You can silence the locust on editing by eq ing the high frequencies out.

Those I-5’s are great engines if you give them the proper care and maintenance. I used to have an 2006 Hummer H3 (3.5L) with 305,000 miles before selling it. Still was on original engine and running like new.

I bought a 2005 GMC Canyon new with the 3.5. At about 8,000 miles a valve spring retainer broke and dropped on the piston. GM send engineers to inspect the cylinder head and block. Ended up replacing the head and piston. Gave me a 5 year 100,000 mile powertrain warranty.

This may be too late for you. Sibling had same issue. Timing chain tensioner is gone. Needs replaced and this is overhead cam. Cam may be damaged. Engine is good.

Great videos! I just bought a 2006 H3 with 153,000 mi. on it. Runs like a new car so far. Hopefully no problems.

I also see that you have the normal temp gauge where it always hovers above the halfway mark in between the three quarter. From what I understand that is normal from Bad calibration of the temp gauge

Also you can look for 2004 trailblazers mine had one in it.

You can put a 5.3 in this. Mounts up just need a 4l60e 5.3l bell housing.

Those dash lights used to be called IDIOT LIGHTS....because idiots would ignore them and keep driving. Kinda like what you did. Too bad you destroyed this little hummer. The 06-07 h3 had defective cylinder heads. They were under recall up to a certain mileage, if yours made it past 60,000 GM considered your head non defective and did not replace it. How do I know this? Been there myself, my engine missed the cutoff by 8000 miles so I paid the full cost out of pocket. Putting transmission oil in the block thinned the oil and made things worse....idiot lights mmm,mmm. Oh well.

Fan Shroud is missing that could be why it was running a little hot when it was running okay.

Someone put wrong oil in too heavy and threw timming off on camshaft sensor you have bad valve or premature detonation is burning spark plugs messing timming, you have metal to metal knock. Heavy oil destroys this engine.. Your pcv valve hose if clogged will cause detonation burning spark plugs throwing timming off.

These videos are great!!!. My sister has a 2008 Hummer H3 Luxury with 140,000 kilometers on it. It's a mission with the check engine light, lol

Take it to a damn mechanic. Good Lord man

Wow! That didn’t take long. I really thought the engine would last a little longer.

What year Hummer? We bought a brand new one in 06 and had the same issue, Hummer said they had bad heads when they first came out, they replaced the head and problem solved. They said said the first run heads weren't cured enough

Luckily it also came with and LS....time for a swap

The 06 and 07 with 3.5 had bad heads. Valves wear the head fast. Cant be fixed only replaced. You need a new head but I'd recommend upgrading to the 3.7 that's in the 08 through 10.

I meant water temp. Not oil temp.

Man! I had same exact issue last month. Same sound and oil light. Died on freeway and had to restart. I didn't want to have to pay the mechanic for a teardown, so I found another 2006 Hummer that was T-boned, and bought the motor for $2,200 and had it installed. So far it's running fine and I never did find out what that knock was, and why the oil light would come on and off, and why it kept stalling on me at red lights and on the freeway when I had to stop.

Okay if you guys are buying a Hummer don’t buy any later than 2007 05 to 6 have the 5.3L engine a lot of problem with them. The 07 have the 3.7 and they are much better ✌🏾

Can you see how the oil temperature was too high?

Change your radiator, this hummer have high temp.

Looks like you didn’t have any antifreeze in the container

Hi there , first thing first is to Run Compression Test , and then Leak Down Test to see if inside the Engine is good ....

why not put the 4.2 in it

That the big problem with orphan vehicles your basicly on you own. They built to many to be collector items.

I bought the exact same h3 color and all for my daughter. It’s an 06 with 90k

Do it your self is the way to do it way to go get her done man

My dream SUV💓 God give me hummer 🙏

Bottle of " seafoam" , in the oil was safer .

selling any parts from it?

Still no new engine for the hummer?

Try seafoam

Dude your out of oil!!!!!!!!!!!!!

I see your temperature is above normal. I had this same issue and GM told me it was normal. One day it got too close for comfort. Before that the Water Pump went out and it was perfect timing. I wind up replacing fan clutch and water pump. Its been at normal temp for three years now. I've had the h3 for five years. Fan clutch and water pump was bad. Oh yeah might I add I also replaced the radiator as well. I had extra money. And was on vacation lol. Radiator looked old so being I was changing water pump etc anyways. I just did the whole thing. I know hummer don't get alot of love but they're really reliable vehicle long distance and every day travel. I have 172 thousand miles and change. I bought it with 67 thousand and change. I've been Texas and back a few times Oklahoma and back a few time etc I live in Tampa FL. Once you get a good working engine you will also love it.

ekspecially. hahahahahahahahahha

So your going to spend money on another crappy "GMC" built engine?? Smart people learn by facts....Hummer engines have always been nightmares.

i rebuilt mine for under 2000

Like the channel .

NEVER BUY GM...

Well it would be nice if you're going to put another motor in it at least tear that one apart and find out what the hell is wrong with it so we know don't just leave us hanging
