I broke my 2006 Jeep Commander with a Hemi 5.7l V8 in 6 days 

That engine is crammed into that bay I have a commander with the 3.7 v6 and it has given me a great 221 thousand miles whit no major issues

I’ve built two commanders and loved them both. My 4.7L with QT2 was my favorite I still miss that Jeep. My 5.7L with QD2 was a beast for sure. Subbed to see what you do next. Good luck on finding a GC diesel

Sorry to hear this! I just watched & commented on your earlier video when you bought it. The '06 & '07's are the years to avoid unfortunately. I suspect that motor overheated before you got it and at that point became a ticking timebomb. Its unfortunately not uncommon on the Hemi on those years. By '08 they'd fixed the valve guide issue, then updated the Hemi for '09/'10. I think the final generation of the 4.7L in the 08/09 is the better engine (also has 16 spark plugs, one for the compression stroke, one for the exhaust stroke for emissions). Solidly built and no MDS systems...just all 8 cylinders firing all the time as God intended. Regardless, its worth fixing.

So glad that your family is okay. I would have done the same thing. Family first!

in looking for a vehicle I ran into those the other day .... Car Wizard says ...stay away ... now I see you with yours . They look lovely but I'm scared ....TKS !

Om642 is a great unit. Difficult job though, and super expensive on spares. Hope you get it done with something rather than scrap. I just salvaged a 5.7 commander from a friend here in the uk “super rare” but I have the 3.0 v6 already with some mild upgrades. Surprisingly they are about the same for speed, except I’m getting 29mpg in the diesel, and 11 in the hemi 😂. I do love the concept of Hemi though. Good luck with your build, glad you got yourselves safe before saving the motor. Family first.

Was so excited to pick one up today and the alternator fried 20 minutes into the test drive, was such a great Jeep but really soured my experience and confidence in its reliability.

Same thing happened to me.. I have a 2006 commander with the 5.7... had 106000 miles on it.. put maybe 20 miles a day on it, drive town miles mostly, not highway miles, no hard off roading, maintenance done regularly, oil changes etc.. went to a store, shut it off, went to turn it back on and NOTHING!!! No warning, no ruff idle, no smoking... when I say nothing warned me, I mean nothing. Took to garage, pistons came up and smacked the hell out of the plugs .. needless to say, new crate motor was dropped in. The truck is in great shape, no rust, no damage.. when I say I take care of it, I really do... and for a 2006 with no rust in PA, that’s good..ie salt brine lol . So it was either go buy another vehicle for same price or more and not know what I’m getting as far as issues or fix it. I love my commander. She’s a beast for sure. Plus got a 3 inch lift/leveling kit on her. She’s a looker. But hell on gas lol... glad I work close to home lol

I had your epiphany working on my ram. Couldn't belive a near 300$ estimate for plugs. 120 was just the plugs. Doing it myself wasn't bad until the back passenger, had to take parts off the truck even using swivels.

Bummer about the engine, glad you and the kids are OK. But I gotta say Diesel! Diesel! Diesel!

I just bought one with a melted number 7 cylinder. I’m rebuilding it but I would love to swap it into my fox body. Would be something different. Hope you get you’re Jeep going again.

That would be awesome best of luck bud

That sucks. Good luck going forward on it. Actually you're having my luck with v8s too. Except my ZJ.

There are so many commanders for sale on sites with blown engines : head-gaskets etc

Love the optimism man. Rolling coal in that commander would be pretty neat.

"SIXTEEN SPARKPLUGS" Yah, it made me giggle just a little bit. I had the same response on my 05 2500 first time I changed plugs. Doing a plug wire change is even more "enlightening". It sounds like you actually may have hydrolocked the plug out of the head, hence the oil in the plug cavity, or, there may be a gasket leak there also. Is it seized??

Are you replacing the engine with a diesel? If so, will you post videos on diesel transformation?

So what do u suggest to a new buyer of a used commander to do first to not blow the engine

Subbed because I have the exact same one....question... You said its the same body as the Cherokee...so will the skid plate/straps fit from the Cherokee...thats the problem I'm having now😕

I suspect it had a bad head gasket when you bought it. Diesel swap it with an inline, at least that way you can work on it.

I have an '03 Rubicon that I daily drive and was thinking of something more comfortable to drive daily when I saw that you purchased this Commander. That got me to thinking and I have been looking locally for one. I have a question for you though. How many miles was on your Commander when you purchased it? Most of the thing I read state not to get the V6, but that the Hemi has cooling issues. I was just wondering before I pull the trigger on buying one. Thanks, and I love your content.

I keep hearing all the XH commanders where diesels. Mine is also an XH but is the 5.7 not swapped.

The average cost for a reman hemi is around $3K. When you remove the motor it will be much easier to do an autopsy on how it died.

Make sure you only use the orange coolant.

how about your Jeep commander now? I am consider buying a 3.7 v6 2006 Jeep Commander 2006 with 140k miles. I like it outlook and drive test but still need to see more videos about it. If you have any opinions let me know. Thank you :)

Hi... new to the channel. Just curious how many miles? I thought V8 Hemi were tough, if maintained.

Valve seat dropped. I had mine bored .020 over on my 05 dodge magnum. Valve seat falls out on this hemis 03 to 08 cuz of overheating.

Where Off I-85 are you? Used to live in Kenbridge...

So, what do you think happened to the engine? My engine oil cap also has "milk shake". However, the engine still works...

my 07 commander runs smooth then cuts off out of the blue..could be during idle could be at 60 mph ....any ideas?

Check out craigslist in Prescott, Arizona with keywords "jeep commander diesel". Man partially completed om642 swap into '06 Commander. I haven't jumped on it because I'm uncertain of my electronics skills to make it work. Maybe you can?

If I want to convert my 2008 jeep Commander to Diesel how much would it cost?

Do you have an update on your jeep commander?

Wt about 5.7. V8 hemi commander engine?

What did you end up doing with the commander?

How would the cylinders hit the spark plugs? Unless of course, they were the wrong plugs (they looked really long), but it wouldn't have run 12 feet.

Diesel swap would be cool 👍

just found one same as yours, like twins.... TBH i am not sure to buy it or not. I am hearing bad things about those trucks. Another question is, do they have the infamous CVT transmissions? they are such a POS, but still... I like the way they look. Anything new on your Commander yet?

How many miles are on the commander?

The 2007-2008 Jeep Grand Cherokee diesel used the Mercedes OM642. Check the link below for a list of potential donor vehicles. en.wikipedia.org/wiki/Mercedes-Benz_OM642_engine

Another great example of, “buyer beware”. If you had researched this engine you would not have bought it. The 4.7 V8 is the reliable engine.

16 spark plugs ...never would have guessed that one.

Uff dah...

Dude...how frigging tall are you? You're like a head taller than then car?! Lol

If you're from Texas I am selling my commander 2007 V8 5.7 4x4 quada drive 180.000 miles and running strong

How much m8les on that bad boy
