great video, GM says to also replace the boots when you do a plug change, and since it's that far apart, take out/clean the Map Sensor, with Map Sensor spray cleaner, then take off the throttle body and clean it and clean all the parts replace the air filter too, get a new throttle body gasket when you reinstall the throttle body, clean all the electronic plugs with the proper cleaner before plugging them back in too.
Hey Leafy! Great, Great, Video! Costs $400 and some dollars to have someone else do it. Thought it was very detailed and consistent. Your video will save people a lot of time..and money.. For new ones, it looks complicated, but you made it easy.. Thanks AGAIN!
Sir, Very well done! Loved the pace and detailed step by step process. As an inexperienced auto DIY guy I now have confidence I can get this done without breaking stuff lol.
When changing the plugs, remember to check the wiring: Some wiring is made so that the individual wirings for coils can rub against the cylinder head. That may cause misfiring or blowing the fuse 33. In the latter case everything works except starter and the engine, and it triggers no codes, so no scanner can detect it easily.
Going from doing plug changes on my 2005 Expedition 5.4L where 4 & 8 are absolute nightmares to get to under the firewall, I'm actually looking forward to a tune up on my 2007 H3. 😂
Actually the engine, transmission etc and most of the frame are similar to Colorado, but front suspension and all the other stuff are different or just slightly similar looking. Electrics are mostly same. I have a H3, and as I always want to have some kind of repair manual, I bought the one for Colorado. However, it was a disappointment because of all those things that are different, so the manual is not as useful as I hoped. The video is excellent because it highlights the need for cleanliness. Also doing steps in a logical order concerning tools. The use of compressed air helps getting rid of loose dirt, but then care must be taken not to do damage with it or blow dirt into exposed things when the intake clean air tubing and PCV-hose are disconnected. The best part of the video was finding the fault that triggered the need to replace plugs.
Just wanted to say Thank You for the pleasant video, unfortunately my Dad liked Fords when I was little and they were always breaking down and he was forever busting a knuckle on something and I got to be the one "helping" him and getting yelled at violently when shit wouldnt work. LOL. O Well. :)
I have a question. I am doing the same job on a 2006 hummer h3. All of the ignition coils feel like they are stuck on something. They dont just come out easily. I was wondering what is the best way to deal with that issue?
hello i have a 06 h3 hummer and i am having stalling problems. the truck every so often stops while im driving the steering wheels gets tight and the truck just dies while the radio and the lights are still on. my question is have you ever had this problem or know anything about it. i tried buying the new rockies bypass for the passlock security system. That didnt work. I really feel like the passlock system is shutting down the fuel to the engine. Your thoughts.
If the starter works after stalling but the engine won't start, the passlock light may be blinking and is on. If the starter will not work, the PCM may be failing or the BCM may also be failing. Then the passlock light is not blinking as the system thinks that everything is just fine. It does not even trigger any codes. My H3 did just that. That is one heck of a fault to diagnose...
This is a super video. I am going to use it to do mine this weekend. Much appreciated! I have a question....you called the plugs the good ol' ac delco 125992. But mine have a different #.....and I googled 125992 and got something far from spark plugs. Is that the wrong # you mentioned or do I have the wrong plugs? Again, excellent video for an amateur like me, thank you.
Hi, excellent video, thanks for posting it. One question: how do you move the wire harness over coil #1? Did you just pry it up off the engine block? I would like to move it without breaking those plastic clips if possible. Thanks.
Where can i find or who makes the valve cover for the 2006 hummer h3, i have search all over and i cant even find an after market one.. i need the Valve cover and Gasket, need help anybody..
Hello again....This video was so helpful, and I thought of it when I had the following question-I cannot figure out how to swap out my rear brake pads. I am definitely not a pro, but if you or anyone who reads this knows how to do it(take apart caliper?), please, please respond with any advice, thank you!!!
@@leafygreentree So the 2008-09 h3t would be the 2008-2019 Colorado chassis? Im trying to figure out if i remove the bed would a AUSIE ute canapy fit. They say on the 2013-19 colorado.
Hi man ,the Hummer engine is so high to reach ,how did you raise yourself toThe level of the engine so you can reach all the areas ? Did you use a small ladder ora chair ? Thanks ..
Thank you ,but the last Coil it’s hard to take out because the electrical wires blocks the coil , could you please tell me how did you manage to remove that electrical wires or losened it so you could lift it up and then take out the coil ? Thanks ...
hey mate, i just have the same color hummer as yours and i'm looking for the color code as i need to paint a panel. Is there any chance to give me the code if you can please. Cheers
HELP.... Hey, love the video, BUT III changed out all spark plugs and now engine light is on and says engine is running lean. No holes in tubes, air tight seals, air filter is new with good deal, and everything is tight. Any thoughts? The light was not on before the tune up.
celui-ci, est très bien expliqué.... et simple a voir.. sauf, la caméra...= mal placer par moment, pour voir le détaille... principal.....! MERCI... QUAND MÊME.... pour la démonstration. visuelle.
Just a heads up I think you should change the shirt you have on. You've had it on quite a few videos. If you need me to send you some new ones. Let me know thanks. Jennifer. I'll be more than happy to send you some shirts for you.

