this way. I put the splash shield back on. I’ll get a picture tomorrow morning.

Different part for 2010-2014. Everything I’ve read and watched is for Pre 2010

mine is a 2012 there on the bottom, they have been since at least 00 as far as I know, even the GM service manual shows it on the bottom

I assume you have the replacement on hand to install?, the existing one will have the exact same bolt

 

[itsbo1313]

Yes, I have the one in your picture. Dorman 590-225. Dorman 590-224 is the one everyone on youtube is replacing for pre 2010. What your picture doesn't show is the fan right on top of the radiator support or whatever that frame piece is. No room between for even my hand to touch the screw head. But I'll jack it up again and try to get a decent picture. It's funny that there isn't any videos on youtube for a 2010+ Silverado, Sierra, Tahoe, suburban or yukon airbag sensor.

that picture is from the 2010-2014 factory service manual as is the procedure to r&r it in the next photo, if you had to take the fan out it would say "remove fan" etc, etc
looks like it has a torx bit instead of a 10mm, you will need to loosen it and slide it out of the notch

Thank you for all the replies. I will get back under it in a few.

I couldn't tell from under the truck and I have never seen a hex head with male torx tip screw. I just saw the hex head on the other side when I examined the new part. So now I just need to buy a torx socket set. Thanks again bro. You're awesome.

a small socket should fit on the bottom male hex

Broke the tip off. I guess I have to pay someone. It's an E5 torx if anybody tries in the future. I don't know how I could have not broken it. With a 1/4 in drive ratchet I couldn't put much torque on it. And it looks like someone else tried and broke the plastic clip. Bummed.
