2017 Silverado - Fuel Injector Replacement Help

Looking for help/instructions on replacing fuel injector/s for a 2017 5.3L Silverado. Truck has 80K miles on it and a #5  misfire. Dealer ran a diagnostics and said the injector needs to be replaced.

 

I found a couple pictures on the forum of the fuel injectors but very little information on steps to replace them. The only videos I could find online were for older models with a different injector diagram. Talking to the dealer they quoted me $770 to replace a single injector, gaskets and piping associated with the job. 4 hours or labor and $240 in parts. 

 

Are there any good instructions or videos out there on replacing fuel injectors on a 2017 Silverado?

I've never done a job like this but consider myself mechanically include, is this an easy enough job or should I leave this to the dealer to do?

I know they say if your replacing a single injector you might as well replace all 4 on one bank but is that really necessary, $110 a piece and if the other 3 are fine why replace them?

 

The dealer said the piping and gaskets must be replaced even for a single injector replacement job. Is this all necessary? I've never had another vehicle with injector problems so this will be a first. 

Parts quoted-

12687650           (1) injector

12626354           (8) gaskets

12677002           (1)  pipe

12677004           (1) pipe

 

Any help, links to instruction/diagrams or videos would be awesome! I enjoy working on these projects rather than paying someone else to do the work since you learn something every time. I also want it done right.

 

Thanks all in advance!

If you pull one bank of injectors and replace one, the other 3 need the lower seals replaced. Requires special tools to install and size the new seals.

I'm looking online now at parts, I just found all the parts I listed above to half the price the dealer quoted me.

 

Would the replacements for the lower seals be included in the "seal kit" part # 12672366 ?

 

Are the special tools something only the dealer would have? 

 

Why replace (8) intake manifold gaskets as the dealer has parts on the quote?  12626354           (8) gaskets 

 

It seems to me someone out there would have put together some step by step or video of replacing these since I've read several forums with guys having bad injectors on these new trucks.

I can't seem to locate the injector r&r in my alldata mobile app. I'll check on the pc once I'm home.

Man, on a 2017 you need new injector already?

You should contact GM and complain.

 

My 2011 BMW x5 needs #6. Dealer quoted $1400.

Getting it done elsewhere for $700. Hope its not that expensive for you.

I've received two different quotes now from dealers for $770 to replace a single injector. Even though only the #5 injector is misfiring and bad they are recommending replacing all 4 on the side. To replace 4 it would be around $1200

 

I can buy all the new parts for around $150.  I was hoping to attempt the work myself and figured even if it took me a day to do the work at least I learned something and can do it again next time. Reading more and more forums it sounds like this can be a common problem and I don't plan on paying $770 each time I need an injector replaced.

I'm not finding any info on injector/ orings when i search through alldata on the pc. I spoke with a rep last week and he said they have the ability to add info. I'll see if they can add that r&r along with the emissions.

If you look up super charger instruction manuals, they give you step by step instructions with color photos for removing the intake.

I ran into the issue of not knowing and took mine to the stealership and paid $1000 for one injector and a ignition coil.  Never again.  I had searched for days to figure out the issue and finally came upon this video where he did this on a suburban or a tahoe but it is the same process for a silverado.  Looks time consuming but the parts are less expensive.  Roughly under $400 if you do all the parts.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