Awesome video! I was able to change all spark plugs easily using this video. Saved me $215! Thanks for a great diy video!
Sir,
Very well done! Loved the pace and detailed step by step process. As an inexperienced auto DIY guy I now have confidence I can get this done without breaking stuff lol.
Thank you for this video! It was amazing and I was able to change my spark plugs on my own! :D

InstaBlaster...
I felt like I was in an actual class setting how much I’ve learned, thank you!
Disregard my question.....I was able to zoom in on your new plugs, and realized that they are indeed the same ones I have in my hand.....thanks!!
Thank you I did my first spark plug change on my hummer h3 and your video help me a lot 🙌🙌🙌
Perfect and simple, your work and your explanation

Hi sir

Great video man! I especially appreciated the obscure "Count" reference... lol
Thank you bro,thank you for your video i am going to change my spark plugs

omg i can not believe how easy this was, i did this on my Hummer and it was so easy lol
One of the best one's ive seen. Well done. Thanks
Absolutely great video man, helped me out a bunch, thank you.
Thanks for the great video. One question is,
why was there no need to gap the spark plugs?

i have an extra!
You didnt use anti seize on the spark plug threads?
Thank you it is very helpful and clear thank you again

Great video awesome detail, one question I do have is what are the plugs gapped at???

He broke it not properly relieving the snaps
hi which hummer engine is more reliable, old 3.5 or newer 3.7. Thank you.
do you know the cylinder order from front to back
Cylinders are 1 to 5 starting from the firewall? In 1 2 3 4 5 order?
@@leafygreentree wish it was that easy. Cant find it anywhere for the it 3.5 l
Where can i find or who makes the valve cover for the 2006 hummer h3, i have search all over and i cant even find an after market one.. i need the Valve cover and Gasket, need help anybody..
@@leafygreentree Thank you
Will this video work with a 09 H3?

I am definitely not a pro, but if you or anyone who reads this knows how to do it(take apart caliper?), please, please respond with any advice, thank you!!!
Follow someone more reputable, brakes are too important to be asking someone who makes many errors . I mean that in all honesty
Have you ever had any problems with your a/c?
Nice Job !!!
Are the hummer h3t and colorado the same engine?Chassis?Truck bed dimensions?
@@leafygreentree So the 2008-09 h3t would be the 2008-2019 Colorado chassis? Im trying to figure out if i remove the bed would a AUSIE ute canapy fit. They say on the 2013-19 colorado.

There is a sticker in the glovebox with all the codes.
Thank you very much leafygreentree!
Great video thank you funny count olf laughs
Well done!
why was there no need to gap the spark plugs?
Yes... I did check and that is about what they were. ... thanks
Thank you!!!!
HELP.... Hey, love the video, BUT III changed out all spark plugs and now engine light is on and says engine is running lean. No holes in tubes, air tight seals, air filter is new with good deal, and everything is tight. Any thoughts? The light was not on before the tune up.
Did you ever fix this? Sometimes, it’s a code that just needs to run out.
Don’t forget to gap them nice video
Thank u very much 😁
Wow i never knew that a hummer had the same inline 5 my colorado has haha so basically i own a cheap hummer thats nice to know 😂
They also have the same chassis.
Спасибо дружище!
just so you know, the spark plug torque setting is 13ft-lb ;)
Awesome video! Thank you so much! Thumbs up from me... Stay safe... Rico
Too redundant on your descriptions. And you kept getting your arm in the way of the camera.
Kinda hard to see thru your arm

Hasta con manga larga se puede hacer...
Thanks Mr! I wish you were my Daddy 😉
first thing you gonna do is to disconnect the battery
Your arm and sleeve blocked alot of the video
Wait until you change the front wheel bearings and hub assembly. Not fun.
I’ve done it on mine. No fun either

Torque the spark plug
