Thank you. I’m about to buy a 2005 2500 5.9 Cummins tomorrow and I’ve been typing all this in my notes. Haha thank you.

I enjoyed this. Good info for new owners as well as people like myself. I've had my '03 5.9 that I bought brand new. I'm not a mechanic, but I have done many of the easier tasks related to the common weak points of the truck, including the cracked up dash and the heater/Air doors that strip out. The FCA caused problems for me, and I think it is a common thing on the 5.9. Seeping transmission lines also. I have been told to keep a spare Crank position sensor on board too. I need to order one.

Very helpful, im looking at a few 3rd gen cummins at dealerships around me and trying to find what to look for in issues. Thanks for the Vid!

You really have passion for Cummins knowledge

Great video man, very helpful information included! Been watching your stuff for a while now and you are the most scientific cummins channel I've ever seen, love how you back a lot of your stuff up with data. Keep up the good work bro!

Before you ever test drive the truck, make sure the engine is cold and start it and check for blowby, if possible ask them to not start it before you get there. It will have more blowby when it's cold. When the rings warm up after a test drive the blowby can go away because the rings warm up and seat.

Very informative and to the point.

Get the 3rd gen trans cooler lines from power driven diesel, they’re the best lines hands down.

Love this video. Very realistic assessment of where to find leaks and what to look for when buying a cummins 3rd gen plus a realistic undercarriage helps. Most undercarriages you see online are spotless, not what you see in the real world.

That was great intel ! Thanks

Thanks for video man ..going to look at one and this helped bug time cheers

I’m looking at getting one in the near future for myself as i’d like to be back in a truck and much prefer something that i can rely on

Fantastic video bud!

And I wouldn't worry about oil leaks from the oulpan it's easy to do. It's the front and rear main seals you want to look for.

the 06 to 08 dash and front clip will just bolt onto 03 to 05 style 3gens. my truck had it done before i got it

If you get a 3rd get ... If it has not been upgraded assume you will need to upgrade the linkage, gearbox , ball joints and trac bar, upgrade the fuel filter and replace the injectors at some point.

I'm looking into purchasing a 2007 3500, based on what you said about the emission or EGR are you suggesting maybe to stay away from this particular years model truck?

Thanks alot for all the info you helped me alot im about to buy a 2005 with 210,000 miles but has a new motor with 60k miles on rust free little sweat on the diff

[just, bought a 2004, Dodge ram 3500 diesel truck with low mileage at 164 400 everything checks out great]👍🙏

Grabbing the tire up and down can also reveal wheel bearing play

Had many Dodge Cummins 1st, 2nd and third and all had serious blend door problems and very expensive to repair around $1,000 to $1,500

dang. super helpful. thanks.

Great video, subbed.

How does a blow by test work if the cover is already vented to atmosphere?

I just ran the overhead on my ‘08, I don’t think it’s ever been done judging by how hard it was to pry off the valve cover. Ended up with a split valve cover gasket, so that was fun. Unbelievable how quiet the engine is now. I guess after 210k miles, it was due.

Excellent video! So funny you mentioned the rpm cluster on the 06 because mine started misreading after 150k miles. I just left it though, because when I do long distance trips it finds itself. As long as my speed one works I’m happy although when I put on larger tires with the stock gearing it wouldn’t read sometimes it would give up and just stay at 0mph even though I was flying on the highway lol. Ever since I upgraded the clutch and gears though it drives better than it has in years. I’m looking at 2018 g56 Cummins 2500 4x4s now, but definitely would want it deleted after purchasing. Otherwise I Gota look at 2011s.

Awesome video ❤❤❤

Great video, very informative!

How do you know things are first second or third generation you go by the trucks here?

I have a 2007 5.9 with a g56, hopefully never have to buy another truck.

I ended up trading my 09 in. I loved the truck but too many problems and a money pit. Unless you can delete it yourself though and where i live i cant the regen sucks ass and the DPF was a pain in the ass!

Looking at an early 2004 with 170k miles… thanks for the info

So what if a kid that’s a diesel mechanic get a 6.7 ? what should he whatch out for ?

Could a throttle position sensor on its way out cause choppy idle

as an '06 owner.. "yup, got that" "yup, replaced that twice" "yup, haven't addressed that yet" I've replaced 4 injector solenoids (left the injector installed and just pulled and replaced the solenoid). Front and rear main oil seals need to be replaced. Just learned today that my trans fluid/engine coolant heat exchanger has failed because I have the milky white goodness. One more thing, take normal auto parts expenses and x3 because Diesel. Liked and subscribed.

Is that for automatics only? This is a 6 speed manuel

My 05 doesn’t have the sensor on the motor the door says it’s a 04.5

Liked and subscribed, what would year would you purchase?

What could I expect from a 06 with 264k asking 24k?

Gr8 Video. Sounds like my 03 2wd is a SO 250hp with the 47re... unfortunately but hey its at 180k on stock power My tps may be bad since it randomly surges and goes in a high rpm before shifting into the next gear but when I park it and put it back in drive its normal.

What About Dodge Ram 2500 1997 OR 1999 With Hemi Gasoline Engine.

No CATs until 06.5. My 06 had a muffler from factory. Also, ive still got the original injectors at 235k miles. I just use Lucas injector lube/clean every 2 weeks

my 04 had nothing but a muffler on the truck the sticker says it was built 10/2003

Does anyone know the size of hex head socket used to take the FILL plug out of a 2003 Ram NV5600 6 speed transmission? Thanks.

👍

If we gonna look for imperfections is better to go straight to the dealer for a brand new truck

Found one bad trans bad transfer case for 2500 going get it in a couple days

My friend right where your trans lines are your bell houseing is cracked I seen it in your video. Driver side of the trans.

What wheels?

What radiator would you recommend? Nothing insane but a brand that will really keep it running colder

I’ve read before that the 2003 HO model only came with the NV5600 six speed. Later years had the auto as well, but ‘03 HO was NV5600 only.

What’s the best Cummins motor would you recommend? Thanks

I just bought an 2004.5 Cummins after a month I got a check engine light with a code of p2609 I replaced both of the relays. I guess I’m missing something because I can’t seem to get the code to go away. Any thoughts on what to check at start up the heater grid cycles like it should I’m at a loss

Are those trucks for sale

I’m getting an 2005 2500 diesel from my father in law and was curious where do I add the DEF I know the newer ones it’s under the fuel cap but not on this one

so iv read a lot about the power per year and whatnot, my trucks an early 04 with the 6 speed but the valve cover cover says it comes stock with 325hp so im a tad bit confused

Blow by into your valve cover is a matter of the valve seals not piston rings

Damn, this is making me think they're all basket cases.

I’m confused how do I know if I have the 47 or 48 ? I got a 05 2500 ?

looking at a 03 how do i tell if its a HO or SO?

Are u in the bay st Louis/ Waveland area that area looks familiar

It’s a used truck vibration what a joke lol

i almost cried when i saw that ripped center console, it looks like a dog got to it 🤢😭
