Fantastic video! This is to the point with necessary detail. Thank you!!
how do you know that this is a problem?
Doesn’t motor oil corrode an swell o rings
Did you have to pull fuses before removing rail…fuel pump and injector fuses?…start the car until it dies , to relieve the pressure?…anything else?…thanks…
Hello my friend… I have a HUMMER h3 2007 3.7L and I have a problem with the engine cutting, weakness and vibration of the engine and I want to change the injectors according to an examination and it was found by Injector No. 1 that is not working properly I want the correct number of the injectors because a year ago I changed them and the problem went away but unfortunately it came back and the reason Injectors, so I want original ones. What is the code for the HUMMER h3 2007 3.7L, thank you
Lol. You dont include all the stuff.you gotta remove to get to it. Including the battery and like ten different connectors. What about the fan shroud also? Your vid is sarcastic. Lol. Wish it only took in hour. This is an all day 1400 dollar job at dealer.
What made you know it was leaking ? I have a misfire on cylinder one confirm compression is good and spark switched coils and plugs this is the next thing I’m thinking
I just did this on my 2008 H3 and I have absolutely no idea what sorcery you used to be able to get to all the intake bolts without having to go through the wheel well! I actually tried to start by going in from the top like you did but quickly abandoned that idea! I was at it for probably 4 times longer than you were as well, lol.
whats the best stuff to use to put in fuel tank to clean clogged injectors?….i think thats what my problem is….if not, next step is to replace injectors….thanks !!
I'm glad your on here making Hummer H3 videos. Im DIY guy and do everything myself but i always watch videos to have tricks or tips. Finding stuff for Hummers is hard, its nice knowing your videos are up to date and very well explained. Thank you for taking time out of your day to make videos like this.
Great video! I have a bad injector. Did you reuse old intake manifold gasket or get new one! Throttle body gasket reuse or new?
You are the best !!
Would have been nice if you showed how to remove the belt. That requires a special tool and instruction on how to use it would be helpful.
1. Hello and Thank You .
2. Do you know what the little valve looking thing is that's on the Aluminum tubing leading INTO the Fuel Injector Rail. About 3" from the rail end on tubing. At 3:15 you can see it sticking down, looks like your black cap is gone ??…. NOT the A/C one. Can I use this to blow cleaner into injectors on rail to clean them, with out ANY Dismantling ???? Of course I would pull the fuel pump fuse…
3. " upgrade to better ones" injectors that is, what did you end up going with ??
Thanks again for all your Time and knowledge 🙂
“If it ain’t broke don’t fix it”!
Awesome video! Very well shot edited, and hearing the snaps and clicks was very satisfying! Great job!
Do you need new intake gaskets and throttle body gaskets when you replace these Injectors
Skipped over quite a few details getting to the fuel rail… removal and installation of intake bolts are much easier accessing through the driver's side inner fender
mileage Per gallon
Awesome video. Thanks
Notice any difference after changing the fuel injectors? If so what is the difference? Does it idle better? How hard was it to take off the intake manifold? It looks like a pain in the ass. Any problems after removing and installing it? I want to do the same thing but I'm worried about messing up the intake manifold
